6.Nb3

All four plausible knight moves - the other three are are Nb5, Nc2 and Nf3 - have been played, and seem much of a muchness, according to Stockfish19 and Dragon1. 6.Be3? has also been tried, but presumably because the player missed the strength of 6...Qxb2.

10.Nb5!?

The stem game in Mega26, Viktor Korchnoi (2595) - John van der Wiel (2540), Amsterdam 1988, went 10.Bf4 0-0 11.Re1 b6 12.Bf1!? Bb7 13.Qxd6 Bxd6 14.Bg3!?, with an equal game, according to the engines (½–½, 44 moves). Not for 22 years did the same position arise again, at least in Mega26, and then Quan Liem Le (2647) - Ian Nepomniachtchi (2658), Aeroflot (Moscow) 2010, varied with 10...Bxc3 11.bxc3 Qxd3 12.Bxe5 Qxc4 13.Re1, when White had more than enough for a pawn, according to the engines (1-0, 60 moves).

10...Qxd3 11.Nc7+ Kd8 12.Nxa8 b6!?

This apparent-novelty is the top choice of the engines. Artem Kopyl (2327) - Alexander Mikhnenko (2006), Sochi (Russia) Rapid 2023, saw 12...Nxe4?, but this was well-met by 13.Qh5! (1-0, 27 moves).

13.Be3?

The engines prefer 13.f3, continuing 13...Qxd1 14.Rxd1, and either 14...Nxc4 or 14...Bb7. But their evaluations differ, fluctuating between equality and the upper hand for Black.

13...Bb7

Even stronger, according to the engines, is 13...Qxe4.

14.Nxb6??

White has to play 14.Qxd3 Nxd3, and then either 15.Nxb6 or 15.a3.

Missing the devastating 14...Qxe4!

*****

*****

*****

*****

*****

Going strictly by material, using Larry Kaufman's computer-generated values in The Evaluation Of Material Imbalances (minor piece = 3.25 pawns; bishop-pair = 0.5), a rook and two pawns (5 + 1 + 1 = 7) is the same as bishop and knight (3.25 + 3.25 = 6.5) with the bishop-pair (0.5). At first glance, it might even be thought White's connected passed pawns would give White an edge, but the engines slightly prefer Black, perhaps because of the weakness of the white c and e pawns.

16.a3 Bd6 17.c5?!

The engines strongly dislike this, suggesting 17.f3 or 17.Nc5.

17...Bb8 18.f3 Rc8

Here the engines prefer 18...Qe3+, meeting 19.Kh1 with 19...Nc6!?, and 19.Rf2!? with 19...Nd3.

19.Nd4?

White should probably play 19.Re1!?, but the engines reckon Black has at least the upper hand.

19...d5?

Black is winning comfortably after 19...Qe3+ 20.Kh1 Qh6!?, according to the engines.

20.cxd6+ Bxd6 21.Rc1?

21.Qxd3 (Stockfish19) or 21.b4 (Dragon1) keeps White's disadvantage within manageable bounds.

Black to play and win

21...Nfd7??

This turns a winning position into a losing one. The way to attack the loose bishop is with 21...Qa6, when White's advantage is worth almost a rook (Stockfish19) or at least almost a minor piece (Dragon1), whereas capturing on c1 or d1 gives an equal position, according to the engines.

22.Rxc8 Bxc8 23.Nc6+!?

Forced exchanges now bring about an ending in which White has the only endgame piece par-excellence, ie a rook.
23...Ke8 24.Nxe5 Qxd1 25.Rxd1 Bxe5 26.Bf4 f6

Black can save the bishop-pair with 26...Bf4!?, but White has a pleasant choice between pushing on the queenside, or grabbing the g7 pawn, eg 27.Bxg7 f6 28.g3 Be3+ 29.Kg2, and, if 29...Kf7?!, then 30.Rd3, when 30...Bc1? runs into 31.Rc3.

27.Bxe5 Nxe5

White's advantage is roughly the equivalent of being up a minor piece, according to the engines.

28.Kf2 Nc4 29.Rc1 Ba6 30.b3!? Ne5

Not 30...Nxa3? 31.Ra1, but after the text Black threatens a fork with 30...Nd3+, a reminder that even 'simple' endgames can have tactical tricks and traps.
31.Ke3 Kd7 32.Rc5 g5!? 33.g3 h5 34.Ra5 Bb7 35.h3 Kc7 36.f4 Nc6

Not 36...Kb6? 37.fxe5! Kxa5 38.exf6, after which the white pawn queens.

37.Rc5 Kd6 38.Rc3

The engines much prefer 38.b4.

38...e5 39.fxg5 fxg5 40.h4 g4!?

Perhaps hoping to somehow create a queening threat, but it never materialises.

41.b4 Ba6 42.Rc5 Bb7 43.Rd5+ Ke6 44.Rb5 1-0

A somewhat strange time to resign, perhaps, but the engines reckon White's advantage is the equivalent of being up more than a rook and a pawn. A likely continuation was 44...Bc8 45.Rb6 Kd7 46.b5 Nd4 47.a4 Ne6 48.a5 etc.

White's dark-square bishop is bad, but that is outweighed by White's extra space and the slightly awkward posting of the black queen, according to the engines.

4.Bg2 Nc6

So far, so obvious, but how should White continue?

5.e3

This is second in popularity to 5.d3, after which the main line in Mega26 runs 5...Be7 6.Nf3 0-0 7.0-0, with a slight edge for White, according to Stockfish19 and Dragon1.

5...d6

The engines suggest an apparent-novelty in 5...d5!?, the idea being to meet 6.cxd5 with 6...Nb4, when 7.e4 (the engines prefer 7.a3, 7.Nf3 or 7.d3) c4!? 8.Bf1!? b5 gives Black enough compensation for a pawn, according to Stockfish19, although Dragon1 reckons White is slightly better. Nevertheless, although the latter engine sticks with 5...d5!? as its top choice, Stockfish19 fairly quickly comes to prefer the text, or 5...g6.

6.Nge2 Be6 7.d5

More common is 7.b3!?, but that allows 7...d5!?, when the engines agree Black is better.
7...Bxd5!?

This has been played by at least one grandmaster, and scores an excellent 56% in Mega26, albeit from a small sample, but giving up Black's better bishop to go pawn-hunting, before castling, is decidedly double-edged.

8.cxd5 Nb4

How should White proceed?

*****

*****

*****

*****

*****

9.d4!?

This apparent-novelty is Stockfish19's second choice, at least for some time, but the engines agree best is 9.Qb3, when a sample line continues 9...Qb6 10.0-0 Be7 11.Rd1!? 0-0 12.d3!?, with the upper hand for White, according to the engines, but there are many reasonable alternatives along the way.

Leonardo Andrade (2238) - Ľubomír Ftáčnik (2551), Portuguese Team Championship 2010, went 9.0-0 Qd7 10.e4!? Be7 11.a3!? Nd3, with equal chances, according to the engines (0-1, 41 moves).

9...exd4!?

Perhaps Black should take the plunge with 9...Nbxd5!?, although both 10.Qb3 and 10.0-0 are promising.

10.exd4 Qa5?!

This is almost certainly a mistake. The engines suggest 10...Be7, but give White the upper hand.

11.0-0

This is much better than 11.Bd2? Nd3+.

11...Be7

Not 11...Nbxd5? 12.dxc5 Qxc5, when White is spoilt for choice, with several winning moves, including 11.Nf4, 11.Qa4+ and 11.Re1.

12.Bd2 Qc7 13.Rc1

Perhaps even stronger is 13.dxc5 dxc5 14.Nc3.

13...Na6?!

The engines suggest 13...Qd7.

*****

White's bishop-pair, passed pawn and safer king more than outweigh any advantage Black may derive from having a queenside pawn-majority and fewer pawn-islands. The engines reckon White has a positionally won game.

18.Bg5!

Almost certainly not 18.Bh3+?!, as 18...Ke7! greatly reduces White's advantage, since White has difficulties defending d5 at the same time as preserving the bishop-pair.

18...Ne8 19.Bh3+

But now this is good.

19...Kc7 20.Nc3 f6?!

The engines agree with driving away the bishop, but reckon 20...h6 is the better way to do it.

21.Be3

Even stronger, according to the engines, is 21.Nb5+!? Kb6 22.Nxd6 Nxd6, and then Be3.

21...Rd8 22.Rfd1 b6 23.Nb5+ Kb7 24.a3?!

Probably too slow. Best may be 24.Bg2!?, when one line given by the engines runs 24...g5!? 25.a4 Kb8 26.f4!? h6 27.Bd2!?, with what they reckon is at least the upper hand.

24...Bb8?!

Better is 24...Nc7, maintaining the blockade.

How can White take advantage of Black's last move?

25.d6!

Giving up the passed pawn to get at Black's king.

25...Nxd6 26.Bg2+ Kc8 27.Nd4 Nf7!?

This may be best, but the engines also suggest 27...g6 and 27...Rd7.

28.Nc6 Rxd1+ 29.Rxd1 Bd6?!

Perhaps best is 29...c4!? 30.Rd4 Ne5 31.Ne7+ Kc7 32.f4!? Ng4 33.Nd5+ Kc8, but 34.Rxc4+ wins back the sacrificed pawn, with a continuing attack. Note that if Black gets the king's rook into play with 29...Re8, White has 30.Bh3+ and 31.Rd7+.

30.Nxa7+ Kb8 31.Nb5 Rd8!?

This is best, according to the engines, as moving the bishop allows White's rook to occupy the seventh rank.

Two bishops are usually much stronger than a rook, even in an ending, but making progress in this position proves to take a long time. The engines reckon White's advantage is about +4.5.

38.Bf3 Kd6 39.Kf1 b5 40.Bd2 Rb8 41.Bc3 Ke6 42.Bg4+ Ke7 43.Bf5 h6 44.Ke2 Rb6 45.Bd3 c4 46.Bf5 h5 47.Kf3 Kf7 48.Bb4 Rb8 49.Bd7 Rb7 50.Bc6 Rb6 51.Bd5+ Kg6 52.Ke4 Rb8

The move ...d5, without first playing ...d6, is thematic in the Accelerated Dragon, and 8...d5!? here is also the top choice of Stockfish19 and Dragon1.

A main line has yet to be established, it is probably fair to say, but this is the most popular continuation in Mega26, and scores an excellent 64%.

10...Nxb3 11.Nxb3

11.axb3!? has been played, but Black immediately regains the pawn with 11...Nxd5.

11...b6 12.d6!?

The engines agree with giving the pawn back, but saddling Black with an isolani.

12...exd6 13.Qf3 Bg4 14.Qg3 Bh5?!

Apparently a novelty, and almost certainly not a good one. Known moves are 14...Bf5 and 14...Rc8.

15.Bd4

The unsubtle 15.f3!? is also strong.

15...Re8

This is Dragon1's top choice, at least for a while, but better may be 15...h6 16.f3!? g5!?, although the engines reckon 17.f4!? gives White a positionally won game.

16.f3!? Qd7?

Reducing the protection of f6 causes Black big problems. Perhaps best is 16...Rc8!?, and if, as in the game, 17.Qh4, then 17...Rc4, as 18.g4? Rxd4! 19.Nxd4 Nxg4! 20.Qxd8 Bxd4+ 21.Kh1 Rxd8 22.fxg4 Bxg4 23.Rf4 Bxc3 24.bxc3 Bf5 sees Black emerge with two pawns for the exchange, and the much better pawn-structure, the engines reckoning Black would enjoy the upper hand.

The engines prefer 21...Bxc2, when 22.f5 forces Black to give up the exchange with 22...Re5.

White has more space in the centre, but this is of little consequence, according to the engines, presumably because Black is well-placed to get in a quick ...c5, without White being able to push on with d5. The engines reckon the game offers equal chances.

White's extra pawn island, and a lack of meaningful targets for the bishop, mean Black is slightly better, according to Dragon1, although Stockfish19 disagrees.

Played to prevent ...e5, but probably a mistake.

36...Ke7 37.Ke2 Kd6 38.Bb7 Nd5

This is Dragon1's recommendation for quite some time, but Stockfish19 much prefers 38...g4!?, claiming Black is winning. Dragon1 comes to agree 38...g4!? is best, but is far less sure how strong it is.

After 38...g4!?, best play may run 39.Ke3 a5 40.Kd3 Ne8!? 41.Bc8 Nf6 42.Ke3 Nh5 43.Kf2 Kd5 44.b3 Kd6!? 45.Bb7 Nf6 46.Ke3, when the engines are enthusiastic about Black's chances, but it is not clear how Black makes progress.

1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.a4!?

A relatively rare continuation, featuring in just 427 out of 24,360 games in ChessBase's 2026 Maga database, ie 1.75% of the time, but it is marginally the top choice of Stockfish19, so can be expected to become more popular.

How should Black respond?

5...b6

The main line in Mega26 runs 5...e6 6.e5!? d6 7.Bb5 Nge7 8.Ne4!? dxe5 9.fxe5 0-0 10.Nf6+ Kh8 11.d4!?, with a slight edge for White, according to Stockfish19, although Dragon1 is less sure.

6.Bc4 Bb7 7.0-0 Nd4 8.d3 e6

The engines agree this apparent-novelty is an improvement over the known 8...Nxf3+.

The position after 8...e6 occurs twice in Mega26, but in each case with Black to move, White having played Bb5, before dropping the bishop back to c4

9.Nb5 d6?

Black should play 9...Nxb5!?, according to the engines, despite 10.axb5 giving White pressure against a7. After the text, the engines reckon White has a positional advantage worth at least a minor piece.

10.Nbxd4

Also very strong are 10.Nfxd4 and 10.f5!?

10...cxd4 11.Bb5+

This natural move leaves White winning, but seemingly even stronger is the engines' 11.f5!?

11...Kf8 12.Bc4?!

This throws away much of White's advantage, which would be preserved by moves such as 12.a5 and 12.Qe1, according to the engines.

12...Ne7?!

12...d5 is much preferred by the engines.

13.Qe2 Rc8 14.Bb3!?

This is the engines' top choice, marginally ahead of 14.Bd2.

14...h6!? 15.Qf2 Nc6?

Counterplay with 15...d5!? is the engines' preference.

16.f5!

White's advantage is worth a rook (Stockfish19), or at least more than a minor piece (Dragon1)

18.Nh4?

Black has no defence to 18.f6! Qxf6 19.Qg3, eg 19...Rc7 20.Nh4 Qd8 21.Ng6+!

18...Bf6

An only-move, but good enough for equality.

19.Ng6+??

White has to play 19.Nf3.

19...fxg6 20.fxg6 Kg7

The black king is more vulnerable than White's, but the g6 pawn acts as a shield, and White's attack is not worth a piece

21.Qf5 Qe7 22.Bd2 Rcf8 23.Bf7!? Nd8 24.Qg4 Bc8!?

Not the only solution, but arguably the simplest.

25.Qxc8 Nxf7 26.Qf5 Nd8!? 27.Qe4 Qe8 28.Rf3 Bg5

Not 28...Qxg6?? 29.Rg3 Bg5 30.Qxg6+ Kxg6 31.h4.

29.Bxg5 hxg5 30.Raf1 Rxf3 31.Rxf3 Rf8 0-1

League Chess

PLAYED on board three (of five) for Battersea Galacticos against Wanstead in Central London League Division Two last night.

Mark Murrell (1838) - Spanton (1955)

Colle System

1.d4 d5 2.e3 Nf6 3.Bd3 Nc6!?

There are 1,066 examples of this move in ChessBase's 2026 Mega database, but it lags in popularity behind 3...c5 and especially 3...e6. After the text, White can choose between continuing Colle-style with 4.Nf3, or making the opening a Stonewall Attack with 4.f4.

4.Nf3 Nb4!?

This is the top choice of Stockfish19 and Dragon1.

How should White respond?

5.0-0!?

The main line, albeit from a small sample size, runs 5.Be2 Bf5 6.Na3, with equal chances, according to the engines.

5...Nxd3 6.Qxd3

Black has won the bishop-pair, but it has cost two tempi (...Nb4 and ...Nxd3), which White has used to castle and develop the queen

*****

*****

Database analysis by international master - now grandmaster - Larry Kaufman shows the bishop-pair is worth, on average, half a pawn, while it is generally accepted a pawn in the opening is worth three tempi (sometimes 2.5 tempi are quoted, or even "two-three" tempi). This suggests that, all other things being equal, Black's bishop-exchanging manoeuvre is not quite worth it. However, the engines reckon the position is equal, and it may be that the passive 2.e3 is responsible for all other things not being equal.

6...c6!?

Apparently a novelty. The engines reckon it is roughly equivalent to the known 6...a6, but better than the other known move, 6...Bg4!?, when 7.Ne5 and 7.Qb5+ are both promising.

7.Nbd2 e6 8.e4 dxe4 9.Nxe4 Nxe4 10.Qxe4 Qd5 11.Qxd5

Exchanging queens helps Black, according to the engines. They suggest 11.Qe2 Bd6 12.c4.

11...cxd5 12.Bf4 Be7 13.Rfc1!?

This is Dragon1's top choice, at least for a while, and comes to be also liked by Stockfish19.

13...Bd7 14.Ne5 b5!? 15.a4 b4

The engines prefer 15...bxa4 or 15...a6!?

16.Nxd7 Kxd7 17.c4 dxc4

The engines reckon 17...Rac8!? gives Black a slight edge, despite allowing White to create a protected passed pawn with 18.c5, when the engines continue 18...g5!? 19.Bg3 h5 20.h3 Bf6 21.Rd1, with ...Kc6 to come to blockade the passer.

18.Rxc4 Rhc8 19.Rac1 Rxc4 20.Rxc4 Rc8 21.Rxc8 Kxc8

How would you assess this bishop-and-pawn ending?

*****

*****

*****

*****

White has an extra pawn-island, but the position is completely equal, according to the engines.

22.b3 Bf6 23.Be3 Kb7

White gets a slight edge, or at least the better part of equality, after 23...Kc7 24.d5!?, according to Dragon1, but Stockfish19 disagrees.

24.Kf1 a6 25.Ke2 Kc6 26.g4!? Kd5 27.Kd3 h6 28.f3 Bg5!? 29.Bf2

Not 29.Bxg5? hxg5, eg 30.Ke3 a5 31.Kd3 f6!? (31...f5? 32.gxf5 exf5 33.Ke3 is equal) 32.Ke3 f5 33.gxf5 exf5 34.Kd3 f4!, after which d4 drops. Note that in the bracketed line, if Black continues 33...f4+, then 34.Kd3 g6 35.h3 is drawn as long as Black finds 35...g4! 36.hxg4 (36.fxg4? g5 wins for Black) g5, eg 37.Ke2 Kxd4 38.Kd2.

29...Bf4 30.h4 f5 31.h5 Bg5 32.Be1 a5?

32...Be7 holds, as does 32...gxf4 33.gxf4 Be7 (or 33...Bf6). The text leaves too many Black pawns on the same colour complex as the bishops.

33.Bg3 gxf4

Or 33...f4 34.Bh2 Bf6 35.Bxf4 Bxd4 36.Bc7.

34.gxf4 Bf6 35.Bf2 ½–½

White wins with 35.Bc7 Bxd4 36.Bxa5, a possible continuation being 36...Bc5 37.Bc7 e5 38.a5 e4+ 39.Ke2 Bd4 40.Bb6 Bxb6 41.axb6 Kc6 42.Ke3 Kxb6 43.Kxe4 Kc6 44.Kd4 Kb5 45.Kd5 Kb6 46.Kc4 Ka5 47.Kc5, etc.

However, the text spoils nothing (White's advantage is roughly the equivalent of being a rook up after 35.Bf2, according to the engines, although Dragon1 has to be shown some of the lines to change its evaluation from completely equal), but offering a draw did.

Black cannot stop White's plan even after 35.Bf2, eg 35...Be7 36.Bg3 Bd6 37.Bh4 Bc7 38.Be7 e5 39.Bf8! exd4 40.Bxg7 Bf4 41.Bxd4, with an easy win.

Battersea Galacticos won the match 3.5-1.5.

El Chess

AM making final preparations for flying to Spain tomorrow for the fourth Cap Negret seniors' congress on the Costa Blanca.

I have entered the 65+, which has 130 entries, including a grandmaster and two international masters. There is also a 50+, with 44 entries.

There are nine rounds over eight days, so I have booked a halfpoint bye in the first game of the double-round day. Six of the rounds start at 16:30; three at 10:00.

The time control is 90 minutes, with a 30-second increment throughout, and the rules show the prize money to be the same in each tournament, despite the discrepancy in numbers.
