Initial position.
Breakthrough is an abstract strategy board game invented by Dan Troyka in 2000 and made available as a Zillions of Games file (ZRF). It won the 2001 8x8 Game Design Competition, even though the game was originally played on a 7x7 board, as it is trivially extensible to larger board sizes.
