$50 6max: 2 pair with 4 to straight on board

[You're No Daisy]

I would put out a blocking bet of $6 and if you get raised, you can fold. He could have anything here even though his stats suggest a tight range. He probably has a queen here, possibly KQ maybe QT or QJ, but I would expect him to raise you on the turn if that was the case. JT is also a possibility. That gives him an OESD on the flop, a pair on the turn and two pair on the river. Keep the pot small for sure on the river.
