Pre-flop: ($1.50, 8 players) Hero is BB
1 fold, MiDra666 calls $1, CH4PSTER calls $1, 2 folds, helga99 calls $1, Rugoom calls $0.50, Hero raises to $6, MiDra666 folds, CH4PSTER folds, helga99 calls $5, Rugoom calls $5

Flop: ($20, 3 players)
Rugoom checks, Hero bets $16, helga99 folds, Rugoom raises to $38, $22 to Hero ($78)?

Having some trouble with his limp/call range. I suppose SCs are in his range given he may have felt priced in by helga's call. Does villain do this with pair+draw? weaker overpairs?
