A team is defined as two or more players from the same school (or registered club) in the same section or in combined sections 4 & 5.
Sets are provided. Bring your clock if you have one. Clocks are required in sections 5 & 6; if neither player has a clock and all OSCO clocks are used on higher boards, the match will be declared a forfeit draw.
Tiebreaks for 1st-place individual trophies:
1. Head-to-head result | 2. blitz game | 3. Armageddon game
If there was a head-to-head match, that result is used. If not, players break tie with a G/5 blitz match. If result is not decisive, Armageddon tiebreak is used: black wins draw and white has 6 minutes vs. 5 minutes.
Computer tiebreaks are used for 2nd & 3rd place.
Complete OSCO tournament rules can be found here.
