I usually don't do these but I'll give it a shot.

UTG+1 shows some interesting aggression on flop. If he's flopped a set, say 66 or 55, I see no reason for him to slow down after the turn. Unless, he puts you on QQ - which I suppose is possible w/your preflop aggression.

If he's playing 87d, then his flop play is pretty aggro - but given that the flop would give him an OESD and a flush draw - perhaps it is ok and might get him a free turn. UTG+1's check/calling and not check/raising the turn and not trapping UTG and hero for another bet seems consistent with 87d and not a set. Then the bet by UTG+1 on the river for the 9h (non-club) seems to suggest 87d.
