Lasker was a great player, one of the best ever!

Pillsbury – Lasker [Game 41, p. 132ff]
St Petersburg (4), 29.07.1896

Position after 27...Kg8-h7


Here Pillsbury played 28.Kxa3?? Kasparov writes: "For some reason no one has pointed out the saving 28.Qf5+! 28...Kh8 29.Kb1! Rxa2! (29...Bxd4 30.Qf8+ Kh7 31.Qxa3) 30.Rxa2 Qb3+ 31.Kc1 Bg5+ (31...Qxa2 32.Qc8+ Kh7 33.Qc2+) 32.Rad2 Qc3+ 33.Qc2 Qa1+ 34.Qb1 Qc3+ with a perpetual check."

However Sorokhtin gives a winning line for Black: 28.Qf5+ Kg8 29.Kb1 (29.Qe6+ Kh8 30.Qe8+ Kh7 31.Kb1 Bxd4 32.Qe2 Qb4+ 33.Rb2 Bxb2 34.Qxb2 Qe4+ 35.Ka1 Ra6–+) 29...Bxd4 30.Re1 Qb4+ 31.Kc1 Qc3+ 32.Qc2 Qa1+ 33.Qb1 Rc3+ 34.Rc2 Be3+ 35.Rxe3 Qxb1+ 36.Kxb1 Rxe3 37.Rd2 Re5–+.

Karsten Müller: Sorokhtin's analysis shows that 27...Kg8-h7 does indeed win and so deserves an exclamation mark.

So Black wins in all in all key lines! Lasker's Greatest Masterpiece and maybe the greatest Combination in Chess History!!

Hi Terry,
I also wrote about this game and Kasparov's (mistaken) comment in my book:
Robin Smith - [u]Modern Chess Analysis[/u] wrote: 28.Kxa3
In his book, Kasparov gives this move a double-question mark and writes "for some reason no one has pointed out the saving 28.Qf5+!", but after 28...Kg8! (Kasparov gives only the inferior 28...Kh8? 29.Kb1=), 29.Qe6+ Kh8! leads us back into the note to Black's 27th move, while if 29.Kb1 Bxd4! Black still wins. Probably Kasparov was trusting his computers too much here. Many programs see only a 0.00 evaluation, but this is merely an artifact of these programs knowing White can repeat the position with 29.Qe6+. Yet Black is under no obligation to repeat, and could instead correct his move 27 inaccuracy.

Excellent! You should submit this information to ChessBase if you found it first.

I agree that Kasparov was trying to review too many games using computers as an assist to get published as quickly as possible.

Best,

Pillsbury got his revenge against Lasker at Cambridge Springs in 1904. Another great game. :!:

p.s. I'd love to see Lasker, "the apostle of common-sense," play a match against one of the top engines. Of course, I live in a dream world... :lol:

Well, Lasker predicted that chess could be solved mathematically, he would be impressed to see how far his vision has come!

The Chessbase article is from 2004 and my book was printed in 2004, so I don't really know (nor care) who was first. I do know that we both came to the conclusion that Kasparov's analysis of that game was wrong in spots independently of each other. I just thought it interesting that the most likely cause for Kasparov's error in this case was incorrect use of computers as analysis aids.

Regardless, it's no mean accomplishment!

Kudos,
