I've dug this one up a few times since it was played a little over seven years ago, and I don't think any engine definitively answered the question one way or another.
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 now that we have all these new incredibly strong engines (no comment about their origins necessary), I would very much appreciate it if any of you with top-end hardware 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!

Re: It's time for this position again
IvanHoe v68 finds Rg3, with an increasing score for black. It would take a long time to find a win, if it exists. Perhaps on faster hardware ...

Re: It's time for this position again
Very interesting position.
I haven't a high-end machine, but in my crappy laptop Stockfish 1.6 finds Rg3 in 8 minutes and a half. It isn't a winning move but it looks like it's the only option if black wants to avoid a draw.

I haven't a high-end machine, but in my crappy laptop Stockfish 1.6 finds Rg3 in 8 minutes and a half. It isn't a winning move but it looks like it's the only option if black wants to avoid a draw.

Re: It's time for this position again
Rg3 doesn't appear to give any advantage, but he could have got an advantage of a pawn and a half (by the looks of things) after 56. Kg1 if he had played 56. .... Rh4

Re: It's time for this position again
IIRC, I analyzed with engines at this time and I found only a draw while searching a lot of lines ...

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.

Re: It's time for this position again
Me too. I analysed many lines with the help of some engines and could not find a win for black. I looked for more than 4 hours, maybe there is some winning line, but it is difficult to find, at least for me.

Re: It's time for this position again
Hi John,
I am analyzing this position with Rybka on my quad which will be a 72 hr analysis. Hopefully something will show. I will keep you posted.
