15-30 hand #108 - KK on the button, down shift?

[Coilean]

Getting 18:1 immediate odds to close the flop action with a call (and probably another 6:1 or better in implied odds), you really don't even need the backdoor draws to stick around. The backdoor draws coupled with any chance of having the best hand should certainly swing this one from a close call to an easy call on the flop, though.

A flop 3-bet might work for getting to the river cheaply in many live games, but I think on Party many players will happily cap it off with an AJ or better and then lead the turn, so I would just call and see what the turn brings.

Checking behind on the flop here seems like an option as well, since you could pretty easily be drawing to 2 outs (plus your backdoor shots) or have your opponents drawing to 2-7 outs (plus their backdoor shots) between the two of them, in some bizarre multiplayer variant of the ole way-ahead/way-behind scenario. The main danger of this play would be if you induce the SB to bet a worse hand on the turn and UTG raises, leaving you in a real quandary.
