AK can be a difficult hand to play on loose low limit tables. The reason is you're plaing it wrong. I seriously doubt you're c-bets are going to be respected at this level so the raise, isolate and c-bet style of play is out. What you need to do is raise smaller preflop, something that keeps a few callers in the hand (even 3 or 4 is fine) and builds the pot, while minimising the cost to youself so you can just check/fold when you miss. If you hit play as usuall.
