AK no good

I ran AK into JJ to bust out in my last three tournaments. One the guy had it utg and limped. I raised happy to take down the pot of 5 limpers and he pushes all in. He was the big stack. Gotta think the limp push move from utg with JJ is not the greatest strategy,

The other tournament I played I was in the bb with 77. Folds around to the button who makes the standard pot size stealing bet to 210. I have 1700 behind and I push. He does not even think about it and calls for over half his stack. He had Ah3h. Insta call, really? Of course the ace is the first card out and igh. Something has gotta hold sometime. Right?

Addendum: AK just beat AJ. Was worried. You know because of the jack and all.
