1) Call pre to keep ranges wider vs both this guy and the others still to act.

2) His leading range is mostly QQ/TT/99/88 and sometimes even smaller pairs, very rarely Jx (since he doesn't have many in his range preflop and he'll check often with these). Fold to his lead.

3) Cbet only folds out worse hands (AQ/KQ) and all pairs are usually calling. Check it back and take 6 free outs.
