---

PRE-FLOP - I had to reraise here because there was already one caller to the original raise and if I just called the limpers would have come along anyway. Apparently my reraise scared them all, didn't it. [img]/images/graemlins/frown.gif[/img]

POST-FLOP - I have an overpair with a scary flush draw on board and a lot of opponents saw this flop so I wanted to come out aggressively. The first reraise didn't bug me but the second one did. However at this point I had to put $17.33 more into a pot to win over $100 so I felt like it was an call even though I might be behind to a set but I also might be ahead of AJ and a flush draw. When the Club fell on the turn, I hoped that won it for the main pot and not the side pot.

I shall reveal the hands after my play and reasoning gets critiqued.
