NL10, flopped OESD,

[bozlax]

Converter's not taking the hand for some reason, so I'll just long-hand it:

No interesting reads, I'm a little drunkern and watching baseball while I play.

Key stacks:
Hero has $10.20
MP has $5.20
LP has $3.30

Full ring, NL .10BB

Hero gets 43o in SB. 3 limpers, I complete, BB checks.

Flop comes Q53r. I half-pot (.25), BB folds, MP across from me calls, LP raises to 1.50, Hero ?

Here's my question: I don't really have any idea how likely MP is to call the raise, regardless of whether I call; should I push with 2.50 in the pot, and the flop raiser only having 1.70 left behind?

Okay, never mind, I just answered that question. If I think that the MP will stay in and contribute his remaining 4-something, then I can call but not raise. If not, I have to fold it, as played. Right?

So, second question, should I lead the flop for more than half-pot?
