$3/$6 HU, I have a set, and yet, no raise?

[Xaston]

Villain loved loved loved to double/triple barrel. He was actually pretty close to being a super tough HU player (I think). We only played about 200 hands together total so it's a little hard2tel. He needs to be able to make a couple more folds, and possibly tone down the multi-barrel bluffing a little. But really, a good very tricky, yet exploitable player.

I have been check calling him on the flop and turn a LOT. Bottom pair, middle pair, top pair. Gutshots. Lot's of check calling from me, and lots of multi barrel betting from him (real hand or not).
