Overcard protection or spewage?

Limpers are loose PF and slightly aggressive postflop. No reads on PF raiser.

This is a mess.

1. Pre-flop is probably fine, though realize that the raise if probably not a steal and hence represents a legit hand; translation: one that is likely to be dominating you.

2. Flop check-raise is bad. Think about it:

-The primary reason you might have some dominated overcards is in fact because of MP3, not the others. If anything, loose limpers may be more likely to have hands you are dominating. Hence, check-raising really does little but get you heads-up against the one person who is most likely to have you in bad shape, while encouraging the likely dead money to fold. You are not clearing out the A [img]/images/graemlins/heart.gif[/img] obviously.

-Check-raise is not for value, as you're likely making the pot two ways and often if it is not it's because you're basically drawing dead.

-Check-raise puts you in a tough spot on the turn often, since betting opens you up to a raise and checking is unlikely to allow a free card but does expose the quality of the hand.
