Tom, as the TD of Hard Times, I am sure you have seen your share of savers! I would venture to guess that Marlon Malano and Jose Parica may have considered a saver at your recent 9-ball event because of their Philippino bond.
Quite often, especially between two friends, before a match begins, the two players will agree to a percentage of their winnings to go to the loser of the match. Generally, in my experience of what I have seen and heard through the grapevine, it is a small percentage, 5 or 10 percent. However, each player is trying to advance the chart and capture the almighty win. This is a generally accepted practice which occurs with Pool Super Stars, UPA admin staff, Hall of Famers, U.S. Open winners, and the average Joe, especially on the road between two friends, but it is still a fight to the finish.
Now, having said that, if players are deliberately losing a match because of Calcutta monies, this is not a generally accepted practice.
As long as the two players are trying to win with all their might, I see nothing wrong with a saver. It is only a little jelly roll, a gift of friendship, if you will, between comrades. So, in my opinion, whether a saver is public knowledge or not, as long as there is no intentional losing involved, it is okay by me.
Some players are good for their word and pay off the saver at the conclusion of a tournament, and there are others who procrastinate, sometimes leave town without paying, and do not honor the gentlemen's agreement of a saver. People do get funny when they're winning that big money, and the key to avoiding this kind of happening is to not save with anyone.
JMHO, FWIW!
