How would you play these rivers and what do you put your opponent on?

Hi All,

Not posted in a while. Would appreciate feedback on two hands.

Stars 1/2 Cash - I have $200. No reads yet as first few hands at the table

Hand 1

I get 88 UTG and raise to $6, 1 caller in MP.

Flop
T 7 2
I bet out $10 and MP calls
Turn is Q, I check and he bets $22. I call.
River is 3, I check and he bets $58.

What do you do?

Hand 2

I have $380 in front of me at the same table.

Villain has just over $100 and is UTG. He has just lost a big hand to me.
He calls, I call in MP with KQo and we have 5 to the flop.

Flop - 7h 3h 2d. Checked all round
Turn - Ks. check, check, villain bets $8, I call and all fold.
River - Kh. Villian bets $12.

What is your move here?

Cheers for all answers. I will post the answers up shortly.

Jon
