Stockfish 1.8 demolishes WAC.230

Post by Dann Corbit »

In 16 seconds it simultaneously finds both the solution, along with Alex Szabo's brilliant refutation, and then finds a refutation to the refutation.

Amazing. No other engine comes close. Crafty 20 with Jeremiah Pennery's wall detection code can find the solution but it takes much longer to see Re2 after c3 and cannot find the final continuation. Other engines like Rybka, Critter, Ivanhoe... flail aimlessly for hours (no clue what to do after an 8 hour search).

Dan here is your line from your post. Look at move 15.Kg3??
Also look at final position after playing out, does not look convincing even after correcting move 15.

There are only three choices, and none of them look very good.

Stockfish gives different answers (Kg3/Kh5) depending on which one it finds first. When it does find Kh5 first, it does seem to be difficult to make headway. I guess that the question is still open. Here is Stockfish analysis of the position in question after it finds Kh5, followed by one where Kg3 was preferred):
