|Jul-14-04|| ||RonB52734: This game was discussed in a recent edition of Evans' column in Chess Life magazine, with the focus on 24.Bxg6!.|
Evidently, some folks use the position after 23...Bf7 as a benchmark for chess analysis software -- comparing how long it takes the computer to find 24.Bxg6 as the best move, and (longer still) how long to realize that white has a winning position.
|Jul-14-04|| ||acirce: Seems like a decent test. My Fritz 8 singles out 24.Bxg6 as the clearly best move after 8 seconds; then the evaluation is stuck on +0.50 for about 8 minutes when it changes to +0.76; another minute or so and it shows +2.94. (Yes, many 8's.) |
|Jul-14-04|| ||RonB52734: LOL. I'm asking Santa Claus for Fritz this year. Right now I'm using a copy of a Microsoft chess program that came free on a computer quite a number of years ago. (I think to the extent it has a name, it's "Ziggurat"). I have it running this problem on a Pentium II in the basement (fairly slow, minimal memory). It took it, if I remember correctly, 6 hours to latch onto 24.Bxg6; and, 6 days later, it still has white at about -2.06. (Yes, many 6's!).|
If anybody else is familiar with this program, I'd love to hear from you.
|Jul-15-04|| ||Lawrence: <Fritz 8> wins hands-down here. On our Dell 3 GHz it finds 24.Bxg6 as first candidate in 2 sec. and in 53 sec. already recognizes that White has an eval of +1.34.|
<Hiarcs 9> takes 4 secs. to identify it as first candidate and at 33 sec. gives it an eval of 0.00.
<Rebel 12> finds it in 12 sec., <Shredder 8> in 19 sec. (but after 3 min still thinks Black is winning, eval. -1.36) and <Junior 8> takes 24 sec. and gives an eval of +0.26 at a minute and a half.
|Jul-15-04|| ||zb2cr: Not surprising that some programs take so long to find the win for White--the position is so sharp. Looking at the actual game combination, the thing that makes it work is White's 29th. That's 11 ply deep, a challenge for any program in a middle game like this. |
|Jul-15-04|| ||rndapology: Lol Ron...I am very familiar with that program. I used to play it when I was in 4th grade. I beleive it is a part of the Windows Entertainment Pack. IMO you should dump that useless prog and download say GnuChess(free) for the time being until and if you acquire Fritz. Ziggurat or MS chess is absolutely horrible. |
|Jul-18-04|| ||RonB52734: Lol got it. Thanks for the gnu information! |
|Jul-22-04|| ||RonB52734: <rndapology> I downloaded GnuChess version 4.something the other day. I understand there's a version 5.something out now, but I haven't had time to work through the very confusing instructions for downloading that from the ftp site.|
In order to allow me to compare Gnu's evaluations to Ziggurat/MS chess, I'm going to play them against each other this weekend (if my wife lets me).
Ziggurat's evaluations are a number between 40.000 and (minus) 40.000, always viewed from white's perspective, where +1.000 is more or less equivalent to a pawn, and 40.000 means it has found a forced mate. From what little I've seen so far, Gnu's evaluations are from 9999 to (minus)9999, viewed from whichever perspective Gnu is playing, where 9999 means it has found a forced mate.
|Jul-22-04|| ||Calchexas: Uh...forgive my stupidity, but what's the winning line after 24...Bxe6? |
|Jul-22-04|| ||Chessical: <Calchexas> If Pilnick played <24...Bxe6?> then:|
25.Bxh7+ Kh8 (25...Kxh7? 26.Rh1+ with mate to follow) 26.Rh1 and wins
|Sep-10-04|| ||RonB52734: Incidentally, for those who have been dying of curiosity: revive yourselves. GnuChess 4.x beat Ziggurat (MS chess) 2 games to 0 taking turns with the white pieces. At every step, Gnu managed to look ahead 1-ply more than Ziggurat given the same time control. This led slowly but inevitably to the 2 wins. I have the games written down here somewhere. |
|Feb-09-06|| ||who: <Calchexas> or if 24...Bxe6 25.Bxh7+ Kf7 26.Bg6+ Kg7/8 27.Be8+ Kh6/7/8 28.Rh1+ |
|Mar-01-08|| ||Mate Hunter: <GM Larry Evans presented this game in Chess Life February 1999 in response to a reader's request for his best game. GM Evans explained that this game brought him to the attention of the chess establishment at age 14. GM Evans won more accurate games against more worthy opponents over the board in his career (Evans-Opsahl Dubrovnik Olympiad 1950), but few as exciting as this. I am sure you will agree that the sacrificial style of play is entertaining.> (http://www.logicalchess.com/resourc...)|
