Chessmaster v Christiansen test position (2002)

Post by JVMerlino »

I've dug this one up a few times since it was played almost fourteen years ago, and I don't think any engine definitively answered the question one way or another. It's been a few years since I last posted it, so I guess it's about time again....

This is a position from round 3 of Chessmaster vs. GM Larry Christiansen:

[D]8/p1p5/Pp1p2nk/1P1Bq1r1/2P1Pprp/1Q6/5RPP/3R3K b - - 0 53

At this point, Larry played 53...Rg3?! Afterwards, he claimed it was winning. But unfortunately he blundered later on in the game and lost.

But with today's powerful engines and hardware (neither of which I have), I would very much appreciate it if any of you could run this position and see if any engine can find a win for black AFTER playing Rg3. Bonus if an engine actually DOES play Rg3!

Here's the game, for your amusement:

Perhaps Larry saw something that the engines didn't, it would have been cool if Larry had demonstrated the win after 53...Rg3 for further scrutiny.

I first analyzed the position after the key move was made. For a while, it looked like white was in trouble (up to depth 28) but then it faded to a draw.

Now I am analyzing the original position before the key move was made.

Analysis of the position after the key move has been made:

Depth reached was 52/83.

This SF thinks that the best that Black has is a draw with ...Qf6 as the first move after 11,720 seconds of "thought" on a single core i7 2.8 GHz CPU.

It seems most everyone that ran this through SF is coming to the same conclusion -- a draw is what seems most likely. It would be nice to know what Larry C thought he saw in this position.

Re: Chessmaster v Christiansen test position (2002)

Post by Dann Corbit »

Here is the position analyzed before the key move was played.
It appears that (according to SF) the best move is Qf6 which draws. It appears that Rg3 and Rh5 also draw.

Since most everyone chose SF, maybe we should re-examine with a different engine.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Chessmaster v Christiansen test position (2002)

This is a position from round 3 of Chessmaster vs. GM Larry Christiansen:

[D]8/p1p5/Pp1p2nk/1P1Bq1r1/2P1Pprp/1Q6/5RPP/3R3K b - - 0 53

At this point, Larry played 53...Rg3?! Afterwards, he claimed it was winning. But unfortunately he blundered later on in the game and lost.

But with today's powerful engines and hardware (neither of which I have), I would very much appreciate it if any of you could run this position and see if any engine can find a win for black AFTER playing Rg3. Bonus if an engine actually DOES play Rg3!

Here's the game, for your amusement:

WaDuuttie indeed wants to play Rg3 but with a score dropping towards 0:

I noticed that after 53...Rg3 54.hxg3 hxg3 WaDuuttie changed from 55.Ra2 to 55.Rf3. After 55.Ra2 (as played by CM9000) it seems 55...Rh5+ is indeed winning.

Hello Maarten,

It looks like you are right that 55.Ra2? wasn't the best move as far as Stockfish is concerned in the position you posted:
