Sigmund Wellisch, 1912. Three-handed hexagonal chess. This was among the first of the successful three-handed chess variants.
Whoever captures the first king commands that army. Afterward, the game is won and lost normally. I made all pawns promote to queens. Sigmund Wellisch, 1912. Instead of the capturer of the first king acquiring the defeated army, I implemented the simpler rule that this player wins and a draw is counted for the player who was not checkmated. I also had all pawns promote to queens, though Wellish allowed only promotions to a previously captured piece.
I've been having some trouble with the promotion stuff.
These are simple illustrations rather than strong opponents.
