KEG: Post III
27. Rxf7
Gunsberg's plan was to gobble as many pawns as possible and try to draw with Rook against Rook and Knight. Not a plan likely to be crowned with success, but there was nothing better to try. 27... Rb7
Simpler is 27...Re2 28. Rxg7 Rxe3 29. Rxg6 Re1+ 30. Kh2 Nxc5 31. f5 Rxe5 32. fxe6 Nxe6 after which Black's sole remaining pawn is sufficient to carry the day, e.g., 33. Rg3 d4 34. Rd3 Re2 35. h5 Kd5. But Teichmann preferred to place Gunsberg in the dilemma of either trading Rooks (leading to a lost Knight versus pawns ending) or what in fact followed, the position now being:  click for larger view28. Rf8
Trading Rooks might have been somewhat better, but White seems dead lost in either case (e.g., 28. RxR KxR 29. g4 Nc3 30. Kf2 Nxa2). 28... Nxc5
29. Rc8+
Gunsberg might have gone for broke with with 29. a4 or 29. h4 or 29. g4. But nothing seems to help. 29... Kb5
30. Kf2
This looks like the lamest of his options. But given the 30-move time limit, Gunsberg may have faced time pressure. Viewed objectively, 30. a4+ looks like the best (though likely futile) hope. 30... Ra7
31. a3 Kc4
32. a4
 click for larger viewThe a-pawn leads a charmed life for the balance of the game, and Gunsberg played it for all it was worth. But Teichmann soon proved this was not sufficient and repeatedly declined to pick off this little isolani. 32... Rf7
32...Rxa4 certainly seems fastest. But Teichmann had his own ideas, and never gave Gunsberg any real chances 33. h4 d4
33...Ra7 followed by snatching the a-pawn still seems best, but Teichmann's idea also worked, the position now being:  click for larger view34. exd4 Rxf4+
35. Kg3 Rxd4
 click for larger viewWith the removal of his central pawn mass, Gunsberg might have called it a day. But he still had that a-pawn, and so continued the struggle for a while. 36. a5 Kd5
37. Rc7
If he wanted to continue, Gunsberg might have tried 37. Rg8 37... Ne4+
37...g5 looks to be the more direct route (e.g., 37...g5 38. hxg5 g6 39. Rg7 Ra4 40. Rxg6 Kxe5 41. Rh6 Rxa5 42. g6 Ra3+ 43. Kg4 Ne4 44. Rh5+ Kf6). But the text also wins without all that much difficulty. 38. Kf4 Nf6+
39. Kf3 Kxe5
 click for larger view40. Rxg7
He might as well have tried 40. a6, though aftwr 40...Rxh4 41. Rc5+ Kd6 42. Ra5 Rh8 White would be out of useful ideas. 40... Kxf5
He could also just have played 40...Rxh4
41. a6 Rxh4
42. a7 Ra4
0-1
