<font color="#CC3333">Hero bets</font>, <font color="#666666">1 folds</font>, <font color="#CC3333">Button raises</font>, Hero ??

He could have an ace or a Q with a better kicker so I call . For the river I'm going for a check/call because if I bet and get raised there a big chance he has a Q with a better kicker (theres 8 over and just 4 under to mine).

Thoughts?
