SjaakII 1.4.0

Post by Evert »

SjaakII version 1.4.0 is available from http://www.eglebbk.dds.nl/program/chess-download.html (source, OS X and Linux binaries; Windows binaries will follow).

This version includes a major change in Sittuyin rules. They now follow the rules as described in http://www.docfoc.com/how-to-play-myanm ... eng-book-1, which are apparently the official current rules. The rules are now this:
  • Pieces other than Rook may be dropped anywhere on your own side of the board. Rooks may still only be placed on the back rank (used to be: other pieces may not be dropped on the back rank).
  • Promotion can only happen if the pawn starts its move in the promotion zone, not when entering the promotion zone.
  • Promotion is either in-place (replacing the Pawn by a Ferz), or by moving as a Ferz (alternatively, promotion is in-place, and then you may decide to move the Ferz or not).
  • Promotion moves must be quiet: you're not allowed to capture a piece, and the Ferz is not allowed to attack an enemy piece either. You also cannot deliver check (direct or discovered).
  • The last pawn can promote anywhere (it doesn't have to be in the promotion zone).
Many thanks to Tote Kyi for pointing out these updated rules.

There are also two new variants: Caïssa Britannia and Nightrider Chess.

There is now rudimentary support for customising the evaluation. The engine options dialog has an option "Evaluation parameter file", or you can add a command-line option "-eval <file>". The evaluation file should look something like this:

Code: Select all

Variant: Chess

Value N  325  325
Value B  325  325
Value R  500  500
Value Q  975  975
Value K  8000  8000
Value P   80  100

}
To see the current/default settings, start SjaakII from the command line and type "show eval parameters".

New options for custom variants:
  • Move: ride (x,y) and Capture: ride (x,y), for riders.
  • Rule: en-passant check. Kings that move as sliders cannot pass a square where they would have been in check.
  • Rule: quiet promotion. Promotions must be "quiet" moves.
  • Rule: promote by move. A piece in the promotion zone promotes by moving as the promoted piece.
Other changes include minor bug fixes and a tempo bonus in drop-games (which improves strength in Shogi and Crazyhouse).

Re: SjaakII 1.4.0

Post by Evert »

Also included in this release (with the source anyway, no binaries) is an updated version of the match-playing program Sjef. This is a command-line tool similar to cutechess-cli for engine matches. It uses an external program (by default SjaakII) as a referee.

I'll document this more fully when I get the Windows port for that up and running.

This version of Sjef actually doesn't depend on SjaakII in any way, so it probably makes sense to put it in its own version control system and release cycle.

Unfortunately I can't reproduce it. I tried pasting the position in question as well as stepping through the game in analysis mode...

Re: SjaakII 1.4.0

Post by hgm »

I must admit that Sjaak II (1.3.1) in my tests was also not entirely reliable, and suffered from occasional crashing. This is one of the reasons I stopped using it as a test opponent. (The other reason is that CrazyWa surpassed it in strength. Although I had the feeling that most of the weakness of Sjaak II in Crazyhouse is due to bad piece values, in particular a gross over-valuation of the Queen. Largest score differences would occur when Crazywa sacked a Queen, e.g. both engines being at +2, and then Sjaak almost always would lose from such a position.)

Having Sjaak crash would hang the match, as it produced the dreaded Windows popup informing the user that the application is no longer functioning properly, but not killing the process before the user OK's that dialog. Although Sjaak would then flag during that game, in the next game WinBoard would wait for it to respond to the protover command indefinitely, causing the match to hang. The normal cure for this (which I also used for CrazyWa, which was also crash prone at that time) is to install the engine with the /xreuse option. The you just see all the error popups of the zombie processes the next morning, and can close them without WinBoard even noticing. But when I tried that with Sjaak II, something very strange happened: it crashed WinBoard, which stopped responding to mouse events and would not start new games. Not sure how Sjaak managed to do that.

May be this helps:
I pasted the game in WB and started analyse mode. Then I went up to move 30 IIRC and went slowly back in the game for a few moves.
Suddenly it started to forget about the already since long found mate and even worse the PV was full of moves ignoring checks and other things.

Edit: I checked some of the FENs produced by SjaakII on the way
back in the game and they contain 2 Kings! (sometimes both in check!).

There is definitely sth fishy going on.
Note that I just had downloaded the WIN version of SjaakII 1.40 and let it all as it came (= no change to variants.txt)

Re: SjaakII 1.4.0

(The other reason is that CrazyWa surpassed it in strength. Although I had the feeling that most of the weakness of Sjaak II in Crazyhouse is due to bad piece values, in particular a gross over-valuation of the Queen. Largest score differences would occur when Crazywa sacked a Queen, e.g. both engines being at +2, and then Sjaak almost always would lose from such a position.)
I think the only thought I ever put in piece values for Crazyhouse was to make the value of the promoted pieces higher than their normal counterparts. I clearly never put much thought in them beyond that. In Shogi I scaled the piece values by a factor of 2 or so to make material less dominant (and also to avoid double-counting), but it seems I didn't even do that. Doing just that seems to boost the self-play results by ~100 Elo.

Looking around, I found https://nl.lichess.org/blog/VrQDNSoAACs ... n-overview, which lists P=2, B=3, N=3.5, R=4, Q=6. Is that accurate?

What worries me though is that it apparently misbehaves. The reason that worries me is that I never see it do that in any of my own tests, though come to think of it, I think I only run two consecutive games (one pairing) per instance (a script controls how many concurrent instances of XBoard to run and with what parameters). If you have more details about this, that would be very useful!
