KEG: Post III
In the position with which I ended my last post, Pillsbury recognized and carried out a fascinating--and decisive--plan. He reduced the game to an ending in which he was effectively a piece ahead because of hopelessly blocked Black Bishop. 18. BxN
18. Ng5 would probably also have won, but having identified a winning plan Pillsbury was not to be distracted. 18... gxB
19. Nh4
Karpov would perhaps have been delighted to tie up Black with 19. c4, but Pillsbury's winning plan was probably just as effective. White could probably also win here with 19. RxR and then 20. c4. 19... b5
Bardeleben apparently saw what was coming, and decided to take counter-measures with a Queen-side demonstration. This plan did not have a great chance of success, especially against Pillsbury, but some form of counter-attack was Bardeleben's only conceivable chance. 20. Qf5
20. RxR followed by 21. Nf5 and 20. Nf5 immediately both seem to win quickly. Objectively, these moves were better than 20. Qf5. But it is hard to fault Pillsbury for a plan that--though not the fastest route to victory--certainly seems sufficient. 20... QxQ
The ending held little hope for Bardeleben, but everything else was worse. 21. NxQ
This left the following endgame for the contestants to contemplate:  click for larger viewIn a classic understatement, Sergeant-Watts stated that: "After the exchange of Queens the Black Bishop remains shut in." In fact, Bardeleben's Bishop was not just bad, it was utterly useless. 21... Reb8
21...Rec8 was perhaps slightly better, though still leaving Black hopelessly constricted. 22. h4
"!"--Tournament Book.
Pillsbury is playing to advance his h-pawn to h5 and, if allowed, to h6. 22. Rf3 was seemingly a faster way to win. 22... a5
Continuing with his Queen-side build-up. But 22...Rc8 or 22...c4 were more forceful and better ways to pursue this plan. 23. h5!
23. Rf3 was also good. But Pillsbury throughout this game was relentless in pursuing his plan. 23... h6
"!"--Tournament Book and Sergeant Watts.
"h6 must be stopped" (Sergeant-Watts)."
If Black is willing to endure a White pawn on h6, he might try 23...a4 or 23...Rc8 to continue his own counter-attack. An unpleasant choice of poisons for Bardeleben. 24. Rf3
Reading himself to pound on the g-file.
24... a4!
One must admire Bardeleben's spunk in his difficult position, which now was:  click for larger view25. Kh2
He could just have played 25. Rg3+, but Pillsbury was in no hurry and decided to eliminate any risks from counter-play. 25... axb3
The plan to attack on the a-file was almost certainly futile, but passive defense with something like 25...Rc8 would not have been much better. 26. axb3 Ra2
This incursion with the Black Rook was less dangerous than it may appear on first glance. 27. Re2
Pillsbury could have equally well preceded this move with 27. Rg3+ The position was now:
