I think pre is fine. 3bet if ds.

On flop idk if I should be leading into 4 people here.

I'll go first for what it's worth.

Against reasonable opponents there are only two probable calls (sevens full and anyone with the other nine not yet full). The only raise would be against someone holding 97 and even there they may wait for a safe turn to raise. OTOH checking might induce a late position bluff or a thin bet with a wrap, much of which you block. If it gets checked through you probably have the only nine. If you check and there is a bet and you could still be ahead (especially against a late position bet) or against a weaker 9. Of course you could be against ace/9 but your not in bad shape with over cards except the ace likely outs or improving your hand (the ten gives you a wrap).

The risk of checking (and it gets checked through) is the turn coming an eight or ten or six or a small card that fills up an opponent that wouldn't have called the flop wager. It could also fill up an opponent holding an overpair of one of the side cards you have. But it has the advantage of getting later calls you want from weak nines (or an ace nine) if you can spike a full on the turn.

I think it's close and in game I'd tend to bet about half pot.

Bet 1/3 no one has a nut advantage here.

Fold pre unless you have a specific reason/target to call here especially if it's not K suited.

Pre seems close to me in a high rake game and with two no-reads yet to act. On balance I think fold is best but understand calling arguments.

As played, I think we can have leads on this rank of pair and three overs is a great combo to do so. Bet small, like the 1/3 suggested.

It's live, time rake.

The two no-reads are very very likely just calling unless they have AAXX.

Pre is fine. Zero chance I am folding this live with time rake, unless UTG is known to squeeze a lot from the straddle. I like 1/3 to 1/2 pot lead out.
