Couple off rulings in the Goliath both hands I was in
1) We get down to the river when my opponent checks, I check then he mucks without showing. Do I need to show my cards when he mucks?
2) On the turn he bets I call, the dealer pulls the money in and says "on your backs" (neither off us was all in) he then mucks the pack thinking he had dealt the river, what happens next?
