What does "best five out of eight" mean? The following dialogue is between two chess players at the end of a game. Does it mean &quot;you have lost 4 games so far, what is your idea about going for the 5th game and developing the competition to 8 games&quot;?
Dialogue:

A: Checkmate! Care to try for best five out of eight?
B: No, Thank you.

To me, it just seems A is asking for a match of 8 games. If you exclude the possibility of draws, you'll need 5 wins to win such a match. This is similar to the best-of-X formats used in playoffs in many sports.

In any case, it's not terminology specific to chess. You might have more luck on English Language &amp; Usage or English Language Learners.
