The open limp stinks for all kinds of reasons, not least of which is that it's virtually impossible to narrow the range of hands your opponents are playing behind you.

After that, what do you hope to gain from the flop 3-bet? IMHO, OOP this pretty much amounts spewing -- although I'd love to hear any insight into any benefits of the 3-bet. If you're worried about overcards checking it through on the turn then flat call the flop bet and lead a safe turn.

When the K hits it's game over. Pretty much the only hand you beat is AQ, and if he bets that then power to him. Check/fold.
