Crazyhouse Computer Championships 2016

Is SF sse a zh variant too?

SSE is a special edition of SF : http://talkchess.com/forum/viewtopic.ph ... 788#692788

I guess SF sse in that link does no play zh is that right?

BTW could you inform the authors of Sf zh that the zh championships will now be held this coming 2016-12-02. Perhaps they have some build to participate. Thanks.

Done !

There's a consensus to use this version : https://github.com/niklasf/Stockfish/releases
No last minute changes to avoid troubles.

I will take that.
Engine update is allowed, so bug fixes and further improvement can still be entered.

Interesting, so this new SFzh seems to lose on time when it finds a checkmate? If so, that's a bug worth investigating.

[Vinvin]

Is SF sse a zh variant too?

SSE is a special edition of SF : http://talkchess.com/forum/viewtopic.ph ... 788#692788

I guess SF sse in that link does no play zh is that right?

BTW could you inform the authors of Sf zh that the zh championships will now be held this coming 2016-12-02. Perhaps they have some build to participate. Thanks.

Looks unstable, there are 3 loses on time at TC 3'+2".

The TC management used is the same as the official Stockfish (known to have a bad behavior).
Please set "move overhead=100" to make it plays a bit faster.

But the last change directly concerning time management is around 2 months old?
I think this means it is more likely another bug was introduced in the ZH version.

(at least if the number of time losses increased significantly since 151116
or 021116)

I don't know. The time management is a touchy part of SF.

Change : with 60min+10s time control, we can set "move overhead=1000".

I now uploaded CrazyWa 0.1.2. It differs from version 0.1.1 only in that I retuned one parameter (I tripled a certain contribution to the King Safety). This performed some 3% better against my usual gauntlet of Imortal 1.0, Sunsetter 7g, TJchess 1.1 and CrazyWa 0.0.8. And against CrazyWa 0.1.1 it is nowleading by 3% after 400 games, which in itself is barely significant, but at least makes it quite unlikely that it is weaker. So this is the version I want to enter in the championship.

I could not reproduce the crash you reported on 0.1.1. If nothing was written in dump.txt, it was not due to an assert. I have suffered one crash in many thousands of games (weeks of continuously running 4 games in parallel) here too, which was due to an assert, but I could not reproduce that either. It is likely due to a hash-key collision creating some very rare situation due to an invalid hash move that is not detected, but cannot be properly handled.

After 1600 games 0.1.2 beat 0.1.1 by 55.3%, so I have good hopes it is indeed an improvement.
