$0.10/$0.20 Online Cash Game. Effective Stack = $20. Hero has 4h5h on the Button. Folds to Hero who raises to $0.50. Small Blind 3-Bets to $1.30. Hero 4-Bets to $3.25. SB calls. Flop = 4d9d6d. SB checks. Hero?
With no reads, should Hero bet for protection (if so, how much) or check behind? Any advice from PioSolver experts would be greatly appreciated. Thanks.
