Apologies to any1 hoping to find out what the other fella held. Next time I post a hand analysis, I promise it'll be one where my opponent's cards are revealed. Scout's honour.
However, I think it was still worth me sharing this hand with u guys. I reckon flopping a set is one of the most crucial parts of cash game play. These are the hands where you need to extract maximum value, so working out how to play them is vital. Do you bet it, check it, reraise if he raises, etc? Ooh eck. God knows!
By the way, I reckon he had

As. At first I thought he was playing

passively because of the dangerous looking flop and turn, but I believe he would have called the river if had the overpair. Plus, he passed relatively quickly, which makes me think he was drawing.
My belief that he had an overpair was why I bet each time. I was hoping for a reraise that never came.
I can't see him raising to $12 preflop with rags. Granted, there was some loose money from the limpers, but rarely is it worth sticking in a chunky preflop raise just to pick out the spare dough. Too often you get a caller, like me!
