The USCF is the sanctioning body for USCF rated tournaments, The NCAA is the sanctioning body for the "March-Madness" basketball championships are they relevant, damn right. Are either of those organazations necessary for their respective sport/tournaments to survive ? Of course not, what they bring to the table is a standard system in which these events are run, organized, and the process in which the eventual winners/champions are selected.
The NCAA are the biggest crooks in the free world ! OFF-TOPIC
USCF sanctioned tournaments are the REAL deal no wimps allowed !
I have learned a lot from the USCF rated events I have gone to.
