In ring games I always am one of the first guys to look at my cards. So if they ask me to chop and my hand isnt very good for HU, I'll accept. But if its good HU, I wont chop with them and I'll put a raise in. Some poor players at the table comment on how its self-serving, and it completely is. But I play for myself, not my opponents. If they are at sitting at my table, and I have the opportunity to win their chips, im taking it.
