The SB is 21/17 over 25 hands. The HJ I only have 5 hands on but this is the first time he's not folded pre in those 5 hands.

The flop seems a pretty sick spot - when the SB jams, I guess I can just fold, but getting like 3.5:1 I wouldn't be folding if it was heads-up with him. Although I have not many hands on him, I'm concerned about his hand because I expect him not to feel like he has any fold equity here.

I don't feel like I can call either, because I won't have enough left on the turn to make a meaningful bet if the HJ is drawing, and if I call I give the HJ like 4:1 to call.

So I think I can only jam and hope the HJ (who, remember, is an unknown) wouldn't have flatted a set on this board. I don't expect I can get called by worse too often, although I do give him 2:1 even if I jam. I can never fold out better, so I don't want to jam, but anything else seems worse, and the HJ's line doesn't look so strong either.
