if you are looking to take it down a min raise is not that good here. Like he said above there are too many people behind you that can call or raise. If you would have popped 12000 maybe you would have got the quick folds. Most of these questions dont give enough information. If the other players have been folding to a min bet then maybe it was a good move but A7 calling shows you didnt have a strong table image or he has a tendency to defend his big blind. Then your bet of 8100 when the queen flopped did scare him at all. I think you picked the wrong position, the wrong raise and the wrong blind to attack.
