Castling on opposite sides
Playing with opposite castling is fundamentally different from one-side castling. When we castle on the same flank, we mainly develop our attack with the help of pieces: pawns are rarely involved in this case. It is quite different when we castle opposite way: here the attacker could push his pawns forward. Such a pawn storm with the opposite castling is the typical strategy: the pawns are "cheap" chess material, and is most advantageous to use them in order to destroy the enemy's position; even when we have to sacrifice pawns, that is done to achieve open files for our heavy pieces - Chessworld.com
