Jan-21-07  ReikiMaster: 23.f5! protects Ne3 and forces black to open g-file. This makes 24.Ra7 much more powerful.
Jan-21-07  WickedPawn: Got 23. f5 almost immedately but couldn't follow up with the whole combination. I don't expect anything on a Sunday, so I'm glad to say the least.
Jan-21-07  think: More exclamation points in the last 6 moves than I see in entire games of mine. Wow.
Jan-21-07  chessmoron: 23. f5 was a easy one but had a difficult time finding Ra7...but got it about a minute or too but couldn't see the continuation. Oh well, I'll be anxious of waiting for Monday night puzzles.

  An Englishman: Good Evening: Typical me--I saw the speculative pawn sacrifice 23.f5,gxf5; 24.Nxd5,Nxd5; 25.Bxd5,exd5; 26.Nf4,dxe5; 27.Rxe5 and decided that White had good play for the pawn. Didn't see the winning combination at all.
Jan-21-07  Fisheremon: In the case 23...Nxe3 24.fxg6 hxg6 my solution is different from Ivanchuk's:

25.Ra7, here two best Black's replies 25...Bd7, 25...Nd7. In both:

26.Qxg6+ Kh8 27.Be4 Nf5 28.Nf4 with nice attack. I'll come back with more details soon.

Jan-21-07  Cuellargacharna: What's the rebuttal to ...29Bb7?
Good morning. Too long of a combination for me to see it all.
Jan-21-07  Nibiru: 29...Bb7 30.Qf6+ Kg8 31. Nh6++
Jan-21-07  Silverstrike: <Cuellargacharna> Good morning to you too! The move 29...Bb7 loses to 30.Qf6+ (using the pin on the rook on f8) 30...Kg8 31.Qxf8#

For me, I saw 23.f5 and that black's best response was 23...gxf5, but then the best that I could see was 24.Nxd5 Nxd5 25.Nf4 Nxf4 26.Ra7 Bd7, which isn't that great for white. Now I see that it may bear fruit of some sort after 27.gxf4 followed by maneuvering a rook to the g-file and attacking that way, but of course the game continuation is much better.

Jan-21-07  Nibiru: Or 29...Bb7 30.Qf6+ Kg8 31.Rxf8#, but I like 31.Nh6# most
Jan-21-07  aazqua: Oh snap!
Jan-21-07  laskereshevsky: hello folks

  acirce: Well, being that I solved chess before the universe even existed, these "puzzles" are definitely no match for me either.
Jan-21-07  Themofro: I saw Ra7, but missed f5 first, which was the key to the whole solution, lol. Still got a portion of it on a Sunday, so i'm happy.
Jan-21-07  Fisheremon: As in the game 25.Rd1 (instead of 25.exd6) d5 26.g4 leads to a fierce attack with quicker win.
Jan-21-07  LaSmitedCrab: WOOT, I got it!
Jan-21-07  LoveThatJoker: Fisheremon, I found the drawing line to yesterday's puzzle.


And P.S. I haven't seen answer to today's yet. So I still have got to solve it.

Jan-21-07  RandomVisitor: After 23.f5, Black might offer stiffer resistance with:

1. (1.23): 23...dxe5 24.Ra7 Rb7 25.Rxb7 Bxb7 26.fxg6 Qe7 27.gxh7+ Qxh7 28.Qxe6+ Qf7 29.Qxf7+ Rxf7 30.Ng4

2. (1.31): 23...Rb7 24.exd6 Rf6 25.fxe6 Bxe6 26.Rad1 Nxe3 27.Qxe3 Rd7 28.Qxc5 Bf7 29.Qxb4 Rfxd6 30.Rxd6

Jan-21-07  soberknight: I'm not even going to try to understand what the hell just happened. What a crazy combination!
Jan-21-07  Kings Indian: I got f5 after a while, and got up to Ra7 seeing about all of the variations but i just got lost after Nc7. Good enough for me on a sunday i guess. Brilliant game!
Jan-21-07  Bumcrot: Ivanchuk was only 18 or 19 when he played this game nearly 20 years ago. And he's still a Top 5 player in the world right now. Impressive!
Jan-21-07  laskereshevsky: YAP!
when he ( and i...) was young i thought he possessed th potential 4 to be th

  dzechiel: Missed this one completely. I don't think I spotted one of Ivanchuck's moves.
Jan-21-07  wonderboymyth: One of those games showing Ivanchuk's incredible genius.
