UTG is LAG maniac 33/20

Uh, this is LAGgish, but nowhere near maniac. We also need postflop af, plus maybe tell us about some other hands he's played (on what street was he raising a mid-pair...if postflop, what was the board, etc.).

But, your read is that he's a nutball...so why do you slow down on the flop and turn when you've got TPTK with no flush or straight possible on the board? This is total weaksauce given your read. otoh, you cap the river when you make trips but he's hanging with you. Once the board pairs and he's still betting into you, you've got to at least consider that he's playing KJ, a pair of deuces or treys or whatever.

So, nutshell: you're completely ass-backwards on this hand, and your "read" might as well be no read at all in terms of enabling us to analyze your play. Welcome aboard.
