WotC is running their "favorites of the lat 400 issues Dragon" still and one of the ones popping up today is one of my faves from issue #100, Dragonchess.
Gary Gygax, a well known chess fan, created Dragonchess. You can read about it on Wikipedia, or if youhave that DDi thing, then read about it in Dragon #400. So interesting background from Kim Mohan is included too.
My DM back in High School made a Dragonchess board. He used plexiglass and painted a bunch of chess pieces and bits from other games for all the pieces. The paint was still drying when we played our first game, which took all of our D&D time I recall.
Might need to show this one to my kids too. They love chess.
