You're in a 3-handed 30-60 game online.
You find yourself with Qc8c on the button. Obviously, you raise.
SB, a good player, folds.
The BB, a big donk who both chases and bluffs, three-bets you. You call.
Flop is 3h6d7s rainbow.
The donk now checks. You also check.
Turn is 8h, putting two hearts on the board.
The donk bets out. You decide that he probably sensed weakness out of you on the flop, and assumes he's ahead with overcards. You raise, and are happy to see that he just calls.
River is 3c.
Obviously a fold is out of the question, but do you raise or just call?
