I was playing in a low stakes s&g this morning. I had around $2500 chips and was in the BB. My opponent was second in chips with $2300 and was UTG plus 1. After the first round of betting we were heads up. There were 8 players left. Blinds were 50/100 with no antes I had AhKh. My opponent made a standard raise of three times the BB. Everyone folded to me and I called. The flop came 7hTc3h. I have a heart draw and because of the betting patterns of my opponent I put him on a small to medium pair or an Ax. I bet $650 as a pot sized raise expecting to run him out and steal the pot right there. He had buckled several times with apparent steal attempts. But he reraised to $1300. I should have retreated right then, but no, how could I fold this 4:1 shot. Well, the pot, now $2600 (650 + 650 + 1300) is only offering 2.6:1 but I didn't calculate the odds and just shoved. He called and turned over AA. The turn and river brought me no help at all and I was down to my last 200 chips. After I busted out on the next hand with AQ off I sat down with Harrington on Hold 'em and read a section on reading the board. Lo and behold, there it was in plain English. When a tight aggressive player comes over the top and you are holding a draw such as AQ suited it is a clear indication of a very high pair and it is best to fold and live to fight another day. I misread the situation, one that cost me any prize money, a misread I am not likely to do again soon. If the hand had been an AQ suited in the same situation I most likely would have laid it down as I tended to overplay those two cards suited or not. I learned to make that laydown but I didn't equate the laydown to big slick. Hard lessons lead to improving one's game. If I had laid that down I would still be playing and not writing about that bone headed play.
