[MadScientist]

Ghetto Superstar, with tats and lots of bling, limps UTG+1, I raise to 25 in CO. SB calls. He calls.

SB leads for 50.
GhettoSuperstar announces all in under his breath but doesn’t follow through. Barely audible. May have got reaction off me, prolly. GS calls.
I raise to 225. The last big play that anyone saw, flop 9s Tc 3s, I have Qs Js UTG, I c/r MP and two callers pot to 400 2x overbet and force everyone out, they don’t see my hand obv.

Dealer is being a tool. Has a fill that just came. Is [censored] about with things and stalls between flop and turn. Ghetto Superstar says, “You want to see something?”. I pause and consider if I want to see something and how I will react to what I might see. Also, I am pretty sure what will turn up right now.
He repeats it.
I say “Sure”. He checks and then flips the top card face up A[img]/images/graemlins/diamond.gif[/img].
The turn is the 4[img]/images/graemlins/club.gif[/img].
He takes a bill and bets 100.
I pause and flat call. I will leave my thought process out for now. However, I will share that I thought the river was the place to make money from the moment he said “You want to see something?”.
The river is the 5[img]/images/graemlins/heart.gif[/img] completing straights, but I thought that irrelevant.
He checks to me. I pause and think. Pick up some bills and bet 200. He jacks it to 700. I should do what?
Thoughts on all streets would be appreciated.
