Here is an actual game played with gnuchessr under xboard on a Sun4
server in which gnuchess tries to make a perfectly legitimate move,
but xboard deems it as illegal. The list below is the save file from
xboard. Note that it keeps going long after the actual last move
played. Nothing strange had happened in the game so far. No moves had
been taken back, no xboard commands (other than moves) had been given.
The time control was 5/60 and both sides had time remaining. The
ending position is highly tactical with essentially even material,
following a queen sacrifice about to be regained by queening a pawn.
Black's queen-side castling position has been routed and black's king
is in the center and on the run. I was really looking forward to
playing this one, but I knew it would foul up when I queened the pawn
anyway. I wasn't expecting it to foul up BEFORE I queened the pawn.
Very frustrating.

black's king move appeared briefly, but was put back and the message
"illegal move" showed up. This came with 2:37 left for white, and over
3 minuts left for black. The following moves were never made and
appear to be just random data--they're mostly illegal. After the
illegal move message showed up, black's clock continued to tick away
indefinitely.

We've had similar problems running through ChessTool. There have been so many
illegal moves (eg. R's moving like B's, Q's jumping pieces) that I just call
up gnuchessr by itself and play the game in my head :-).

I'd definitely recommend getting xboard then. I used to use XChess,
but find xboard much better. I couldn't queen pawns in XChess either,
and nearly everytime I took back a move, it would fail. The one thing
I miss is that I had hacked XChess so that I could save and restore
games properly but that doesn't work with xboard (and I haven't found
out why yet.)

Here's one tip that's useful with xboard. It occasionally refuses to
recognize a move (doesn't even say illegal move). When that happens,
if I hit pause twice, I can usually go ahead and make the move.

I've played a lot of games with xboard and it's usually satisfactory.
It's pretty rare that I get into a position of queening a pawn where
the game outcome isn't obvious. Most of the time that it fouls up like
how I posted, gnuchessr's game is essentially lost. This is one of the
few times where it did this in a game that was undecided. It does it
pretty frequently when there's a mate in two or something.

I spent from $3 to $10 today to pay interest on the national debt.  How about you?
