Mar-12-05  blackpawnther: wow awesome game. i like 22.Bxe5 cause black cant take unless he wants serious adding this to my favorite games.
Jul-30-05  flor: beautiful attacking game.

Analysis from Fritz 8: Early on in the game, the computer comes up with this alternative for black: 15. ... axb3
16. axb3 Ra2
17. Bc3 Qg4
Qg4 defends the kingside and pins the knight. White's plan to Ng5-Qg4 has been stopped. 18. hxg6 hxg6

with about equal game, still according to Fritz.

Sep-16-13  computer chess guy: 25. Rd5 is quite a spectacular move, but it was better to play immediately 25. Be6!! - in fact this is a forced mate:

Analysis by Houdini 3 w32:

1. (#19): 25.Be6 Qc5+ 26.Kh1 Rxd1 27.Rxd1 Rc8 28.Bxc8 Qb5 29.Bxf6 Bxf6 30.Rd8+ Qe8 31.Qh6+ Bg7 32.Nh7+ Kf7 33.Be6+ Bxe6 34.Ng5+ Kf8 35.Nxe6+ Kf7 36.Qxg7+ Kxe6 37.Rxe8 Kd6 38.Rxe7 Kc6 39.Rxc7+ Kb5 40.c4+ Ka5 41.Qe5+ Kb4 42.Qb2+ Ka5 43.Qb5#

Also after 25. Rd5, Houdini indicates Black actually had an escape via the move 26. .. Rd7!:

Taking the Rook is not good: Bxd7 Qxd7 and Black is at least temporarily safe and threatens the White Rook, Knight and Bishop.

Mar-25-18  Olavi: <Also after 25. Rd5, Houdini indicates Black actually had an escape via the move 26. .. Rd7!:>

This was indicated by Polugaevsky in Grandmaster Performance. (27.Rf2!? or 27.Qg8+)

25.Rd5 he punctuates !!?? After 25.Be6 he gives 25...Qc5+ 26.Kh2 Bxf1, but gives the impression that black survives (not only mate-wise). Instead he recommends 25.Bxf6 Bxf6 26.Rd5. (The same a move earlier, 24.Bxf6)
