On the board he plays at an estimated 2449 Elo, placing him in the national master to FIDE master range, a level reached through decades of disciplined study rather than weekend hobby play. With the white pieces he favors direct central breaks, most often steering games into the [Scotch Game](/resources/openings/scotch-game), and against 1.e4 c5 he heads straight into the [Open Sicilian](/resources/openings/open-sicilian). With black against 1.d4 he relies on the counterattacking [Grünfeld](/resources/openings/grunfeld). Opponents should expect precise calculation, almost no blundered material, and an opponent who will punish loose moves the way a missing keystone collapses an arch.","33","lYhJT","England","gb-eng","05d4ab0962c92deea95027d987d450ada9ff5b4078836d8f470bd2cd242db1fe","2026-07-06",2449,"json",[15,18,21],{"question":16,"answer":17},"What rating is Ethan?","Ethan plays at an estimated 2449 Elo, which sits in the national master to FIDE master range.
