Re: Komodo 1.2 crash in KPK ending

Don, this test was run with cutechess-cli, repeating TC of 40/5 (seconds). The three times I've looked at the PGN after a crash I found a drawn KPK endgame in which Komodo had the KP side. The problem could obviously be more general - KPK may be the only configuration where Komodo encounters "whatev...

Komodo 1.2 crash in KPK ending

Not sure whether this is a known problem, but Komodo 1.2 sometimes crashes in drawn KPK endings. See for example the game below, in my experience this happens approx. once every 1000 games. Hope this helps, Robert [White "Komodo_1.2"] [Black "Houdini_CDFO"] [Result "0-1"] [FEN "rnbqk1nr/pp1pppbp/6p1...

Re: A chess wish

Your wish can be granted :).
I can compile a 12-thread x64 Houdini development version, optionally with Large Page support, if you like.

Re: IPON results after 841 games

1.8 is probably only about +20 ELO, but nevertheless it was a good idea to publish a new version. Bugs were fixed, redundant code was removed (for example queen contact mate detection in eval is gone!), many things were reorganized, the executables are noticable faster now. From what I've seen so f...

Re: Testing DamirsRK60 and 61

Tom, A couple of observations. 1) A core i7-975 only has 4 cores with hyper-threading. Running engines with 8 threads will in the best case produce a speed-up of about 20% compared to 4 threads, most of which will not translate into Elo strength (8 threads have more overhead than 4 threads). Your re...

Re: Rybka 4 vs Houdini 1.02 - Long TC Match - LIVE BROADCAST

The 6th game (currently running) is really interesting.
At move 48 Rybka has played the Black king to g5 in a vey complex middle game position.
Will Houdini crack Rybka's defense?

Re: pawn racing

It is not correct solution. Houdini has a problem with 6th white move (pawn endgames). Of course, the line shown is not Houdini's final analysis - as you can see from the ++ in the score we're still in a fail high condition, or in other words, the PV shown is meaningless. To get the full main line ...

Re: pawn racing

Houdini has another problem and probably can't solve it. Maybe Stockfish is realy the best in endgames. :D Using 4 cores Houdini 1.02 finds Kd6 at depth 31 in about 2 minutes: 30/67 0:32 +3.66 1.Be4 Nxc2 2.Bxf3 Nb4 3.Be2 Kd4 4.Kc7 Ke5 5.Kb7 Kd6 6.f4 Nd5 7.f5 Nf6 8.Bf1 Ng8 9.Bd3 Nf6 10.Bc4 Ne4 11.Be...

Re: New engine test for the IPON list is running

Btw: Houdini still tends to crash from time to time in the Classic. It is not the worst engine but for from good (~1% of the games / most enignes have a0% rate!) Wow, that's way too much! I haven't encountered a single crash with version 1.02 so far - and, as you can imagine, I'm running games non-...
