Hiya,

I'm new to SnG. Used to play in the past (~10 years ago) and just getting back into poker as a hobby. Used to play cash games but have found I have really enjoyed SnGs lately.

Any advice on lines here would be appreciated. Tournament poker/SnG are very unfamiliar to me at the moment so any general advice would also be well received. I don't play with a HUD but have these observational notes:
UTG+1
Has a med VPIP PF during the early/medium stages of the SnG (~40%)
PF R % seems to be < 10%

No notes on CO

Situational notes:
This is the 3rd hand in a row I have isolated UTG+1
UTG+1 folded flop to CB in past 2 hands

How do you approach this spot? The turn J I thought was interesting as it seems to fit everyones ranges. I feel like we are ahead here still a good amount of the time, but again the J seems to help everyone or improve their equity.

Do we just jam here? It seems like if we bet anything here and get called we are shoving/calling any river given the odds we will have. Checking behind seems like given my opponents a chance to realize their equity for free but it seems like a spot where we might control as well?

Again any feedback would be appreciated. Thanks.
