once it gets popped to $30 I for sure agree with the line of raising to Isolate with the pocket Jack's and I agree that flatting is a terrible idea.
I would typically go with a three bet so it would be $90.
the reason why I still would go with the raise is to at least see if the other would fold and if not then lets just see the flop
Flop comes $150 9

V goes all in for $50 and I do believe folding is a bad choice. its $50 into a pot of $150 and all your worried about is a flopped set or a over pair. I do believe a small amount of the time we lose and a larger amount of time we win this call.
Now the other guys that may be in on the draws **** I agree with the other guys comment that we should let them draw and hopefully brick it. I mean the majority of the time the flush or str8 will not get their enough times. So I believe this is a profitable play to value bet the draws all the way down to the river
