You've seen this hand. It's the Royal Flush vs. Quads hand. However, they only showed the river action on TV, where Mabuchi bet his quads, Phillips raised and Mabuchi Splash-Shoved.
Here's how the action went down, and my analysis on the action.
From MP, Justin Phillips limps in with Kd-Jd. I guess this is an OK play with such deep stacks, but again, I would prefer a raise. Mabuchi raises from the SB with his A-A. Standard. Phillips calls. Also Standard.
Flop was Ah-Qd-9c , giving Mabuchi the nut set and Phillips a gutterball. Mabuchi checked, which is a play I am on the fence on. If you put him on a small pair (which I would put him on in this situation), then checking is right. But I wouldn't want to give a free card for KJ, JT or J8 to beat me, and frankly, all of those hands are possible, even off suit, because you're in the main event playing against a guy in a wifebeater.
Phillips checks behind looking to hit his gutterball.
Turn is a Td. Phillips makes his nut straight and has 2 of the 'pair the board' outs covered with his OESFD. Mabuchi bets, one street too late as it turns out, and Phillips just calls... If your opponent is on a flush draw or has a set, why not raise him to make him pay for his draw? If he has a set, you're getting it all in anyway, and a K or J kills your action!
River was the Ad, and you know what happened from there:

If you shove, unless he is a donk, he is not calling with a flush or straight, and might even fold an underfull if he reads the situation right.
But that's just me.
