Cubs93: Yes, bughouse is most cool, but it don't think it could be played here, as it is to be played only in live mode and with very fast time controls ; otherwise, there are very long and painful double sits (you and your partner's opponent both wait for the other to play).
You'll probably have to play Loop Chess instead (and I think that its close cousins Hostage Chess / Recycle Chess are scheduled for future implementation).
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
