Re: Nullmove bugs

if (depth >= 4 && nodetype != NodeTypePV && !incheck && PopCount(b->sidemask[b->side] > 2)) { [­/code] How did you come up with depth >=4? Depth >= 2 works best for me. Make sure you call qsearch when depth <= 0 and not depth == 0 if you make this change. Nullmove reduces by R + 1. My R is 3, so 3 ...

Killing your opponent with a jet fighter. That could save the day if you're in trouble. I bet it's not mentioned in the rules either, at least not specifically.

It was actually shown in the first post by Jon himself that this is (most likely) the best version ever. Maybe he referred to that and not his own tests.

Re: Low price cpu recomendation.

Hello Friends! somebody has benchmarks of this Cpus?! Athlon 5150 AM1 . Is a Quad core 1.6Ghz. My doubt is what would be best Athlon 5150 / Apu A4 6300 vs Celeron/Pentium g1850/3250.

Re: Latest Stockfish vs Komodo 10 - 200 Games TC 15 min / 15

Are you sure about that? On the CCRL homepage it says:

Re: Collecting the pv in Search

Another thing. The lines after the move loop: NodeType node = Alpha; TT.save(depth, move.Score, move, node, Get_Current_Hash_Key()); will erroneously overwrite any best move and exact score you may have found earlier within the loop. Edit: Unless you somehow avoid that inside TT.Store() of c...
