2/3 600 cap game, 7 handedI have about 1900 behind, many players with 150-200 BBs
3 limps to me on button with 85dd, open to 24, sb calls, and 3 limpers call with 550, 700, 400, 250 back respectively,

SB and I have tangoed earlier where I open KQhh for 18, he 3b! 40 on button with 900ish behind, I checkraise his Cbet on a 789 2 heart board and got there for all-in pot on turn because it hits my preflop range way better

Flop (120)
8c7d5c,
checks to me on button
With infinite ranges for these villains, what is the proper sizing to protect yet get value?
I overpot 125
SB check raise to 400
Folds back to me and I tank fold
Preflop should be a fold, but as played, should I just check flop? Bet smaller on flop? Call this raise from a tilted opponent?
