seems like a very weird hand. Although a tough spot to get into, out of pos with just top pair against a rock, and the fact that you can face bigger bets on turn and river, can you really fold top pair here when getting 4-1 to see another card
Is there any chance that the tight player has 89 0r QK and wants to slow rizen down to induce a free river ( when it goes check, check on turn) or he could just have two random spades and want to see a free river using the same logic.
Also ask ourself this. If Button has a monster set, then why would he do this "Donk" re-raise and give Rizen odds to call incase he is the one drawing to a straight or flush? Just because he min re-raises on the flop, it does not always mean he has top pair beat. Most of the time it does, but not always.
