good time for a check/call?

[Schneids]

10/20 6-max.

When first in, MP is a frequent raiser, with possible hands ranging from JTo, on up, and have seen Axs raised by him as well. Plays aggressively when shown weakness, but tends to back off more when played back at unless he has a strong hand. MP raises this hand, and I am in the BB with K [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/heart.gif[/img] His postflop play is pretty easy to peg down, so I figure I'm giving up too much here by not seeing a flop. I call...

Flop: [ 7 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]]
Check, bet, raise, call.
