Re: Piece value
Game results are not very sensitive to the piece values assumed by the playing agents, and as a result it is very hard to tune them from game results. Especially if a piece is much stronger than all others, the assumed values don't matter very much, as long as it is high enough to discourage 1-on-1 ...

Re: Counter-Picking
I think he means with 'the same piece' that black and white get the same piece, no matter who chooses it. Not that black chooses the same piece as white when his turn to choose comes up, so that each player has a pair of those. (Which I thought was not allowed by the rules anyway.) And I agree with ...

Re: NextGen Pawns, how to improve the Classic Chess Pawn
Concerning the issue of novel pawn types, the following post of Matts Winther might interest you: https://www.chessvariants.com/index/listcomments.php?id=40765 In short, he proposes (in simulation of medieval battle) connected head-to-head pawns to push the opposing Pawn one rank backwards. It seems...

Re: Win-Draw rates when playing with various modified Pawns: The Lieutenant Pawns, Moscovia Chess
My experience is that it doesn't matter very much which engine you use, as long as you play it against itself. Because in that case any preference associated with style (e.g. like aggressively going for a King attack), and even plain misconceptions (wrong piece value that inverts the desirability of...

Re: Some results from Musketeer Chess End-Game Tables
FairyGen is an EGT generator for pawnless 3, 4 or 5-men EGT with fairy pieces. It is available from my website at http://hgm.nubati.net/fairygen.zip . The package contains separate executables for 3-, 4- or 5-men endings, plus a piecedef.ini file that defines how the various pieces move. Usage is fo...

Some results from Musketeer Chess End-Game Tables
I investigated some pawnless end-games with Musketeer pieces, to determine their drawishness. (Which often plagues pawn-less end-games.) To this end I had FairyGen generate the required End-Game Tables, and interpreted their statistics. For a chess engine it is important to have such knowledge; othe...

Re: Win-Draw rates when playing with various modified Pawns: The Lieutenant Pawns, Moscovia Chess
How do you mean, remained high? I usually see only about 32% drawing percentage in orthodox chess. I am not sure that tinkering with the Pawns will achieve much in this respect anyway. The extra moves might help a bit for winning KP-K, but only a tiny fraction of chess games ends in KP-K. It doesn't...

Musketeer Chess engine (free download)
I converted my engine KingSlayer (a simple demo) to play Musketeer Chess, and made some slight adaptations to WinBoard to work well as an interface for this. I especially focused on human-engine games, and how the engine could use WinBoard to conduct the game 'prelude' in which the players negociate...

Re: Geneva Chess available on Musketeerchess.net
XBetza would allow you to create only e.p./o.c. rights in the non-passed square by splitting the oblique move in one that hops (and doesn't create rights) and one that 'moves' (and does create rights): ifmnarmnalWifmnarpalWifmnalmnarWifmnalparW The 'm' would all be redundant here, as move-only is th...

Re: Geneva Chess available on Musketeerchess.net
OK, that explains it. So an oblique Pawn move like b2-c4 can generate both an e.p. square and an o.c. square, depending on presence of enemy Pawns (on a4 for e.p. and on b4 for o.c.). The o.c.-square is different from an e.p. square in that it matters which capture move (left or right) of the Pawn r...
