A friend of mine played a crucial ICM hand, told me about it and we almost got into an argument. He thinks I'm a fish and I think he made a huge mistake (and that he's a fish). I'd love to hear what pros have to say on this.

Live satellite for WSOPE events. 3 players left. One of them is my friend.

1st place: 3250 ticket (decent structure)
2nd place: 1650 ticket (decent structure)
3rd place: 1100 ticket (turbo event, really shitty structure)

Stacks: 520k, 480k, 120k

Blinds: 12k/24k-3k

Button: 120k stack
SB: 480k stack, my friend
BB: 530k stack

Button folds.

SB finds 1010.

What do you do and why?

I would always push here. For ICM reasons, I don't want to get into a battle with the other big stack when the third guy has only 5 BB left. If I push my 20 BB, I put maximum pressure on the other big stack and he can only call with very few hands. He will have to fold lots of hands to my push, which would have decent equity on many flops, if he decides to defend. Even though my 1010 are of course ahead of the BB's random hand, if I raise, there will be lots of flops I won't like and I'm out of position. I'd still have to cbet but if I get called (or raised), I've got a problem, which only gets worse on the turn. So, to me this is a totally clear preflop push.

My friend says, pushing here is "total anti-poker" because my 10s are so ahead of the BB's random hand, and that I "should be willing to get it in on tons of boards".

Here's what my friend did and still believes to have been the correct play:

He raises to 52k from the SB. BB calls.

Flop 8d3d2d

SB has the 10d.

SB bets 137k.

BB pushes.

SB calls.

BB has Kd5d for the flopped flush and my friend is out in 3rd place.

Besides the general difference of opinion: If I had chosen to just raise preflop, I would have cbet much smaller and given up on the turn, if called/raised.

So, back to the original question: What's the correct play and why?
