a pot sized bet may have discouraged the first guy from making the call. He makes the right decision to fold, you dont make money when they make the right decisions, you make money when they make the wrong ones. So what if your hand doesnt hold up with 3 or 4 people seeing the river, as long as you played it correctly gave bad odds and didnt pay off the few times you are beaten then you are playing correctly and you'll make even more when you do hold up.
