Warmup flop bluff

[Exitonly]

ok, 50 hands into the Warmup, i opened a few pots early on but took them down with a flop bet, hadn't played a hand for about 10 hands and then I opened in MP1 and it slowely folded around and I took down the blinds, then this is the next hand:

is this FPS? Should i bet this flop? I would have heads up, but 3 way with a button caller i check here a lot.

edit: no specific reads, BB is taknaptoin but he's not really involved in the hand, button hasn't done anythign noteworthy (i should have taken a look to see how he lost his 2100 chips, but i think i woudl have noticed anythign atrocious)
