I hate top pair mid kicker

Even if Hero is behind - which I don't think is automatic - to the hands you suggest, he has a decent number of outs to call the turn raise.

Villain called in MP3 after MP2 had limped. If he's loose and aggressive, I think we can safely rule out KK and AK, and probably KQ and 99. So, it is possible Hero is drawing dead to 77 or 22; plus drawing slim to K9 or KJ. However, Hero has outs against all possible 2 pairs:

K9: 3 tens = 3
K7: 3 tens, 3 nines = 6
K2: 3 tens, 3 nines, 3 sevens = 9

97: 2 kings, 3 tens, 3 twos = 8

If Hero is behind to KJ, only outs are the tens = 3

Pot is currently offering 1:8, which is okay especially considering you might even be ahead.

I'm still calling the river bet. I think you're good here more than 10% of the time.
