Live 5/5 Hand - playing AK on the flop

[coltrane]

5/5 NL - my stack is short at $500 - table has me covered

I haven't been at the table long, but every player seems pretty competent....


Preflop:
I have A [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/club.gif[/img] in the SB....MP makes it $15 to go (this amount is more of a potbuilder at this table as opposed to a "raise")....two people behind him call....I decided to just call here and play a smaller, multiway pot.....I didn't want to make a big raise because I didn't want to have to play a big pot from up front if I didn't flop to it.....(anyone disagree with that last sentence?)...

Flop ($60):
A [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/spade.gif[/img]

I lead out for $60....one caller in LP - I have no read on him....

Turn ($180):
7 [img]/images/graemlins/diamond.gif[/img]

what's my plan here?....easy check/fold?....bet out again and fold to any further action?....

by deciding to play a small, multiway pot am I pretty much resigning to the fact that I'm giving up a TPTK hand if I get played with?.....or does it depend on the board?....and on that board, am I pretty much shutting down after the flop if any diamond (or even a possible straight card) hits?.....
