In the Four Knights Game: Spanish Variation, Rubinstein Variation Accepted, indigonl defeated Shah9903 with a final accuracy of 85% to 73%. The game began with a relatively even exchange of moves until 7. d3, a move that significantly shifted the evaluation in Black's favor, with the engine suggesting 7. Ng3 as a better alternative. Black capitalized on this opportunity, although they missed a chance to further press their advantage with 13. g5, where 13. Bxf4 would have maintained a strong position. White then made another critical error with 14. Nd5, allowing Black to equalize the material. However, Black blundered on move 16 with 16. Be7, allowing White to gain a decisive advantage. White continued to press, and despite a mistake on move 20 with 20. a4, Black's final blunder on move 21 with 21. Qxd3 led to a forced mate. White delivered checkmate on move 26.
