ICM says your starting equity (if you fold) is about $1290
If you push, there is a 50/50 chance you go bust against a random hand:
Assuming the best case where the SB *always* folds and the BB always calls
1/2 * 1000 + 1/2 * equity with doubled stack
equity with doubled stack = $1550
Equity for moving in = 775 + 500 = $1275
Answer: Pick a better spot!
