Commerce Casino $200 No Limit/ $3-$5 Blinds. I was in the small blind hole cards are KK. 6 players call when its my turn i bet out $20. Got heads up with the button. Flopped 9 98 (2 spades) pot was $70 and i bet out $40 button calls and the turn was a K heart. i check to him he raises $40 and i raise him $75 more. Thinks for a while and he folds. Says he had 8 2. The thing is that i thought he initially raised $50 on the turn, thats why i popped it up $75 more... if i actually was paying attention i would have made it $60 more to go for him. i think if i did do that i would have gotten a call and maximaxed the play. He thought i was BSing. what do you guys think?
