if you check/call the river on this board, what do you need to bet? A set or better? Seems too weak to me...

TPTK and overpairs need only two value bets without a read. For exactly reasons like this.


Edit: you dont want to play a big pot oop with unimproved overpair. In position you can value bet that river or call if bet to.

Edit2: it should be obvious why you dont want to play big pots oop with vulnerable hands..
