test position

Post by jdart » Sat Sep 06, 2014 3:53 am

This was from a correspondence game but White missed the best move:

[D] r2q3r/pbpp1kbP/1p2pn2/6B1/1nPP3Q/8/PP1NNP1P/1BKR4 w - - 0 15

bm Rg1!

Arasan 17.3 gets this in about 4 1/2 minutes on a quad.

That looks pretty deadly...I'm surprised White missed it. Who were the players?

These are not strong players. I cam across this move analyzing the opening and then saw ithe position had been reached in a game. I don't rule out it might have appeared before, but here is the game:

This time iCE is lucky and suspects it rather fast with a +0.52 score jump. The score goes then up each additional iteration, at depth 19 it is already more than 3 pawns.

I am going to start Komodo 8 again and let it run while I mow my yard.

But Komodo 8 with a quick 10 minute deep position analysis (22 seconds per half-move) with three branches found the move quickly. Unfortunately in engine vs engine matches deep position analysis or even multivariation mode is not possible so K8 would probably miss this move under standard tournament time control.
