I actually like the enormous over bet in hand 1 against weaker opponents.

If you raise to 15 then it's 10 more for him to call. You need him to call that 4x more often than raising to 45. Anyone with a hand good enough to call 10$ more is at least 25% as likely to call 40$ more in my opinion. You guys are all looking at the results here i think more than the play itself.

Hand 2 is fine if GMM guy is passive pre flop. I don't want to wind up in the middle of these two with JJ if he decides to push over.

Hands 3 i want a read on my opponent, UTG min raises are scary because they don't make sense. I probably reraise preflop and let him define his hand more. I don't want to flop TPTK and wind up having to make a difficult decision against a set.

Hand 4 is good.
