Dec-19-08  number 23 NBer: I had thought that ♖♙♙ vs. ♖ was drawn with f- and h-pawns. Did white make a mistake here? If so, what was it?

  whiteshark: Bogo had to win this game to share 1st-2nd place with Zemgalis.

White has already played Kh3 twice (on moves 101 & 108) and it would have been a good move here too: 111 Kh3. If White wished to move his Rook, then a8 is a good square because he can then check laterally. There was no sense in 111 Rf8 since it invited 111..Kf3! and after 112 Ra8 (112 Kh3 f4) 112..f4 113 Ra3+ Kg4 114 Ra4 h4 Black is making progress.

But Bogo didn't take his opportunity and went 111..Kg4. The players reached this position:

White can't go Kh3 anymore so swinging the Rook over would have been natural: 114 Ra8 f4 115 Rb8 f3+ 116 Kf2 or 115..h3+ 116 Kh2 holding. Instead, Heemsooth mved his King to the side: 114 Kh2 and now after 114..f4 115 Ra8 is too late 115..Rb7 116 Rg8+ Kf3 117 Kh3 Rb1 118 Kh2 Ke3

But the game continued as Bogo opted instead to put his Rook off-side: 114..Rg5? Now Heemsoth should have back-tracked with Kg2 but instead he plonked his Rook on the same dubious f8 square as before: 115 Rf8?

The game still wasn't over! The winning plan still involves getting ..Kf3 in and 116..Rb5 was a good way to force the issue. But this time Bogo chose 116..h3 when to draw White just needed to play a waiting move like 117 Rb8. Instead he threatened h3 with 117 Ra3? allowing Bogo to re-activate his Rook with 117..Re5.
