Okay, so this was my first full session in about 4 months (I hope you folks missed me!)and I was definitely feeling a little rusty. Here's some questionably played hands for review.

Hand 1:
Party Poker
No Limit Holdem Ring game
Blinds: $1/$2
6 players


Stack sizes:
Hero: $238
UTG+1: $246.10
CO: $264.34
Button: $205.80
SB: $198
BB: $64.20

Pre-flop: (6 players) Hero is UTG with
Hero raises to $7, UTG+1 raises to $12, 4 folds, Hero calls.

Flop: ($27, 2 players)
Hero checks, UTG+1 bets $15, Hero raises to $45, UTG+1 calls.

Turn: ($117, 2 players)
Hero bets $85, UTG+1 calls.

River: ($287, 2 players)

What should I do here? I'm not laying down to a bet. Should I check to induce a bluff in case he has a busted draw?

Hand 2: Opponent seems to pretty loose, but no real read on his aggression.

I called on the flop thinking that he had an overpair. Filling up on the turn was not my intention and kind of surprised me, should I have check-raised the turn or bet smaller on the river?

Hand 1, you only have $100 left so just stick it in. For one, he won't think he can bluff you off this pot for $100 into what would be a $400 pot. Second, he will check behind his marginal holdings and bet his strong ones. So you'll be losing value against his marginals and still paying when you're behind.

Hand 2, looks fine. I'd kind of prefer to 3bet the flop though since you're OOP and there's oh so many cards that kill you or kill your action.

Hand 3, I might consider getting more money in on the turn by leading. I doubt he'd believe you have a 5 or a boat, and probably put you on a steal from a semi-scare card. I think he'd have a tougher time getting away at that point than if the river came 4-straight or something. But your line is fine too.
