I normally don't C/R the river heads-up, but ...

... this kid was showing too much aggression to resist. Besides, the little twit deserved it when you see what he raised the flop with.

Don't be angry cause he raised you on the flop. Apparently he thought - I can scare the crap out of this guy with his AK and see the river for 1 SB. He was right.

You should 3-bet the flop.

Reraise the flop. What do you put him on? He didn't even raise preflop.
