shoving is pretty much the worst thing you can do in the early game, it gains you very little in terms of EV, you are often behind or flipping if called and it will cost you to lose a lot more games early which costs you later where the real money
Think about this example.
Early on 15/30 and you jam 1500 chips to win 45 chips, that makes absolutely no differance at all.
Now at 100/200 you jam 1500 chips and you gain 300 chips, which is a huge boost to your stack at that stage.
So thinking about that, do you think it's better to not get involved as much early? Do you think it seems like a good idea to risk all of your stack early for 45 chips?
So long story short, just come in for a raise and see what happens, if you get 3bet, just fold it, no big deal. If someone calls just c-bet if you miss or hit and go from there. Don't be afraid of going postflop with someone, it's only AK, you can net more profit in later spots by jamming 92o than you can with AK early.
