visayanbraindoctor: After 15...Nxe5, Black has castled, has a Knight and a pawn in the center, occupies the half open f-file and is ready to develop his Bishop out and occupy the open e-file.
White has not castled and his Knight is on the first rank.
16. O-O Nxd3 17. cxd3
In this position, a spectator might ask, 'How can a strong player like Eliskases lose with Black in this one?'
Eliskases then makes what looks like a totally logical move that fixes White's pawn on d3, making it a target or his now 'good' Bishop.
Then he proceeds to occupy the e-file, an d target the White d-pawn.
17.cxd3 d4 18.f3 Re8 19.Nf2 Re3
But that may have been a mistake. Lasker typically counter punches by occupying the c-file and attacking Black's advanced pawn on d4.
20. Rac1 c6 21. Rc4 Be6 22. Rxd4
Thus a more conservative move like 19.. c6 at once may have been better.
But it's clear that Eliskases has overestimated his position. He must have gone into this line already aiming to attack White's Queenside pawns and create what may have looked to him a winning Queen side majority, after
But this line gives up the 7th rank.
Eliskases continues with his plan, advancing his Queen side pawns, and moving back his bishop to make way for more potential advances.
b5 24.Ne4 Bd5
Eliskases still proceeds aggressively, trying to eat up White's remaining Queen side pawn
Not sure of the soundness of his plan. Lasker again counter punches, by abandoning his b-pawn and concocting a plan that would enable him to seize the 7th rank. He takes advantage of a tactical shot- a fork of Black's B and R by Nc3.
26.Nc3 Rxb2 27.Nxd5 cxd5 28.Rc1 Kh8 29.Rcc7
So I think
may have been a mistake.
Not sure what Black should do by now. Eliskases' whole plan was THE mistake. It allowed Lasker to dominate the 7th rank with his Rooks.
Note again how Lasker demonstrates his counter punching style. It is games like this that probably contributed to his legend of being able to magic his way from an inferior position to a draw or win. Lasker does NOT do passive defense. He is always on the look out for counter offensives, and in this case he spotted a way to bring his Rooks to the 7th rank, at the cost of sacrificing his Queenside pawns. But that's alright, he won the game. The best defense is a good offense.
