re: Poker & $2 NLHE Full Ring: Should I 4 bet pre? and fold to a 3 bet on turn?
4-bang it pre, fistpump. Why? Because AK is a ****ing good hand and your opponent sucks. Its that simple.
But if you want to get technical, its because when you hit a flop with AK, all the hands you beat in 3-bet pots tend to fold. So calling to extract value when you hit isn't a profitable strategy. Its better to 4-bet and get all those hands with good equity against you to fold. Or in this case, against this opponent, you can probably also get him to do some dumb things with AQ, JTs, whatever pretty thing he's holding.
Also, don't fold postflop.
