Please read CCC Terms and Conditions and Fair Play Policy.

ALTO is only open to players age 21+ as of October 26, 2025.

Spectators are not permitted in the playing area or in the nearby hallway.

Registration Cap: 140 players.

100-Point Rule: Players may play up if their rating is within 100 points of the section limit. Example: 1800+ to enter Championship. In addition to October US Chess supplement ratings, we will also honor peak ratings since August 20.

Ratings:

• All sections are US Chess-rated.  US Chess membership is required.

• Championship and U1800 sections are also FIDE-rated and use FIDE rules.

• No minimum rating to enter.

• Unrated players must enter the U1400 section are are eligible for place prizes (1st-3rd) in that section.

• Ratings Used for Pairings and Prizes:

  • For most players, October 2025 US Chess supplement ratings are used.

  • For players who would otherwise be unrated, their live US Chess tournament history rating will be used.

  • For players who are “playing up” based on their most recent live (tournament history) rating and using the 100-point rule, this live rating will be used if they would otherwise not qualify for the higher section.

  • For players who are “playing up” based on a peak rating since August 20, but who have since fallen below the 100-point cutoff, they are still eligible for the higher section, but the highest of their August supplement and most recent live rating will be used (not necessarily the peak rating).

  • For foreign FIDE-rated players with no US Chess rating (or insufficient recent US Chess rating history), the following formulas may be used to assign a US Chess rating:

    • FIDE Ratings 2000+: 1.02 * FIDE + 20.

    • FIDE Ratings U2000: usually assigned at par, unless a different foreign rating system (e.g. CFC) is available and used for rating assignment, with possible adjustment by the Chief TD.

  • In exceptional cases, the Chief TD may assign a different rating than specified above to a player for any reason. Assigned ratings will never be lower than the current US Chess supplement used for the event.

Byes: 

• Any changes (registration, byes, withdrawals) must be submitted at least 1 hour before the round in question.

• Half-point byes allow a player to skip a round they cannot otherwise attend.

• Players may take up to 3 optional half-point byes, request before round 1.

• All byes requested during the tournament are zero points.  Half-point byes must be requested before round 1.

Refunds – all withdrawals by October 22 will be refunded minus a $10 transaction fee. 50% withdrawals after October 22 until 1 hour before round 1. No refunds after.

In all sections, White's clock will be started at the start of the round, even if players are not present.
