The official rules of Asean Chess are like standard chess except that (1) the bishop moves one step diagonally in all directions, or one step forwards and (2) the queen moves only one step diagonally. The pawns promote to any piece (except king) on the eight rank. Stalemate is draw.
In the beginning the bishop is clearly weaker than a knight, but can in later situations be more valuable than a knight. Although the bishop is slow, it is suitable for giving mate.
The Laws of Asean Chess were adopted at the ASEAN-Chess Council at Bangkok, Thailand on March 14, 2011. The variant is a combination of Thai/Cambodian Chess and Western Chess.
In an alternative variant, the King cannot move away from check. This threat must be handled in another way. This faster variant is inspired from Makpong, a variant of Thai Chess (Makruk). It is a suggestion by me.
