2/5 NL at MD Live and table just started maybe 15ish minutes ago and no real reads/history with anyone.

Hero: Sitting with ~360. Only really played one hand so far since table started, raised AK from CO to 25, got two callers and Cbet 40 on missed flop, both fold.

Pre: 5 limps to hero on button, I call with 75o, BB raises to 25, 3 calls, I call.
Flop: J75 rainbow. BB bets 35(~400 behind) and seems fairly confident, fold, fold, raise to 100(~300 behind) , I shove.

I don't think I played this right pre or on the flop. What would you have done? I'm really thinking flatting might have been best or possibly min-raising, but potentially seeing the turn multiway with bottom 2 didn't seem very appealing at the time.

Villain stack sizes?

Why so short?

Call pre is pretty bad the first time, but atrocious after the raise. I know, I know, "pot odds tho!" You have rags and are putting in 9% of your stack pre. You need a miracle flop to make this profitable.

AP: Look, a miracle flop. BB bets 35 into 125, lool. Someone raises for you. Board is dry and you want BB to come along. I like a flat here, with a plan to gii OTT. Three way is not a disaster here. min-raise is lool with only 160 back. flat > shove >>>>>> anything else, imo.

Short stacked because I was in for 1100 and decided I'm not comfortable putting more into play and decided to move to this new table.

Agree with this.
Don't mind a shove that much, shove is a close second.

Well, you definitely needed to let it go pre-flop. However, since we're here in a $135 pot with $325 left, there's almost no way your money isn't going in that pot and nothing you can do about it. We don't have a read on said villains, but I'd say you are probably ahead here. This is one of the better boards you could have looked at for flopping bottom two pair.
