CU is 33/33 after 3 hands no read
D is 16/9 after 133 hands / 2% 3 bet pf

i posted a similar topic about being raise small on river and when its hard for villain to have many bluffs in his range. im never really sure what to do when facing small raise on river

so i decide to call pf because of odds.

should i lead on flop?

as played

when facing small raise like this on river, should i fold or call? i have 2 pair which is very strong but its really hard to say if he only to this with Kx or a busted FD or SD
