Profile: Etan Ilfeld (knightleap)
Meet Etan Ilfeld, a National Master with a chess journey as rich and dynamic as the myriad of openings they've mastered. Etan's blitz rating has soared impressively over the years, peaking at a blistering 2282 in May 2020 — enough to make any opponent think twice before racing their clock against this swift tactician.
Known online as knightleap, Etan combines standard opening expertise with a flair for aggressive and well-studied lines. From the fiery Sicilian Defense: Open Najdorf English Attack (a personal favorite with a win rate over 56%) to the classic King’s Gambit Accepted Bonsch Osmolovsky Variation where they've racked up over 60% wins, Etan’s playstyle strikes a perfect balance between calculated precision and daring innovation.
Etan is not just about speed. Their bullet rating peaked at a commendable 2142, proving they don’t just rely on lightning-fast fingers but also razor-sharp calculation under fire. Rapid performance isn't neglected either, with a peak of 2158—showing that Etan can adapt fluidly whether under blitz, bullet, or more measured time controls.
With a career tournament record boasting over 2000 blitz wins, more than 40 bullet wins, and rapid bouts that keep even the toughest opponents on their toes, Etan has demonstrated resilience and a knack for comebacks. Their 81% comeback rate after adverse positions is nothing short of heroic, almost like a chess superhero rising just in time to save the day.
Speaking of heroes, Etan's longest winning streak stretches to 13 games—not bad for someone patiently plotting their next strategic conquest. Admittedly, the longest losing streak once reached 11 games, but hey, even chess geniuses have off days (or weeks, maybe). What sets Etan apart is the indomitable spirit not to tilt too hard, with a tilt factor of only 11, showing calmness under pressure.
Fun fact: Etan’s best hours to ply their trade aren't when the world is most awake, but at 5 am—a secret weapon time when sleepy opponents stand little chance against their tactical awareness.
