In the first hand I'd assume jacks thru sevens before I'd put him on A3/K3. The flop plays looks like trips with a terrible pf cold call but I could see an agg. capping the flop with said pairs. I'd lead the turn and see what he does. If he reraises then I'd lean towards trips, but a check invites a continuation of his flop-cap which doesn't narrow his hand range really. I'd be tempted to call down even if he reraises the turn.

On the second hand I'd probably call the river, he didn't hit a set of kings, looks like AK, but could've been Aces with his river bet, I'd call the river.
