Both villains are tight player. Im effective stack at $500. BB 95% does not bluff. Just a question of what is bottom of his range for betting.

Preflop was planning on back raising. Sat down 30 min ago, played 3 hands, got 3bet on two of them, so pretty aggro table. I dont think this combo raises flop Mw.
