I am in MP with KKQJ in a 50 PL o8 game. Maniac player makes it $2 I think about reraising but decide to call and see a flop. I flop my set with 2 low cards on board. I bet the pot and get called by the maniac. The low hits on the turn he checks and I check behind him. The board pairs 6's on the river. Maniac pushes $15 I just calling thinking if he has any two low cards we chop and I didnt want to lose any more to the rake. Turns out he has AA88 and made a smaller boat. I could have taken another $20 from him if I reraise. Stupid play on the river to just call?????
