PLO25 zoom just give up?

Hi

only 13 hands on the opponent: 62/8, so I don't know anything about him

Usually is not worthy to try to make people fold a Q or over pair on this spot, that's why I don't bet turn even with my pair + GS, but on the river, probably is different, because maybe he could fold a bare Q or KK and AA to a big bet, would you try this? his check on the turn means he is weak but with SD value most of the time in my opinion, what do you think about this? The problem here is that I don't even represent 56, but who knows

Thanks!
