Kees Wessels, onze mathemagiër
Ook dit seizoen worden wekelijks, of eigenlijk zelfs per partij, de ELO-ratings van de huidige leden van Schaakvereniging Sliedrecht geactualiseerd. Startwaarden zijn de ratings na het seizoen 2020/2021, en meegeteld worden alle partijen uit de interne competitie alsmede alle door Sliedrechters behaalde resultaten in RSB- of KNSB-wedstrijden en officiële toernooien, zoals ONJK, ONK, Fourmies, enzovoorts.
Ook de uitslagen van de KNSB/RSB-jeugdcompetitie en kampioenschappen worden verwerkt. Ook worden de uitslagen van de jeugdcompetitie meegenomen. Zo zijn deze ratings uitgegroeid tot de meest zuivere cijfers.
De actieve clubleden en hun rating na 19 mei 2022 zijn:
