I’m playing $1/$2 poker with friends. A friend had AK and I had AA on the button. I raised to $15 after a small raise before me and my friend with AK called. The other player folded. 

The flop came K, 8, 4 with no common suits. My friend checked and I bet 1/2 pot. He called. 

The next card was a 10 and I bet full pot (about $70) and he raised me all in to about $200. I called. 

The next card was meaningless and I won the pot. 

Did he play the hand well?
