I’m very new to poker and eager to learn.

Did I do anything right with this hand? What should I have done differently?

About an hour into a single entry tournament I have $43k chips (we started with $30k), 50 ante and blinds are currently 200-400 with 7 at the table.

I have pocket 8’s (spade & heart)
Everyone folds except the dealer who calls. SB folds, I make it 1,800 and villain calls

Flop: Ts Th 9s
I bet 2,100 and villain calls

Turn: Ad
I bet 2,400 and he makes it 4,800 and I call

River: 9h
I check. He goes all in for $44k, I fold.
