1st CCC World Computer Crazyhouse Championships

[Ferdy]

In around 3 days from now I will be conducting a 5-round swiss championships qualifying tournament for the following zh engines. The top 3 will advance for a quad-round robin championships.

Code: Select all

Imortal v2.5
Sunsetter v7g
TJChess v1.1
Sjeng v11.2
Pulsar v2009
KKFChess v2.6.6
Nebiyu v1.45
Sjaak II v1.3.1a

The TC is 90 minutes + 30 seconds increment, using a variety of 2 pre-defined start positions. Each match is best of 4 games from 2 1st round start positions. In the 2nd round new 2 start positions will be used and so on.
Other conditions: Hash 512MB, Threads 2 max, Ponder off, Ownbook off, Learning off, egtb off. I will be using winboard 4.8.0b GUI to run the tourney. Hardware: i7-2600K, 4-core, 12 GB, 3.2 Ghz.

If you have an engine that can play this variant or perhaps an update of the version, and wanted to update your engine, contact me.

I have a question:
Why does the promoted piece appear as a Black one and why as a star?
(Is this because of my choosen piece set? I am not familiar with crazyhouse)

[Ferdy]

Perhaps it is because of the piece set. I am not really sure.

[Isaac]

Very nice... I expect Sunsetter, TJchess and Imortal to qualify.
I love crazyhouse. I wish there was an engine using multi threading, that would be a first.

For mt i think nebiyu can but seems to me daniel did not release an alien version compiled with mt enabed or perhaps i just missed it.

[Ferdy]

Could you suggest an interesting position for wc final, perhaps 2 or 4 positions.

I am trying to create a crazyhouse chess variant association.

I have a question:

(Is this because of my choosen piece set? I am not familiar with crazyhouse)

WinBoard normally uses different internal piece types and images for pieces that are promoted Pawns rather than primordial pieces. This to make it visible whether they will turn into Pawns on capture, or stay themselves.

You are probably using font-based piece rendering, which requires definition of a -fontPieceToCharTable to map the piece types to the piece-font characters that show up as the required glyphs. For normal Chess this only has to define 6 piece types for each color, and thus would look something like "PNBRQKpnbrqk" if the piece font would have the obvious character mapping (which, alas, many piece fonts do not).

For crazyhouse this would need "PNBRQ......PNBRQKpnbrq......pnbrqk" to also define images for the piece types WinBoard uses for promoted Paws (which come 11 places later in WinBoard's piece ordering than the corresponding primordial piece). If you use the same letters as for the first 5 the promoted Pawns will be indistinguishable from the primordial ones. An alternative is to let them keep the appearance of a Pawn (which is common practice in OTB bughouse play), by defining "PBRQ......PPPPPKpnbrq.....pppppk". Neither is ideal, but if the font you are using has no other glyphs than the 6 orthodox Chess pieces there is little else you can do.

WinBoard sets all pieces not defined in pieceToChar strings to '.', and probably the fpiece font you are using displays '.' as a black star.
