AK hand. What's the best play?

[reallybigshoe]

Party NL $25 table. I'm in CO with AK of hearts. MP2 min. raises, I reraise to $3. Button calls, as well as SB and BB. MP2 calls.
Both blinds were huge stacks at the table, relatively speaking, so I felt like the Button priced them for a call and they wanted to gamble. The Button was really loose, seeing a lot of flops. No read on MP2.

Pot is $15 roughly. I have about $19 in my stack. I make up my mind that on a good flop with a potential draw I push, as a value bet is going to cost me over half my stack anyway.

Flop comes K-7-2, two hearts.

I got what I wanted, it's checked to me and I push. Button reraises himself all-in.

Does anybody play this differently? Is this more of a tourney move than a ring game?

I'll post results after some comments.

Thanks in advance.
