Hi,

Should this command work with xboard as well?

Can I test this somewhere upfront?

Well that was somewhat disappointing.
On the other hand: I found out last night that something terribly goes wrong with the transposition table in my program so I disabled it for the tournament of tonight. Altough I doubt that with a working one it would've won anything anyway.
Ah well, let's see what next month brings.

I watched some of the game of DeepBrutePos, and it seems you have more problems than just having no TT or lack of depth. It sometimes seems to blunder away material with very shallow tactics (like allowing a skewer on its K+Q). This is indicative of a search bug.

You would do well to go to one of these positions, and figure out why exactly it moves how it moves by making a (partial) tree dump and analyzing it.

On the sunny side, you fixed the time-management problem that existed before the tourney really well. Time usage of DeepBrutePos was absolutely normal. In fact the whole tourney went very smooth. There were no glitches at all (disconnects, games having t be started by hand, etc.) It went fully automatic to the very end.

I did some fixing:
- double pawns check was incorrect
- passed pawns check was incorrect
- when I called evaluate (I use the implementation of https://en.wikipedia.org/w/index.php?ti ... ta_pruning), I calculated it from the root-color point of view which should be (I think) the side which is about to move at that search-depth/ply

This version is playing on H.G.Muller's server. So if anyone is willing to give it a try? It still is extremely weak (no idea why) but maybe someone can determine if it became better.

If you want to know how it does it would be much easier for you to just let it play a match against Fairy-Max locally. Then you are not dependent on people visiting the ICS and willing to challenge you...
