Merge has a new HH system and it's not working right now on our hand converter.  But I'll describe the hand, which isn't complicated. 

6 players remain in a 1$ rebuy/addon, the big stack villain has 24BB at 2000/4000/400, I am one of the short stacks with 7BB before my BB is posted.  So far I have only 60 hands on villain, but he is playing 27/21 with 0% open limp, 40% steal. Scarce info on fold to donk bet but he did do it once.

Button: P1: 7BB

SB: P2: 15BB

BB: Hero: 7BB

UTG: P4: 20BB

UTG+1 Villain: 24BB

CO: P6: 16BB

My hand is QJ

Villain opens into me for his usual 9,600 making the pot 18,000. Everyone else has folded.  I don't believe he is so tight here, probably a semi-decent opening range that I am slightly behind.  Pocket pairs, AX, KX, Q8o+, Q5s+, J7s+, J9o+ and some speculative hands.  The problem is I don't think I have any fold equity here preflop, while my hand flops well, and that I do believe I have some fold equity on a flop shove.  I call for 5,600 with the intention of pausing and shoving almost all flops.  If I land quad queens I’ll check. Is this reasonable?

Or am I misunderstanding how to use a stop n go?  I could see if maybe you're only supposed to do this if your stack is larger than the opener's and that his stack looks kind of like mine does here?
