Is he a reg? It's tough to comment on his UTG range without at least knowing that he's the TYPE who would play tight from UTG.

Anyway, this is kinda a spot where how you play the rest of your range is important. CiB'ing preflop here against TAggs can be good jolly fun, but it helps to have a CiB bluffing range for this to be effective.

As for flop, if villain is a TAgg, then I'm not really fist-pumping all that much. I mean, people are so bad at 4nl (lowest stake on this site, right?) that you'll see a lot of TP2K type stuff, but we're not exactly playing for stacks. I probably call down on most boards and bet whatever streets he checks because we can rely on him to make mistakes with speculative top pair hands and QQ and such. Anyway, CiB/folding against this type of player seems terrible (it's a great way to make them skittish about their hand without actually charging his draws that much, and we're giving him a chance to semi us off our hand).

Again, this is all based on the assumption that this is a TAgg. If he's a fish, then weeee bombs away! Raise flop bigger, and how you continue to a 3b depends on how aggressive villain is post.
