My opinion
Ken Schuman didn't make the ruling in Darren's match. Ken made the call Monday night against Shane and called it a loss of game. The call between Darren and Jason was made by Bill; Ken was not even in the room so it is unfair to call him shady without even being there and knowing the situation.
In the bank final he called it exactly as it should have been.
This was my 10th year at DCC, playing the bank event. Not knowing exactly what happened, or how many balls are moved, makes this tricky. Look at the one pocket rules, as they are posted on the website. I do know, when I played the one pocket and banks a few years ago, that IF your opponent moves the moves the balls, thinking you are out, the game is over. If you move multiple balls, thinking the game is over, I believe it is like conceding the game. That's my personal opinion. As for the other call, on Darrens match, it could be that only 2 balls were moved, as suggested, or the guy who made the call, didn't know.
As for fairness at the the Derby, and Ken Shuman's direction,,,, this is also, my opinion. I was scheduled to play a well known one pocket player at the Executive West several years ago in one pocket at 10am, when Scott Smith was running the DCC. After they had the draw posted, they said they were changing the morning start times to 11am. That was fine. At 11, I was at my table hitting some balls and waiting. 11:15 a friend comes up and asked if we started yet, I realized the time and went to the front desk. They refused to put him on the clock, and he finally shows at 11:45. In Scott Smiths defense, he wasn't at the desk, but this should never happen to anyone.
This year, I was waiting on a TOP rated Pro for a bank match scheduled at 10am. At 5 after, I went to the desk, and had them page him, and they put him on the clock. At 11:16 they forfeited him. Mr. Shuman was right there, and did exactly what he should have. There will always be some conflict with the rules, when you have several people making calls. But, overall, the DCC is a very well ran event, or it wouldn't have had a 14 year run. Greg and his staff do a great job in dealing with a large number of players, and some really tough personalities.
