Re: Stockfish 1 - Stockfish 7 in Arasan testsuite

As we all know testsuites are almost useless to detect any engine progress. Are they? Arasan suite v19 gives surprisingly steady increase even with SMP randomness. Solved positions with 30 s and 4 cores: SF 1 101 SF 2 103 SF 3 119 SF 4 124 SF 5 138 SF 6 145 SF 7 156 And SF 24.9. - surprise, surpris...

Re: SPCC: Testrun of Stockfish 160830 finished

Most likely error bars (in the prior two testruns).

I believe my LMR-Capture patch helped considerably at STC.

Re: Sorting Captures

Actually no, it shouldn't. QxQ is at best an equal trade, so it gets a score of 0. PxR is a winning trade, so it gets searched first. Why would you search equal captures before winning captures? No at best QxQ is winning a queen. You need to get rid of the assumption that each piece is protected an...

Re: Sorting Captures

@Matthew You are doing something wrong then... What is confusing is that you don't subtract the two!! MVV - LVA The hypen(-) doesn't mean subtraction! Let say you have two captures; A. Queen is captured by Queen B. Rook is captured by Pawn Based on MVV - LVA: "A" should be your first selection. An e...

Re: Komodo shows TB hits in starting position

My guess is that K probes in Q-search.

It may have an internal EGTB, with the most common piece constellation, in order to keep memory foot-print low.

Re: Komodo 9.4

Hey Team K. Congrats on the new release. Regarding "King Safety": I believe that raising king's safety helps hides one of Komodo's main weakness, which is a position with many checks. This game is an example...it took many game plies for K to understand what was going on. Game 43 of the previous Gra...

Re: Games 27 and 28

IMO, Graham's Tournament is much more interesting than TCEC.

Real time Engine outputs. (BIG plus)
Sharp openings.
Lively and exciting games
Good Draw Rule.
Games are "Watchable" (i.e. not too long and not too short)
Stable
