There are significantly fewer bughouse openings than there are chess openings. Many chess openings create weaknesses which can be easily exploited in bughouse. It is for instance not recommended to move pawns other than the d- and e-pawns. Bughouse openings are generally geared towards dominating vital squares and fast development. Captured pieces become available after the first few moves and it is important to develop at this stage as there is often not enough time to do so later. Development also helps to defend against early piece drop attacks.
