Hi,


Yes, IF you tell Chest the parameters :)

But I agree this is how problemists work to test their own problems.

Re: PopeyeUCI 1.7 is still on the search after 1 day... (nt)

I'm going to have Zappa Mexico II look at thsi for at least 12 hours. I had Zappa and a few other engines search for 10 -15 minutes each, with no results other than the dead draw as earlier mentioned. I see the issue after watching the analysis window scroll by: 4 - Bd6 is initially given such a low score, that it is put at or near the end of the search order. It appears that this causes engines to spend less time looking at the move in later plies. I was just watching Deep Sjeng look at the position. 4 - Bd6 scrolled by so fast that I didn't notice it being considered.

This has been interesting for me. After 21 hours, on my I7-920 2.67 GHZ, Zappa Mexico II still sees a dead draw!
