maybe pushed a little harder preflop JJ is very good heads up but still dangerous to let hands like Ax Kx in. I dont know why so hard of a push on the turn although you have a good hand with above middle pair hes playing like he has a K and top pair heads up is usually ok to play to the end with especially with a good kicker. Doesnt matter either way because once the river came you both would have moved all-in anywayz.
