[Dire]

I'm not too fond of playing this spot incredibly fast. Fish seem to be scared of two things, flushes and aces. He may scamper off with a lone pair if you play this too fast.And for all you know, he may actually be making a 'play' with Q or K of diamonds, in which case another diamond actually isn't a scare card but the card he's fishing for. I would probably call the flop, planning to raise alot of turns unless it looked like somebody else was going to get the money in for us. It's completely transparent, but it doesn't matter against this type of player.

As played I make it $120 on the turn. It's a very small bet that's easy to call and will leave $160 for the river into what will be a $500+ pot.
