I find it amusing that you of all people appear to be implying that I'm being overconfident, Rob.
- You gain extra fold equity by pushing.
- You eliminate any second-guessing of yourself postflop (I know I said you'd be committed, which you will be in the vast majority of cases, but if 9dTdJd flop and you hold AsKc and villain pushes, you may end up folding).
- Most importantly, pushing preflop ensures you are getting all your money in while either ahead or coinflipping
(barring villain holding AA/KK, and considering the range for a SB raise here is huge, AA/KK is unlikely), a situation that will true a lot less of the time if you see a flop, considering that AK misses more flops than it hits. Why get half your money in when you're almost certain to be flipping or better and the other half when in most cases you won't have a clue where you stand when you can get it all in while you're more confident of your chances?
Say you repop to 3.5k and villain pushes, do you seriously consider folding despite having half your chips invested and getting ridiculous pot odds
that I'm too lazy to work out exactly? Unless I have some kind of read on villain as the tightest nit in the universe, there's no way that should happen as far as I'm concerned.
