Thanks Sergio for the finding and Dann for the compile :)

After a quick test under Winboard, it appears that Gray Matter has the bad habit of rejecting legal moves from the opponent, which is an ugly way to win games :shock:

Hello Olivier,
In my PC, Dann Corbit, Grey's executable compile, show an error message and exit from Winboard. I have Windows 2000 OS. Maybe the winboard command line needs some extra parameter.
Please you comment.

Hello all. I took a quick look at the code, and this engine doesn't seem to read command line parameters at all.

I've found that this engine crashes with a time control of game in X number of minutes (like a level 0 3 0 type command), but seems to run ok with a time control of x moves in y number of minutes, at least in Arena 1.1. It's probably a divide by zero type bug; I've seen a number of other engines, especially old ones, crash when issued a level command with the first parameter being zero.

As far as not accepting legal moves, it seems to interpret Winboard 2 style usermove commands ok, but it doesn't seem to understand Winboard 1 style move commands (usermove e2e4 is ok, a plain jane e2e4 is verboten).
