Late at a 5-table SnG. Button had been raising quite a lot. Didn't feel like raising him though, as KQ doesn't really do well against his calling range, which, I believe, includes lots of Ax's and PP's. Didn't feel like folding as pot-odds are good and hands like this don't come round that often when 5-handed. M is getting too low to wait. Elected to call and re-evaluate on flop. Not worried about UTG who's never limped with strong hands.

Did I make a mistake pre-flop and what's the best line to take on flop?

The pot is huge relative to our stack size, our M is rather low and we have a good hand. You've got an aggressive button and a donk limper, we have good fold equity and a reasonable chance of having the best hand against their likely very weak ranges.

Shove.

As played, we've flopped a good draw with as many as 14 potential outs, any reasonable bet is going to pot-commit us.

Shove.

FYI,
you probably have pot odds to play against his likely calling range...even if we're never ahead and he calls with any PP and a reasonable Ax, we have around 40% equity. However, his raising range is likely much wider than that and we have some fold equity, AND he probably snaps us off occasionally with hands we dominate (KT-KJ, QJ).

You probably have the odds to do it, but you also have to take into account how the BS has been playing. If he seems to have tightened up I would fold. But if hes loosened up i would shove it all in.

i like be agressive, a re-rase ou valius bet in this situation take fair on another plays.

I play aggressive from the start but on the turn with the cards on the table unless I win probabildades

not liking the preflop shove, given the assumed calling range, but i like the shove on this flop for reasons stated by baudib.
