Russian strata: Difference between revisions

In order to induce an intended best-versus-best final, after a given number of rounds randomly drawn (e.g.: 2), future rounds will establish a stratum of players with an intended size, usually half the field. Pairings for these future rounds would be done within their stratum, with a desired pairing method (random, Siberian, or a vertical slice as examples (''note: horizontal slices would lead to the King of the hill format and do not require forming strata)). After one or two more rounds, depending on tournament size and length, the field could be divided into three or four strata. Further rounds could keep either the same number of strata, add a few, or increase to double the previous round. Aside from timing a strata division, the other thing is establishing a ranking differentiation.
