Ok..so I had been playing 1/2 at the Venetian for about two hours. The table was a pretty good mix of characters....with an Asian young man two to my right. I had not seen him get way out of line or anything...but then again he was very aggressive post flop and forced a lot of folds so I did not have a well defined range. Anyway....I get pocket 10 ' s in the small blind. This guy raises to 10 in the cutoff. I call as does the big blind. Flop is K/ J/x...and it checks around. After he checks...I am thinking....well....I am ahead of A/Q.....so I waited to see the turn. Another blank small card rolls off.....but I couldn't pull the trigger....so when the guy bets 15....I fold. At the time..and l I could put him on was A/x. But looking back..he could easily have had a smaller pair than I did. My question is how best to play on the range of possible hands and not get so focused on specific hands. What are some mental exercises to go through so you think rather than just react?? Thanks!
