Rated at an estimated 3325 Elo, Jerry plays at super-grandmaster strength, calculating with the precision of an engine and converting small edges into clean checkmates. As Black against 1.d4, he favours the energetic [Budapest Gambit](/resources/openings/budapest-gambit), and against 1.e4 he leans on the resilient [Classical Caro-Kann](/resources/openings/classical-caro-kann), bringing 92 and 32 logged games respectively to those lines. His repertoire blends mainline theory with subtle, solid choices, reflecting a player who knows when to keep tension and when to release it. Opponents facing Jerry should expect near-flawless technique, deep preparation, and an opponent who punishes inaccuracies without mercy.","52","XTtSv","England","gb-eng","9400c3e95a4ecfae133454a3af063b7a70118770ba17d93e5d0cac91dadb15b8","2026-07-06",3325,"json",[15,18,21],{"question":16,"answer":17},"What rating is Jerry?","Jerry is rated at an estimated 3325 Elo, placing him firmly in super-grandmaster, engine-tier territory.
