Exactly this. I just watched the complete Shane v Alcano match again,it was obvious to a blind man on a galloping horse where Shane was going with the 10 ball, and having Uncle Fester as a ref didn't help.Some people sell there integrity very cheaply.
Originally I thought the same thing but having seen the same ref let it slide in other matches and only enforce it when the opponent said something, I put the blame squarely on the tournament director who allowed non-standard rules to be used and to a lesser extent Alcano and Paopao.
Having said that most Americans have no idea what poverty in the P I is like. If I was living in that dog eat dog environment I may have done the same thing as Alcano and Papao.
