The University of Tasmania Physics club way back in the early 1990s was a
place for all kinds of misfits and bearded eccentrics dressed up in full
star trek outfits or medievil battle costumes. Bughouse (known as
transfer chess) was a popular game (along with double monopoly etc) and
was sometime played with six people. A variant of this called Queue
transfer simply meant that the pieces captured were placed in a queue and
could only be used by the partner in that order. Double king transfer
was
another variant in which both enemy kings had to be captured. A team
could
have its first king literally taken. This led to some very amusing
senarios
including a player losing all his pieces yet still being in the game!
Another variant would get all the points from captures that could be
tallied and converted into any piece. A knight was worth 4 points
because
of its ability to attack unopposed. An interesting variant would be to
introduce variant pieces into this equation. ie rook + bishop =
chancellor.
