I'm a little confused at how Villain could initially call for 50 w/ the blinds at 50/100. But either way I push preflop here. You pick up more than a third of your stack if everyone folds, and of course are likely no worse than a race if called, and you get all five cards. Seems like an easy push w/ less than 7 BB left.

But that's not what you asked about. You have to go all-in on the flop here, regardless of the monotone texture. You have TPTK, and are about a 60-40 favorite over a flush draw.
