Subject: Make Hoplite moves irreversible in Spartan Chess
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=d2a7786025d6bdb8cbd7e3b38a068185d2f93222;hp=020fc338d749be0f8f49d133911a6c33d2eb56a1;p=xboard.git

Make Hoplite moves irreversible in Spartan Chess

Consider Lance moves in variant Fairy (where the Lance represents the
Spartan Hoplite Pawn) as Pawn moves, so they reset the 50-move counter.
