FeynmanMAC64: The Bullet Tinkerer
FeynmanMAC64 is a bullet chess enthusiast who plays with the curiosity of a physicist and the stamina of a marathon runner. Across roughly 1,800 analyzed games, this player has built a reputation as a high volume, 1.e4 fighter who is equally willing to defend sharp Sicilian lines and to play offbeat gambits. FeynmanMAC64's preferred time control is bullet, and the numbers show why: the player's bullet form improved dramatically during 2026, climbing from a tough 1686 start to a peak of 2513 (2026-09-14) and also reaching 2422 (2026-07-01) in blitz.
Playing Style
FeynmanMAC64 plays quick, ambitious chess. The record shows a 50.3 percent strength adjusted win rate in bullet, a near 90 percent comeback rate, and a 43 percent win rate even after losing a piece. Games tend to go deep, with wins averaging about 79 moves and losses around 66 moves, and rook checks are a favorite tool. The longest winning streak reached 10 games, though the longest losing streak stretched to 12, a sign that the same aggressive engine can overheat.
