Catastrophe In The Opening

LOST badly today to a junior in round three of the Benidorm U2000.
Alejandro Garcia Oviedo (1811) - Spanton (1940)
Giuoco Piano
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.e5
This is much less popular than 6.cxd4, but it scores better in ChessBase's 2019 Mega database.
6...d5 7.Bb5 Ne4 8.cxd4 Bb6
This has been recommended by grandmaster Victor Bologan.
Almost as popular, but not scoring so well, is 8...Bb4+.
9.Nc3 0-0 10.h3!?
The main move is 10.Be3.
The text is a minor sideline that has grown in popularity in the last two years and scores very well for White.
Note that 10.Nxe4? is bad because the d4 pawn cannot be saved after 10...dxe4.
Position after White's little-played but worth-investigating 10.h3!?
10...f6
I took a long look at 10...Nxd4? 11.Nxd4 Nxf2 12.Kxf2 Qh4+ but gave it up because of 13.Ke3? But Stockfish9 points out 13...Bxd4+ 14.Qxd4 Qg3+ 15.Kd2 Qg2+ with a very murky position.
However, the engine improves in a big way by giving back one of the knights with 13.Kf3!, when 13...Qxd4 allows White to exchange queens, while 13...Bxd4?? loses to 14.g3.
11.0-0 Nxc3?
I rejected the obvious 11...fxe5 because of 12.Nxe4? (White should play 12.Bxc6, with equal chances) dxe4 13.Ng5, but 13...Qe7 is simple and good.
12.bxc3 fxe5 13.Bxc6! bxc6 14.Nxe5
Black has the bishop-pair but has to act urgently to prevent being much worse
Black's bishops provide decent compensation for his inferior queenside pawn-structure.
But White has kingside attacking chances thanks to his kingside pawn-majority and the magnificent knight at e5. Meanwhile, Black's dark-square bishop is in danger of being completely shut out of the action.
14...Qf6?
Playing for an attack on f2 that White is easily able to nip in the bud.
I rejected the superior 14...c5 because of 15.Ba3, missing that 15...Re8 indirectly saves the c5 pawn by targeting the knight. Even so, White is still significantly better.
15.Ba3 Re8 16.f4
White duly got his kingside attack and won rather easily in 30 moves.

Catastrophe In The Opening

IAKOV Neishtadt compiled Catastrophe In The Opening, which appeared originally in Russian before being published in English by Pergamon Press in 1980.
It highlighted "mistakes … committed in the initial stages of a game … which determine its outcome."
That neatly summarises my game on board two tonight for Battersea 3 in the second division of the Central London League against King's College.
Spanton (167) - Garik Mirzoyan (165)
Owen's Defence
1.e4 b6 2.d4 Bb7 3.Nc3 e6 4.Bd3 d5!?
An unusual continuation, and one that has not attracted the attention of strong players.
Most popular, at least in ChessBase's 2018 Mega database, is 4...Bb4, while John Owen, after whom the defence is named, chose 4...Nf6 in a loss to Blackburne in 1890 (28 years earlier Blackburne had played 4...g6 in a match-game loss to Steinitz).
5.exd5
The other 'obvious' move is 5.e5, but setting up a centre for Black to attack, initially with 5...c5, scores very poorly for White.
The idea of the text is to block Black's light-squared bishop (or gain the bishop-pair in the event of 5...Bxd5).
5...exd5 6.Nf3 Nf6 7.0-0 Be7 8.Re1
All 14 games in Mega18 saw 8...0-0, but my opponent chose a "catastrophe"
8...Nbd7??
Perhaps the plan was to unbalance the position by castling queenside, but after …
9.Qe2
… Black is already positionally lost.
9...c5
I thought afterwards that Black should have tried 9...Nf8, but my main analysis engines, Stockfish9 and Komodo9, give the simple 10.Bf5, when Black still cannot castle anytime soon.
10.Bf4 Kf8
This is the engines' top choice, but that only shows how bad Black's position is (1-0, 29 moves).
MY Battersea unbeaten streak has now reached 14 games.
