Kopp's Big Hand With Moon

[Zybomb]

In case you didn't see it I'll recap. Play is 12 handed, 2 6 handed tables. Payouts for 10-12th are identical.

To the best of my knowledge Kopp has roughly 20 Million and Moon has roughly 25 Million. The avg is about 11 Mill. Both are top 4 stacks. Moon (from TV only) seems to be playing fairly abc but has been dealt a lot of hands,

Kopp opens the 120k/240k blinds with 53 to 600k . Moon calls out of the SB

Flop: K92

Moon Checks, Kopp bets 750k into a 1.6 Mill. Moon calls

Turn: 2

Moon checks, Kopp bets just over 2 Million. Moon check raises to 6 Million. Kopp shoves for almost 19 total

Over playing his hand? Played Correctly? How would you play different?
