Question: Am I still leading this? Am I worried about being quartering? Do I want to keep the pot smaller since I'm out of position? Or am I happy, since to get more money in with current (but no protection) nut low with a draw to nutflush?

Just never sure if its good to be pot building in this position or keeping it manageable....

Thanks.
