Help... high cards

[x3m]

Hi guys, i play mostly NL cash games and i noticed, that i often don`t know how to play two high overcards, like AJ, KQ,... (not pairs) when i miss the flop. I wonder, what is the right play for this, when you miss the flop and... a) you are first to act? b) everyone check and you are last to act? Another similar situation is, when i have high pair (TT, JJ,...), and there is one overcard on the flop. Again, what to do when... a) you are first to act? b) everyone check and you are last to act? c) someone bets something like 1/2 the pot and you are last to act? Thanks for your answers :ok GL, H.

Re: Help... high cards some more information would be nice, such as blinds you play and whether you play short handed or full table.
