bet all 3 streets with top 2

I guess I'd shove here. I'm not super excited, but we block the sets, do fine against other K7s (two better pair outs and backdoor stuff) and there's just so much out there that I'd be very happy to win it now if at all possible (unlikely though). I'm further influenced into shoving by the fact that our hand gets weaker on a ton of turn cards but we'll still struggle to find a fold given the price and potential ranges of villains so it'll be simpler to put it in now.

Also, BB probably isn't trapping here so he should be folding his very likely AA (or calling off behind, but I'd rather he folded) meaning I'm only really concerned about SB, but he can't really have enough sets to make this a bad spot for us. So yeah, shove hoping people fold but knowing it's fine if they call (and expecting to get called the vast majority of the time).

o i thought he was sb and cannot shove but bet, yup, shove :)

Agree with just shoving here.  Not super excited about it, but it can't be all that bad either.  By just calling you risk making mistakes on the turn, whether you get it in or fold.  And you most likely have enough equity against their ranges.  So just get it in. 

What's very possible to happen here is that either one of them folds, or they both get it in but one has a hand with very little equity, like naked AA or bottom 2.
