hand #1 (yeah, bad call for 10x BB with AJ - anyway) you hit your Ace but you check and call...??? You need to lead out here or at least be check raising (I love how players raise 10x BB with A8 - wow) You hit exactly what you wanted on the flop and you need to bet or get out there and now if he has AQ or AK (or 2 pair)

Hand 2 I cold call the raise there - Obviously players are raising with A8 so there overvaluing hands big time - I also like that you raised his flop bet...He then checked and called down - He was probably scared you had a 10 and was looking for a cheap showdown (bad players LOVE to show that their aces got cracked like it's a million to one shot) - I have no problem with the way you played that...You let a weaker hand call you down and didn't risk much when you were beaten - Only thing where you might just fold that flop is that you said he was TAGgy...that player you have to give more respect to, but again, at these levels players c-bet that flop with AQ also, so JJ might be good a lot there...I check/check the river also there - He just happened to have aces - I think you played it well though -
