He still has a little over 50BB left behind. and only risked about 8 so far.
Now the question is.
Would he overbet shove with a K or A made flush? Why not just reraise? The only reason to reraise is if you don't put your opponent on a flush draw. since you will likely chase them out of the pot. And your basicaly helping them get all the money in while they think they're still ahead with their 2pair/set/etc. So it doesn't make sense for him to overbet shove there.. unless he put Mike on a set which he thinks he will laydown since he's horribly behind against a set.
I like Mike's reraise. but i'm not too sure about folding.. it's for his tournament life, he still has plenty chips left behind. Johnson actualy has a 28.8% to win (according to pokerstove + other calculator) So that does change it a bit imo. vs a set he's a 2 to 1 favorite. he basicaly crushes all other hands badly. exept ofcourse a made K/A flush.
Taking all that into account:
I just dont see a hand he could put Mike on that he'd be overbet shoving the flop with for value. He's behind against 2pair, sets and made flushes. If he tries to make mike fold 2pair, sets and maybe some bluffs why not just make a normal big reraise which imo looks stronger. Unless he assumed Mike would fold a made flush but that's very unlikely.
So i personally hate the other guy's all in shove. Mike's fold.. i wouldn't lay it down personally.. he's basically a 2 to 1 or bigger favorite exept again higher made flushes.. and considering it's unlikely he'd shove all in there with an A/K flush since there isn't any reason to do so with. And even more unlikely he actualy has that. i think calling is really alot better then folding.
Not sure why i wrote so much.. I was actually going to defend Mike a little to let you guys see it from a different perspective. But after really thinking about i think folding is pretty bad here. However if the guy had the AK of spades i think the comments would have been alot different. then you'd probably see "yeah very good laydown. But it was vs tightest player of the table. so i could see the reason why he did". or the standard "easy laydown".
