Subject: Workaround for FICS bug
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=d799da343a7c2b6aff3d676f63093d4831ba3976;hp=bdaa0499712f23476a46a19ffc6d2ff8b22c3438;p=xboard.git

Workaround for FICS bug

FICS does not properly understand SAN, and thinks bxc3 can be a Bishop move.
This broke 'Upload to examine', because that uploaded in SAN. In case the
SAN starts with Bx or bx, it now uses long algebraic (with = before the
promo char).
