BB special against 5 limpers

[RockyMoose]

I flop the second nuts early in the tourney, no reads on anyone. Was my leading flop bet correct? (I think so: overbet the pot to give bad odds to any draws.)

Better question: Was the guy with the open-ended straight-flush draw correct to call for all his chips behind two shoves? I'm thinking his call was ok: he had the ass-end of the straight already, which was not as good as he thought it was since I already had a higher straight.

Last question: the button shoved over with an open-ended straight draw. This seems donkish to me, especially after I showed strength on the flop and another player called. He was a donk, right? I can't see how his move made any sense at all.

(I assume my call/shove was correct. I'm only losing to exactly T9.)

Well the button's reraise is probably ok, since his range for you probably includes some sets and 2-pair hands. He's obvious a favourite against those. It's pretty marginal though (I think). On that board, the CO calling 2 all-ins wih an OESD is just idiotic. He's obviously not thinking beyond the strength of his own hand.

Potting the flop is fine, and calling the AI bet looks fine to me.

Naka, I think you got Button and CO mixed up here:
- CO flopped the ass end straight and has an OESFD. If I was in his spot I'd be raising the flop (600 to go) rather than just flat calling. As played, I'd definitely call two AIs with what he has.
- Button should give up on the flop with his OESD and overcard with the bet and call in front of him. He doesn't have odds to chase - because of the 2-flush on board he doesn't have 8 clean OESD outs and his overcard may not be good either. I think his shove is bad indeed.

Hero obviously played fine at all points.
