All games will be analyzed using ICC's sophisticated anti-cheating tools. Such analysis will include, but not be limited to, comparing moves played to the recommendations of various engines. Players suspected of violating the Fair Play rules may: 1) have their results and any prize eligibility canceled, 2) be banned from future play on ICC, 3) be banned from future Continental Chess tournaments both online and over the board, and 4) be reported to the USCF Ethics Committee, leading to possible suspension of USCF membership.

Fair play checking may take as long as two weeks after the tournament. If players are disqualified, opponents who lost to them will have these results changed to half point byes and those who drew with them changed to unplayed wins. There also will be partial fair play checking during the tournament, which could result in players being expelled.

It is estimated that prizes will be mailed about August 25th.  On request, some prizes may be paid electronically through PayPal or Zelle.
