First of all, I’m thinking you should make your 3bet a bit bigger. With a raise (I’m assuming to 90) and a caller already behind, you are begging to go at least 3 way possibly more into this pot with implied odds for anyone at the table. I’d make it over 300 maybe even as high as 340 just to discourage ppl with that many players left behind. You essentially min 3bet here and with no antes and approx 170bb stacks all around you aren’t pushing anyone out. You would like to get heads up with the original raiser or caller if possible. This will also give you more control of the hand and a better sense of his range (though many players may call anyway this deep).

As far as the flop goes, it gets a bit interesting. The OR checks, so I’m not too concerned about him unless you get a big chk/r indicating a huge draw or a set. The caller makes a fairly large bet, but considering stack sizes and stage it isn’t uncommon. He has some sort of hand, JT, QJ, KJ, AJ, KQ, are all possibilities along with a wide range of spade draws, though I don’t know if he bets out with the flush draw. Readless it can be hard to know what he does with a flush draw.

I would choose to raise his flop bet (to ~1k or so) to find out where we are and to try and take control back. Calling seems pretty weak since we were the original 3bettor. If he shoves we can be pretty sure we are either in big trouble or flipping so we may be able to save some chips. This early on this type of board I don’t how happy I am getting it in with him.

If he calls our raise we now have control again and can re-evaluate on the turn. This may also get us a free turn card if he has top pair or even two pair and the turn card is a bit scary. Or if he was on a draw we can push him off it if he misses, tho I assume big draws get it in on flop if we raise.

As played, I’m pretty torn, readless I find it hard to get it in here with one pair facing a big turn bet. He is not folding to a shove and calling is bad. The fact that he called an OR and your 3bet he has such a wide range. Sets and two pairs are def a possibility and you are in terrible shape against them. I doubt he leads out turn that big with just top pair and def does not with a flush. Fold and note the hand. I could say more I gotta run. Hope this is helpful.

Yeah don't raise to 'find out where you are at,' thats stupid and not sure why I wrote that.  Looking back it might be fine to call flop and see what he does on turn.  His turn bet screams a big hand though, so definitely a good fold.  The only real problem I see is to 3bet bigger preflop.
