On the one hand, the button suddenly coming to life and 3-betting after a bet and a raise should signify huge strength. On the other hand, the pot is getting quite large. What would you do?

-TW

Not have raised the turn, that's for sure.

Yeah, granted that was another thing I wasn't too sure about...but considering that I did raise the turn, what do you do now?

Fold to the button's KT?
