This guy is pretty strange, but seems to be tight enough to fold vs 3 barrels Tx-. How realistic my assumpiton?
I know the turn card is good for us, and the river card isn't. Should we bet blank river then?

2 hands before I was stealing on sb vs his bb and just check-folded paired board with similar structure.
How good my bluff is? What do you think about bet sizing?
