Stars $5.50...couple hands

I think I played this one fairly good. Is my flop bet a good enough size?

Should I just call here instead of pushing all in? Opponent was 52/12 over 25 hands. Not a lot of hands to make a decision on so am thinking that maybe I should have called.

Hand 1 (JJ) - that's actually a bit of a tough spot and somewhat read dependent on MP. If he's been loose/aggressive then I think this is absolutely fine. If he's the tightest player on earth I think you run into QQ+ quite often here. Readless at a $5.50 this is probably OK, you run into draws, AT and other crap that you beat often enough to go broke with an overpair.

Hand 2 (AKo) - absolutely fine, you can't call off more than 40% of your stack preflop when you only hit an A or K on the flop 1 time in 3, and you want to see all 5 cards to get full value from your AK here.

2nd hand is an insta-shove. Being on the button the blinds will reraise wider than normal. Calling and folding to non ace/king flops would be horrible
