How long until your engine sees Bh3? (It takes a while for h5 to fade).
I am wondering if any engine sees it before ply 19.
Rybka took about 1/2 hour on my hardware, and IvanHoe about a minute.

Hi Dann,

Following is Rybka results after letting it crunch for 72 hours. What version of Rybka did you use Dann?
I used Rybka 3.0 with 4 CPUs at 3.0 GHz, 2 GB hash tables.
My results are so much differnet then yours?
You did not analyze the position that is posted here. Notice in your key move the rook starts at g5 and moves to h5. Now look at the picture above. There is no rook on g5 for either side.

Avoid move:
Best move (Rybka v2.2n2.mp.w32): Rg5-h5

Hi Dann,

You are right my mistake for posting it here. It was in reference to this post by John Merlino, look above.

Post subject: It's time for this position again Posted: Mon Feb 01, 2010 1:00 am

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:
