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
definatly an ingenious mind.....
unfortunatly not always.....
Jan-21-07  Slink: this was easy for a sunday. got it in about 0.00000001 seconds. 8/7 this week
Jan-21-07  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
Jan-21-07  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.
Jan-21-07  THE pawn: Holy crap...I completely missed the whole puzzle. I thought a lot about f5 but then Ra7 was just fantasy for me. Fantastic, really.

  kevin86: I missed this one-no great sin. A fantastic finish!! Black cannot either decline or accept the sacrifice and loses very quickly.
Jan-21-07  Fisheremon: <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>

As far for the 1st line: 27.Ng4 (instead of gxh7+) Bc8 28.Nxe5 Qg7 29.gxh7+ Qxh7 30.Qd2 Qg7 31.Ng4 with attack and quite difficult to find a good move for Black

As for the second line: 24.g4 (instead of exd6) gxf5 25.Nf4 Nxf4 26.Bxb7 dxe5 27.Red1 Qe7 28.Bxc8 Nxc8 29.Kh2 Nd6 30.gxf5 with a nice attack on 6th horizontal.

Jan-21-07  Amarande: As for Black's final plight, if 29 ... Rxd8, then 30 Qf6+ and 31 Nh6#. Black's only hope is to connect his Rooks by giving up the Queen with 29 ... Qxg2+ 30 Kxg2 Bb7+ 31 Rxb7 Rbxd8, but even then after 32 Rxc7 he is naturally gone ...

I didn't see it, myself ... I saw a kingside attack brewing and my impression was that I should begin bringing my pieces up for the attack with some such move as 23 Ng4.

Indeed White still has much the better of it after 23 Ng4, Junior 9 after 16 ply giving 23...Rf5 24.Qh4 Rf8 25.exd6 Qxd6 26.Ra7 Rb7 27.Ra5 Rg7 28.Nf2 Ne3 29.Ne4 Nxg2 30.Kxg2 Qd5 31.Rxc5 with an evaluation of +1.14, but it's nowhere near as good as the quick win that follows f5!

Jan-22-07  alphee: Did not get it. I saw 23.f5 gxf5 and also Ra7 possible back answers but could not put them together. Sunday's puzzles are a definite challenge
Jan-22-07  ALEXIN: Both:very strong and subtel !
Feb-28-09  WhiteRook48: does Nenashev mean computer? :D
