His bullet and blitz performances show steady competitiveness, with peak ratings of 791 and 931 respectively—respectable marks on the battlefield of fast-paced chess.
Yet, Kacper is not just about numbers. His recent games show a resilient performer—winning by resignation with precise play in a Philidor Defense, yet also humbly accepting losses, learning from tough battles like those against specialists in the Caro-Kann Defense. His longest winning streak stands at nine games, while the learning curve momentarily hit a harsh slope with a 10-game losing streak, proving that even chess heroes have their humbling moments.
Off the board, Kacper has a Tilt Factor of 10, deftly balancing competitive fire with a cool head. Armed with quick resignations in only about 3% of his games, he fights hard until the end, proving that when it comes to playing chess, giving up early is simply not in his vocabulary.
