Re: PyChess 0.99.1

This is indeed what I expect to work. The problem with Python is that every version seems to install itself in a different directory, so that WinBoard cannot automatically invoke it based on the extension of the 'engine executable', as it does for Java (.jar) files.

Re: UTIL: PGN Translator already written?

Looks like German (but it could be that Swedish is the same). WinBoard has an option -pieceNickNames that can be used to define a set of alternative IDs during SAN or FEN parsing. E.g. specifying -pieceNickNames ".SLTD..sltd." would make it recognize S as Knight, L as Bishop, etc. It would still rec...

Re: Command line tool to output round-robin pairings?

Not that I know. But the algorithm is extremely simple. After you make arbitrary first-round pairings, for each next round you shift the left column on place down, and the right column, except the last player, one place up. The players that shift out of the range move to the position left open in th...

Re: Winboard nodes display

That is very ancient history, and not much from that time has survived.

Re: On-line engine blitz tourney October

It was an amusing game. NEG ended up with big material advantage but failed to mate. Yeah, I had a look at it. Amazing that NEG could give that away. Normally the preference for checking with a new piece is enough to force mate with a large material advantage. The most obvious weakness of NEG is th...

Re: On-line engine blitz tourney October

@Roller: Oh, I was still there, but only saw the NEG-Roller game and your message after you left. NEG has no search; it counts attackers and defenders of each square, and uses a simple heuristic to give a value of the capture to that square (assuming you gain the full value of the victim if it is un...

Re: On-line engine blitz tourney October

But limiting it to LxH and equal captures could be a good idea. Can't do that as that it's semantic knowledge :) I guess you can disguise it as a game move, though: suppose you alter the game such that instead of just starting to moves, the players decide on a strategy first, and only then start mo...

Re: On-line engine blitz tourney October

I am as inexperienced as you in this, but what you propose seems dangerous. The largest part of all rollouts will be unique, the nodes never being visited again. Preferring captures will almost always lead to the Queen capturing a protected piece (mostly Pawns!) before the end of the game, with a hi...

Re: 12th ACCA World Computer Rapid Chess Championships

Note that for those who want to test their setup for on-line tournaments, there will be an opportunity in the blitz tourney on the 13th.
