WZ Championship games end almost two thirds of the time in draws as compared with CORR 2020 that is closer to a third of games. Correspondingly there are more white and black wins in CORR 2020 than in WZ Championship matches.
Regarding openings there is an even number between CORR 2020 and WZ Championship games in ECO A, but lower number in ECO B and C in WZ Championship games vs CORR 2020, and more games in WZ Championship games in openings classified as D an E than the comparison.
In terms of endings the profile of the WZ Championship games is very similar than the ones in CORR 2020. Only Rook vs Other Pieces and Rook and Minor Piece are somewhat higher in WZ Championship games. CORR 2020 has somewhat higher number of endgames in Pawn, Pure Rook and One Minor Piece endings.
