I think this is fine. If we don't fill up the turn then I may be tempted to slow down but as played it's perfectly fine IMO. I think we should 4bet preflop as he seems quite active (even if only from 52 hands) so he is almost never folding preflop.
In terms of his range, I think he x/raises AA on the flop so I don't think we are behind but the flop smashes his 4bet calling range so we always have to lead here and we are going to be leading with our bluffs after 4betting pre also. Alot of the time he has A-K or A-10 or hands like 10-10 that want a cheap showdown.
Turn is a jam considering he has less than a pot size stack and he improves alot with all his Ax hands so we are getting called.
