blank on the turn after semi bluff

[digdug]

What is generally the best way to play after a blank hits on the turn after a semi bluff on the flop? For example, you have A[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/heart.gif[/img] in the big blind. There is a raise from early position, 2 calls and you call. The flop is 10 [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/heart.gif[/img] . You check, the next 2 check and the button bets about 3/4 pot. You raise about 3 times this amount. The other 2 players fold and the button calls. The turn is now the 6 [img]/images/graemlins/diamond.gif[/img] . Where do you go from here? Do you bet/check if the other player is loose/tight, aggressive/passive? What are the most important considerations here? What if you bet and are raised?
