Hi, I have the following question about GNUCHESS 3.0:

Near the end of MakeMove (gnuchess.c):

>    if (node->flags & epmask)
>	EnPassant(xside, f, t, 1);
>    else
>
>#if ttblsz
>	if (hashflag)
>	    UpdateHashbd(side, board[t], f, t);
>#endif
>
>    Mvboard[f]++;

Do you think it should be:

>    if (node->flags & epmask)
>       EnPassant(xside, f, t, 1);
>    else
>
>#if ttblsz
>       if (hashflag)
>           UpdateHashbd(side, board[t], f, t);
>#else
>	; /* for the 'else' above if ttblsz == 0 */
>#endif
>
>    Mvboard[f]++;

This change ensures that Mvboard[f] gets
updated irrespective of the value of ttblsz.

The same change should be applied to a similar
piece of code near the end of UnMakeMove.
