I´m near the prize money in an online 600 buy in tournament, with about 50 BB. SB-BB are 1000-2000, ante is 100. Chip leader is on the table as well, with 120 BB. I have just been moved to a new table and know nothing about my opponents. I´m in MP with AsQc and raise to 6500. Button and BB call. They both have around 60 BB. Pot is now 21500. Flop is AhJc5c. I bet 13000. The button raises to 30000. I folded....but where can I improve, e.g. minraise or just call pre/flop, check on the flop, call or reraise the buttons raise?
