AK play quideline?

[Steve09797]

playing AK in late position i find myself playing it the same way everytime no big cards or straight or flush draws are on the board. for example if the hand looked something like 249 6. i know a straight is possible here but let me get to the point im trying to. i will bet the flop, and then bet the turn, looking to probably check the river if its checked to me if no cards come that could help me. anyone have other suggestions on this?
