KEG: Post II
11. g5!
Having played 9. g4, it was too late for von Gottschall to back down now. 11... NxB
Challenge accepted. Jacob could have chosen the defensive 11...Nd7. The position with von Gottschall (White) to recapture was:  click for larger viewThe obvious--and correct--recapture was 12. axN. von Gottschall, however, decided to stake all on his King-side attack and tried something even Tahl would have passed up (because it loses: 12. gxN?
While von Gottschall ultimately won this game, this is simply zany. The position was now:  click for larger view12... Nd4?
Huh? As DanRoss53, WannaBe, and Straclonoor have ably shown on this site, Black should have played the obvious 12...NxR. This wins (following WannaBe's line): 13. fxg7 (Straclonoor has shown that White also loses after 13. Bg5) Kxg7 14. Bd2 b4 15. Na4 Nxc2+ (15...Ba7 is even stronger than WannaBe's 15...Nxc2+). If 13. a3 Black wins after 13...d5 14. fxg7 Kxg7 15. Bd2 dxe4 16. Nxe4 BxN 17. dxB Qd6. Incredibly, the only alternative to 12...Nd4? discussed in the Tournament Book is 12...NxB. While 12...NxB is better than the text, it probably blows the win--especially on the badly flawed line appearing in the Tournament Book: 12...NxB 13. fxg7 Kxg7 (13...Nd3+ is much stronger and retains some winning chances) 14. QxN Qf6 (Black can retain some edge with 14...b4 or 14...Rg8). 15. h4 with roughly equal chances. This was very poor analysis in the Tournament Book (which did a better job with the complications what arose on move 17). After 12...Nd4?, the position was:

With the simple 13. fxg7, von Gottschall would have had about equal chances. But now, he was back in trouble. 13... Re8!
The best way to anticipate the coming King-side attack. 14. h4?!
von Gottschall had to get his h1 Rook on the g-file. Since the Black Bishop on c5 precluded 14. Rg1, he had to play 14. Rh2. The text (14. h4?!) was over the top, and von Gottschall was in trouble once again. 14... gxf6
15. NxN
15. Bh6 was probably better, but von Gottschall would still have been on the ropes with best play by Black. The position, with Jacob to recapture, was now:

Ke2 d5 leaving Black two pawns up and White's attack nearly at an end. But instead of the seemingly obvious 15...exN, Jacob inexplicably played: 15... BxN?
Now, it was Jacob who was at risk of loss, the position now being:  click for larger viewAs I will discuss in my next post on this game, von Gottschall's attack now picked up steam, until he wgain went astray on move 17. In fairness to the players, they were confronting the tricky tactical possibilities while I have spent hours examining the game with computer assistance as and when I thought I required it. But some of the moves missed (e.g., 12...BxR amd 15...exN) were hardly very difficult to find. |
