Ra-g8 is a fine move and made at the perfect time (in my opinion). White's pieces (especially the N on b5) are not well-placed for a defence on the K-side, and white has not yet begun a pawn push on the Q-side. To delay is not wise. After grabbing the P the WN is badly out of play. [D]6rk/N2bq3/np1p1brn/2pPp1pp/1PP1Pp2/P2Q1P1P/1R3NP1/3BBRK1 b - - 0 27 Speaking only from the perspective of a human player, here I think 27 .. Q-h7 (or after 27 .. g4 as actually played) and black is fine even against strong computers. After his K-side pawn push, the h-file is forced open and then BQ can eventually occupy h4 or h3. White may have to fight for the draw. In the game played, I think Kasimdzhanov misplaced the Q on the g-file on move 29. Its place is on the h-file (h7), or maybe on f6 to menace h4. But even after this inaccuracy, black had equality, up to this point IMO- [D]6rk/6q1/npNp2r1/2pPp2b/1PP1PR1b/P1B4P/1R4P1/5QK1 b - - 0 34 Now all black has to do is retreat with 34 .. B-f6 (obviously not e7 or d8 else white can exchange his compromised knight), and next move correct his error (from move 29) and put the Q on the h-file. White is in a bind, and can only draw this. But unfortunately Kasimdzhanov blundered here with 34 .. B-g3?, at which point it is 1-0 in my opinion. HE ALLOWED THE WR TO ENTER HIS 7th RANK BY THIS BLUNDER!! And also activate the Q-side WN! [D]6rk/6q1/npNp2r1/2pPp2b/1PP1PR2/P1B3bP/1R4P1/5QK1 w - - 0 35 Hydra of course found 35 R-f7, and now the human could safely resign. I don't have the moves after 36 B-d2 but I would predict Hydra will exchange and push a pawn storm through, with its R on the 7th it has nothing to fear on the K-side. Now please set it up with the programs and show me I am wrong in my human overview. Uri, given that K. was not able to handle the tactics properly, you too are also right that he should have avoided them by keeping his R on the a-file. :) -A.S.
