Both villains is unknown, 6 hands. SB seems like a donk because of stack size and 33/0 stats.

c-bet flop, or is this a fine plan? (was going to bet the turn as played, if it wasn't for the bet from BB)

it'd just cbet, charges draws, could get called by smaller pairs as well

on the river you only beat a7 out of hands that call and maybe crying calls from pp , better to bet earlier - as said above cbet to charge draws - even though multiway pot you have position

Im not giving any free cards on that flop, Im Cbetting that almost 100% of the time

As played I like the call OTT, but I'm checking back that river since all you will never get value from a worse hand and never get a better hand to fold, so there is no reason to bet
