villain was thinking and slightly loose. running after draws calling rather light.

1. call turn is bad or borderline?
2. would you bet this river?

Fold turn. You have 33% odds to hit your outs (2, 7, T), and some of them might not even be clean if he's on a flush draw. He might also hold some of your outs himself, and you can't know if Tx is even good. So in reality, your odds are probably closer to 15%.

Hand 1 seems like a standard get it in. Hand 2, bet less on flop and fold turn imo.

hand 1:
Given from your other posts, you're a minraiser and were having trouble against a spewy villain last night.
I've been playing the same strat, and I find that hand 1 comes up very often, in which I think "what could I seriously be getting it in against deepstacked that I have beat?"
The answer at $10 HU SnG (also the stake I'm playing----we have a nut-TON in common) against a spewy player, while playing multiple games against someone with a minraising strategy:
I dunno...like Q high dude.

You're perfectly okay to be getting it in here. I've been meeting with a lot of random spew from some villains, and if this villain is proving himself to be a donkey (what it sounded and looks like from other posts) you CAN"T be folding TPTK.

Hand 2:
fold turn.
Betsizing on flop is fine IMHO.

2nd: flop is ok though I would bet a little smaller. On the turn easy fold, you've no implied odds to call, even if you hit one of your outs on the river, it is unlikely that you'll be payed off by some pairs and even 2 pair hands. because all your line looks like draws.

sorry hand 1 i did not want to post...

yep - hand one i did not want to post here...

i dont know what u mean with: The answer at $10 HU SnG (also the stake I'm playing----we have a nut-TON in common) against a spewy player, while playing multiple games against someone with a minraising strategy:
