Given your stack size I push preflop, if there is another call then you have less than 1/3 of the pot on the flop so you have no real decisions postflop and your opponents will know that. If they are going to call that raise PF they are going to call your push a good percentage of the time, Id rather get it in as a favorite preflop than not being sure where I am on the flop but with no real choice.
