bm Bxf5
Thanks Jon, seems like a good test! So far only looking at #1 Naum 4 - Cyclone pos. The latest experiments I made are probably a failure especially in these complicated positions, the eval is going up and down without getting any real depth. But I would have expected Ancalagon to at least look at Bxf5+, but it is only move number 21 in the move-list. So either it is wrong or Ancalagon is missing the point of the move completely even in multi-PV...

By the way, spreaking about Naum, Naum fans may like to hear there are rumours that the Naum project is not completely finished, but that is just from one poster on the Rybka forum who says he e-mailed Alexander Naumov.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

bright was the fastest i've tested on the first position. Finds it instantly, went to Rf3 then goes back to it later on.

After 8 minutes, it still sees Kf1 as the best move.

I think Crafty should eventually be able to find Rybka Dynamic's move Peter, given more time, or more cores. I just tried the latest version of Ancalagon on the position and it fails high twice after 11 minutes 9 secs:

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
