Hand 1 [400$] 5-H

I pick up in CO, folded to me I make it 15 (full stack). Both SB and BB calls.
They are both lose with stats around 45/15, and have me covered.

Flop [Td] (45)
SB leads out 25, BB calls, I raise to 75, only SB calls. Too small raise I guess. What to bet?

Turn (220)
He checks. I have a 290 left. Hero???

Lets then say that hero doesn't know what to do and just before he times out bets 1/2 pot and get called.

River (454)
Checked to her who now has 175 left. Hero??

Hand 2 [200$] 5-H
I have in CO and open to 7, button minraises to 12, I reraise to 32 he calls. I started the hand with 240 and he covers. Villain has the fantastic stats of 47/17 but no other reads.

Flop (67)
I bet 45 he calls.

Turn (157)
I bet 75 he calls

River 307
Hero has 83 left and??

I couldn't put villain on a hand?

Input appreciated!
