Lasker's Spanish Inquisition (part four)

THIS game seems to have been part of a simultaneous exhibition in the City of London given when the world champion toured the UK in 1908.
Emanuel Lasker - CE Wood
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4 Bc5!? 8.Be3 Nf6!? 9.f3
For Alekhine's disparaging comments on Black's last two moves, albeit played in the reverse order, see https://beauchess.blogspot.com/2019/06/uncork-bubbly.html
9...0-0 10.Nd2
The most-popular move in ChessBase's 2020 Mega database, but Alekhine preferred 10.Nf5!?, commenting: "Of course!"
10...Bb6
Capablanca played the more-popular 10...Re8 six years later in a game that ended in a draw.
11.Nc4

How should Black meet the threat to his dark-square bishop?

11...Re8?!
11...Ba7 preserves the bishop-pair, at least in the short-term. However in Spanton (168) - David Rowson (183), London Summer League 2019, there followed the novelty 12.Ne2 (not 12.Nf5?? Bxf5 13.exf5 Rfe8 14.Kf2 Rxe3 15.Nxe3 Nd5 16.Rhe1 Re8), when, with 12...Bb8, 12...b6 and 12...c5 all being unpalatable, Black played 12...Bxe3, getting a position that older engines tend to regard as level, but which Stockfish10 and Komodo10, rightly in my view, regard as better for White (1-0, 52 moves).
12.Nxb6 cxb6 13.0-0-0 c5 14.Ne2 Be6 15.Nc3 Rac8 16.Rd6 b5 17.Rhd1 h6 18.Kb1 Kh7 19.Ne2 b4 20.Nc1 Rc7 21.Nd3 Nd7 22.Nf4 Ne5 23.Nxe6 fxe6
After some middlegame manoeuvring, Lasker has engineered a position in which he has two active rooks and a bishop versus two passive rooks and a knight (it is unusual for White to end up with the sole bishop in an Exchange Spanish, but this was not the only time it was to happen to Lasker). There are many ways to continue, eg Stockfish10 and Komodo10 show White can win a pawn with 24.Bf4 Nc4 25.Rxe6! But this game was part of a simul, and it maybe Lasker relaxed his guard here …
24.Rd8? Rxd8 25.Rxd8 Rd7 26.Rxd7 Nxd7
Perhaps Lasker missed that all the rooks come off because Black threatens a back-rank mate, or it is possible he misjudged the bishop-v-knight ending.
27.Kc1 b5 28.Kd2 Kg6
There are rival pawn-majorities, which normally favours the bishop, but here it is difficult for White to create a passed pawn, but at least he should be in no danger of losing.
29.Bf4
Possibly Komodo10's 29.f4!? is better.
29...e5!?
Now the bishop has two targets (e5 and c5), but the knight easily defends them.
30.Bg3 Kf6 31.f4 exf4 32.Bxf4 Kxe6 33.Ke3 Ne5 34.Bxe5??
A familiar concept. The stronger player sees other moves lead to a dead-draw, so he makes one more attempt to change the balance, only to turn a draw into a loss.
34..Kxe5 35.b3 ½–½
Lasker presumably offered the draw, having belatedly realised it is White's king, not Black's, that will have to withdraw. The point is Black has loads of reserve tempi, while White's soon run out, eg 35...g5 36.g4 c4 37.h3 a5 etc. A lucky escape.
