20/180, To what degree can I assume villain is logical?

[Cornell Fiji]

I am completely new to 20/180s so I am interested from the regulars in these games about the average opponent in these games

My thoughts in white, read after you vote.

<font color="white"> Clearly a logical opponent is not pushing a queen/set/or baby flush here. This looks like someone who can't call me if he leads and I push. This also looks like someone who will not like a lot of turn cards. I don't think he is second leveling me here but how often is he betting a weak queen without a spade?
