The caliber of players is unusually high at a 186 tournament
That is because the stakes are unusually high.
While trophies look good on the mantlepiece, to a player, (and dusty to his or her heirs,) the reality is that proffesional players, by neccessity, run on cash.
A win at the Internationals may support the pursuit of a 186 payoff, but not for long. A win at a 186 will
support repeated attempts to dress up the living room.
