2 River decisions against same loose opponent.

[Fantam]

I cant seem to get the converter to work, so I am typing these 2 hands out.

They were both against the same opponent, who seemed to be a bit loose, but I had not been at the table very long, so did not have a good read.

Anyway here are the 2 hands, Party Poker $.50/1.00 (both hands 8 handed).

Hand 1: Hero in CO with As,Ah.

2 folds, MP1 raises, 1 fold, Hero 3-bets, 3 folds, MP1 calls.

Flop: Jd,9h,4h (7.5 sb, 2 players)
MP1 checks, Hero bets, MP1 calls.

Turn: 6d (4.75 bb, 2 players)
MP1 checks, Hero bets, MP1 calls.

River: Th (6.75 bb, 2 players)
MP1 BETS !, Hero ....?


Hand 2: Hero in SB with Ad,6d.

UTG+2 calls, 2 folds, MP3 calls, 1 fold, Button raises, Hero calls, BB folds, UTG+2 calls, MP3 calls.

Flop: 8h,Qd,Td (9 sb, 4 players)
Hero bets, UTG+2 calls, MP3 folds, Button raises, Hero calls, UTG+2 calls.

Turn: 8s (7.5 bb, 3 players)
Hero checks, UTG+2 checks, Button bets, Hero calls, UTG+2 folds.

River: 9d (9.5 bb, 2 players)
Hero...?

What do you think the best river play for both hands would have been ?

Was it worth raising the river in Hand 1 for value ? Bet or check/raise the river in Hand 2 ?
