With an estimated rating of 2797, he plays at international master to grandmaster strength, calculating long forcing lines with the same discipline he brings to his surgical work. His repertoire leans on classical mainline theory: with the white pieces he gravitates toward the [Italian Game](/resources/openings/italian-game) and the Ruy Lopez, while as black he meets 1.e4 e5 with the Giuoco Piano. Colleagues note that Mateusz approaches complex middlegames the way he handles complex cases, methodically, with attention to small tactical details that compound into decisive advantages. Opponents facing him should expect deep preparation, accurate defence under pressure, and a willingness to keep tension on the board until a clear strategic verdict emerges.","44","zVaFr","Poland","pl","930840f9f83639efc02a357c65497ea2065e7dbccae35609c52b4f7a2f4b25dd","2026-07-06",2797,"json",[15,18,21],{"question":16,"answer":17},"What rating is Mateusz?","Mateusz has an estimated rating of 2797, placing him at international master to grandmaster level.
