I overplay AK all the time in the micros because it has so much potential. I think the best way to play it aggressively as possible.
Preflop, you're never in too terrible of a situation.
-You're way only behind AA, AK and you take away some of the combination of AA/KK pairs
-You flip vs all other pairs. I late reg only, so effective stacks are shallow. So, I don't mind flipping for 20-25BBs with AK.
-You crush all other A/X combinations.
-60/40 vs all other non paired hands. (AK vs Q9)
Postflop, you still have a ton of potential
-If you hit, you have TPTK
-If you miss, most flops are good enough to cbet and take down with AK. So, you have a ton of fold
equity.
-Even if your opponent has 66 on a 92Qr flop, it's hard to call a cbet with a small pair. Especially if you raised/3bet preflop another continued with aggression.
-You also have some equity to hit on the turn or river, or if you turn a gut shot, you can double barrel.
Ultimately, post flop play depends on board structure and your opponent, but we only hit our flops about 1/3 of the time and miss the other 2/3. So, your opponent is missing quite often as well. Cbet those dry flops and pick up those pots.
