A HU hand. Fix me.

I posted this hand in HU & Short handed section. A nice dude there said better answers here.

SNG NL $10+1
HU 100/200

Hero has been stealing pots HU from $1000 to $3190.
Tight player $4010 probably fed up with hero stealing, hasn’t change playing style yet.

Preflop:
Hero A9o BB, villain button raise $400 quickly, fed up?. Hero calls.

Flop (JA9)h
Hero have no hearts. Hero bets $600. Villain thought for a while, weakness? Villain calls. Hero put villain on Ace pair or nothing.

Turn (JA9)h 2s
Hero was still influenced by a previous hand where he folds top pair big to 4 hearts board, so hero bets 1000. Villain calls. Hero thought about quitting poker.

River (JA9)h 2s 7c
Hero checks. Villain bets $200. Hero thought for a while, light in the tunnel? Hero raise $1000. Villain push. Hero calls.

Welcome all comments.Thanks.
