2.50/5 Zoom hand

[Arazi]

Hey,

I played this hand yesterday and thought it was really interesting with multiple decision points on a number of streets despite not being particularly deepstacked:

I'm UTG 4 handed with 10c 9c 9s 6s and playing $600 (the whole table covers me).
I limp, button limps, SB (good regular) pots to 25, BB folds, and we both call.

Pot $80
Flop: Ac 10s 7c

SB leads for 39, we call, button folds.

Pot €158
Turn Ac 10s 7c 2s

SB leads for pot (158), we call.

Pot $474 - we have 378 behind.
River Ac 10s 7c 2s 9d

SB checks, we?

I think I fold the turn.

As played, hard not to go broke on that river.
