Swiss is a type of tournament that consists of a number of “stanzas”. The contestants are assigned start positions between stanzas.
You must click the Swiss tickbox in Game settings to indicate that BTC shall not end the game at the end of the stanza. BTC will alert you if it suspects that you are about to start a Swiss.
Before the last stanza you should remember to untick Swiss, but there will be no disaster would you forget.
See the Manual for more detailed explanation of Swiss games.
TIMER The timer will start each new stanza from scratch.
