Antoni Kozak - National Master & Chess Dynamo

Meet Antoni Kozak, a National Master whose blitz and bullet ratings fly so fast they might just break the sound barrier. With a peak blitz rating soaring above 3000 in 2024 and a bullet max flirting with 2988, Antoni’s opponents might need a jetpack to keep up!

Antoni’s chess journey is a marathon of intense battles and epic comebacks, boasting a 92.37% comeback rate — yes, you read that right, nearly every time it looks bleak, Antoni flips the script like a grandmaster magician. They even hold a record-winning streak of 53 games, proving that when Antoni’s on fire, resistance is futile.

Their style? A blend of patience and tactical wizardry characterized by an average of 86 moves per win — slow and steady, but deadly precise. Despite an early resignation rate under 1%, Antoni knows how to keep opponents guessing until the very endgame, which comes up a whopping 84.72% of the time.

Interestingly, Antoni’s black pieces win at a solid 51.51% rate, while playing white is even more productive at nearly 56% wins — maybe they have a secret handshake with the pawns? Beyond ratings, Antoni’s psychological resilience and top-notch tactical awareness make losing a piece just a temporary hiccup — they bounce back and win 100% of those time! Talk about turning lemons into checkmate.
