Komodo blunder

[Peter Berger]

BTW I don't know of any version of Crafty that will resign without playing a move. It won't resign until it has played at least 5 moves unless you manually alter the resign count value...

Bob, really - you should be* well* aware of the fact that I *do* know about intended behaviour of Crafty and its parameters. Please have a look at the log below - Crafty will resign before it makes its first move in this position.

This has been pretty interesting. Crafty has lost every game as white and won every game as black, against multiple opponents. .

Here's the actual game that made me describe Crafty's performance in this position as awful. It doesn't confirm your observation.

I'm not aware of fixing any resign bugs at all in 25.0, for me it definitely resigned, but only after playing 5 moves. I disabled resignations and it played just fine. I can post a few of the games when I get home, I think I had xboard save the PGN. I played against scorpio which was happy to play either side. I could only play black against stockfish as it will instantly resign as black. Didn't lose a single game, which is what I would expect. I think I played at 60 moves in 1 minute + 0.5sec increment...

Lots of differences in 25.0 to be sure, but I don't see how any of the changes would affect how it plays here particularly. What is "60/10"??? 60 = moves, but 10=minutes or seconds???

I can set stockfish to play any time control, although I did use one CPU last night to keep it simple.

[Peter Berger]

What is "60/10"??? 60 = moves, but 10=minutes or seconds???

Time control was game in 1 hour aka 60 minutes with 10 seconds increment per move.

I'm giving that a run, although why you would waste that much time for such a whacked-up position is beyond me.

We do have a difference right off the bat, in that ALL I get out of SF6 is d4 as white...

[bob]

Here is the result of the first game. 60 mins + 10 secs. One note. Run on my 4-processor iMac. I didn't notice early on that Stockfish was running on 4 cores. Crafty was explicitly told to use one. I noticed this when I looked at the engine output and Crafty was only a little faster than SF in terms of NPS. No pondering. Xboard captured the usual score and stuff. Game ended with the same result I saw EVERY game end with last night, black winning. I didn't play any games with SF as black as I did not see how to stop it from resigning and didn't want to look thru the code... It apparently uses the same idea as Crafty, resigning after 5 moves with score < something. It's scores are HUGE, however...

Crafty 24.1 is absolutely hopeless against Stockfish 150915 with either colour ( really obvious) , so either the changes in Crafty since or in Stockfish make a very major difference. I haven't looked at your games yet in detail chesswise - but it seems the oddball position produces interesting results, doesn't it?

[Dirt]

I didn't play any games with SF as black as I did not see how to stop it from resigning and didn't want to look thru the code.

If you're using polyglot you set resign = false. You probably are not using polyglot, though.

[bob]

Here are six games, three with early resignations by SF, other three with Crafty winning with the knights.

Don't see this "Crafty plays this horribly" going on. All of these are with SF using 4 cores, Crafty using only one, as a further handicap...

Crafty is winning the current game, again with black, but I am not going to continue this any further... Not very interesting.

[bob]

I didn't play any games with SF as black as I did not see how to stop it from resigning and didn't want to look thru the code.

If you're using polyglot you set resign = false. You probably are not using polyglot, though.

Actually I am, but I use it via xboard. I can probably fake that somehow...

[bob]

This is pretty interesting. I played another game with changed colours and same settings in the meantime:

Crafty 24.1 is absolutely hopeless against Stockfish 150915 with either colour ( really obvious) , so either the changes in Crafty since or in Stockfish make a very major difference. I haven't looked at your games yet in detail chesswise - but it seems the oddball position produces interesting results, doesn't it?

It really should be hopeless playing white. I have yet to see any of the programs I have produce a win with white or a draw with either side. Black has won every last game. But I have only played a couple of hundred...

I probably should try 24.1 just to see if there is a difference...

The new version is about +75 Elo stronger using one core, significantly more with multiple cores. But these were all played with 1 core for Crafty so the SMP stuff is irrelevant. If you are seeing losses with black, this wold seem to be a bit more than a +75 Elo improvement could address...

More after a few 24.1 games...
