25NL: 3 preflop spots

[Kairos]

I don't know if it's ok to post 3 hands at once, but these are pretty similar and maybe basic, so I didn't want to clutter the forum with 3 threads.

Hand #1:

I just sat down so no reads or stats.

Party Poker - No Limit Hold'em Cash Game - $0.10/$0.25 Blinds - 6 Players - (LegoPoker HH Converter)

SB: $0.42
BB: $27.77
UTG: $7.65
MP: $13.00
Hero (CO): $24.65
BTN: $11.57

<font color="red">UTG raises to $3.00</font>, <font color="red">MP raises to $7.75</font>, Hero?

Hand #2:

Villian runs at 36/14/1.1 over 130 hands, but I think he had more aggressive stats when this hand happened (I had ~30 hands with him at the time).

Hand #3:

This was at the same table as #2 only a couple hands later (I called in #2). I don't know if that affects the decision.
Villian runs at 22/9/1 over 129 hands.
