Hand from 20nl hu cash. The player is reasonable enough. But he doesn't normally raise top pair. I call the flop bet, to let him barrel. Turn isn't ideal but i'm still not 2 worried.
On the river, say villain checked, would you bet small for value or just jam? I think I prob bet small 2 get some value from villain.
I have

OTB (£20 stack )
Villian has £16 behind. I min raise to 40p (my standard open) HU cash to people normally 3x pre? I'm so used to playing HU sit and gos.
Flop,

Villian checks, I bet £1.40, he check raises to £2.10. I call, pot is now £5.
Pretty confident I have the best hand here, I just call to let him barrel. Quite happy with this, if I raise, i'm folding out so many of his weak hands. He could have slow played something like Jacks or 10s.
Turn is the

, not brilliant but still quite happy. He doesn't usually check raise top pair, mybe he would with K9 Ace 9, but that's such a narrow part of his range, so i'm not 2 worried.
He leads for £3.75 (3/4 pot) I call, pot is £12.50. I have about £13 behind he has £9 behind.
River is

, he jams I call.
Thoughts on my line in the hand? If villain checks the river, i don't think i jam cause he's struggling to call, might bet something really small like £4/£4.50
Edit, i could fold (turn??) river, don't know if this would be good or bad, i'm happy that opponent doesn't have a 9 here often enough to call.
