[yourface]

both villains seem not to be very showdown bound at this point. button has a very low WTSD over a sizable sample, and SB has been playing fit or fold. they would certainly peel with a FH draw, but I thought these guys could probably let go of a pair

I thought that checking may win the most from their entire ranges. we may pick up extra bets from weak flushes when we c/r, bets from bluffs, and bets from pairs that would have folded the turn now call the river

the thing that worries me about checking is that SB may be playing passively with a weak flush or 2pair and I want to get some value from this hand. also button is less likely to bet his set/2pair again or take a stab in a multiway pot
