Hand 1 I think you played a little too passively. A check raise to the agro OP could have set you up to either open bet the turn a little higher, or if you had a feeling he might bet again, another check raise which probably would have won you the hand with a lot more value. I’ll give you a B- on this hand.
The second hand, you played quite brilliantly, IMHO. Too many poker players, even experienced ones, get married to AA way to easily. Your check call on the turn is good, and your call on the made flush was understandable as well. The fact you flat called when you hit what many would consider the nut flush, which obviously was not, is what separates net losing players from those with +EV. you get an A, and a lollipop for extra credit!
Fun stuff man, thanks for sharing.
