Subject: Don't switch to engine-defined variant on game loading
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=22fb70979f674fbf883e007998e8a2399c6745ad;p=xboard.git

Don't switch to engine-defined variant on game loading

When loading a game from PGN the variant tag will have been decoded as
'normal' in case of an engine-defined variant, and we certainly would
not want to switch to that. Better stay in the variant the user had
selected before, and hope for the best.
