Huge draw on flop, Stars $25 no limit

What's up guys? I'm usually at home on the Sit n Go forums, but I've built my bankroll up and started mixing in cash lately. I've read Sklansky's book NL Hold em Theory and Practice, as well as tons of forum posts about cash games. I've got $475 built up, which isn't a ton of buyins at $25, but I think I have a big enough edge against most of the players. Anyway, here's a hand I just played I thought was interesting. Marvinho is donkish, he has limped several times in early position and called raises, as well as calling postflop. Do you call here, and if so, what range do you put him on?

Fold pre, fold flop, definately fold now cause hes probably not folding an overpair.

Eaasssyyy fold pre, as played shove because you have 15-17 outs vs. most of his range.

calling pre is bad as others stated as you will just get in bad spots. i think i push flop here though as badgers said. FE plus outs

Fold pre, shove it in now!

dont play this hand vs a early position raise, it gets you in trouble

shove the flop now that u got there

As others have stated, I would fold pre but now I definitely stack off 100%. I don't think 3 betting pre would be good either.

I switch it up between calling and 3betting here, felt calling was better here.

Switch it up between folding and folding preflop.

Shove allin because you are like 50% or something versus KK. You don't have fold equity but getting it in with the NFD against two opponents isn't bad.

Everyone says how bad calling PF is by rationalizing "it gets you into trouble" but no one has taken the time to say why. I guess I will.

The PF call is poor because of how your hand stacks up versus his perceived raising range from Early Position (EP). If you have pokerstove it would be a good experiment to test your hand vs a range of 66+, AJ+. A lot of the hands in his range have you crushed before the flop. It truly does not matter how good you are post-flop when you are fighting such a strong equity disadvantage.
