KEG: Post II
15. f4?!
Here comes Pillsbury!
Like <Pawn Ambush> I admire Pillsbury's f4-f5 here, but there were many other (albeit less violent ) ways to go after Black here (e.g., 15. Qe4; 15. Rfd1; 15. c4; etc. 15... g6
Rather than immediately weakening his King-side, Gunsberg might have tried for counter-play with 15...b6 or maybe 15...a5. But the text was certainly understandable and definitely not a serious mistake. After 15...g6, the position was:

One way to go after the Black King. I might have expected 16. g4 from Pillsbury, but the text worked out fine for him. 16... Bg7
Perhaps better to play for action on the Queens-side with 16...b6 or 16...a5. The text was also the beginning of a bad plan by Gunsberg. 17. Raf1
Meanwhile, Pillsbury was going all in on the f-file. Other methods might be theoretically better, but it is hard to disagree with <tamar> that Gunsberg probably was shaken when Pillsbury commenced his f-file advance. 17... f6
Sergeant-Watts condemned this as a weakening move. But, Gunsberg's real mistake came one move later. 18. Nd3

Burying his head in the sand and ignoring the threat was a recipe for disaster. Gunsberg had to try 18...f5, or maybe 18...Re8. 19. f5!
"!"--(Sergeant-Watts)(<tamar>)  click for larger viewAs Bobby Fischer would have said: Black is busted. But it didn't prove to be as simple as it should have. 19... gxf5
As Sergeant-Watts pointed out, 19...exf5 loses a piece after 20. Nf4! 20. Rh3
20. Rg3 also wins. But the text was even stronger. 20... Rf7
20...Qe8 was probably best, but neither that nor the text should have allowed Gunsberg to survive much longer. 21. Qh5!
 click for larger viewThe game looks over. "Best" for Black now was 21...Kf8, but Black would soon be wiped out after 22. Qxh7. So Gunsberg tried something else...a blunder that prompted Pillsbury to try to overreach: 21... Bf8?
 click for larger viewThe win for White now looks almost too simple: 22. Rff3 (e.g., 22...Bd6 23. Ne5 BxN 24. dxB Qc7 25. BxN exB 26. exf6 and Black is helpless. But in the above-diagrammed position, Pillsbury became seduced by what looked like a brilliant Rook sacrifice that even sophisticated commentators such as Sergeant-Watts though was the correct winning line but which <tamar> on this site has demonstrated should have allowed Gunsberg to escape with a draw. |
