re: Poker & $2 NLHE Full Ring: Shove with AK on 2Q3 board?
I think the preflop action was the biggest mistake in the hand. Your initial 3bet should have been much bigger. Your goal in this spot should be to play against one opponent. Since 2 players limped in before the villain's first raise, your 3bet needs to be much larger. The rule of thumb for 3betting is to raise at least 3x the size of the opening raise and you should add a little extra for every other player in the pot. (So in this case somewhere around 17bb-20bb.) This way you can discourage the limpers from calling with mediocre hands because they will be getting terrible pot odds
Once the villain 4bets to 20bb, you should probably just go ahead and move all in. If you just call the 4bet, the pot will be about 45bb and you are almost never going to fold on the flop no matter what the cards are. If he moves all in on the flop, you will be getting about 2.5 to 1 pot odds
and I'm calling that with AK all day long. By just calling the 4bet you are allowing the villain to see the flop before he decides to go all in. He may see a terrible flop and decide to hold on to his remaining 30bb.
Obviously if you both got all in preflop, it would not have made a difference this time. He would still get lucky and win the hand. However, if you had moved all in instead of calling the 4bet, he may have folded. Basically, keep the pressure on when you think you are ahead. Don't give the villain an opportunity back out if he misses the flop.
