BET THE TURN???

[hbgolfpro]

A friend of mine played this hand last night at Hollywood Park. The game is NL....$100 buy in...blinds are 2 and 3. UTG, UTG+1, MP+1, my friend holding JcTc on the button, and the BB all limp. 5 to the flop. Pot is $12

Flop is Ts 6h 5d

BB with $100 leads for $6. UTG with $150 calls. UTG and UTG+1 fold. My friend with $95 raises to $25. BB folds, UTG calls. Pot is $68.

Turn is 8s

UTG checks...my friend checks.

River is Kh

UTG bets $30 and my friend folds. UTG shows Ah8c.

I told him that in my opinion checking the turn was absolutely incorrect. First he may have the best hand, secondly he gives a free card that could beat his vulnerable one pair hand. This incorrect check then allowed UTG to successfully cause the best hand to fold. Any thoughts??? Was my suggestion to bet the turn correct??
