Her hand-drawn airflow maps are still consulted by archaeologists. Chess, for her, is something she keeps in her surveyor satchel and plays in the cool of the late afternoon, a few games at a time. She has watched the game for decades without ever studying it formally, and her rating of 991 reflects that: a quietly improving beginner who spots a simple tactic one move ahead but still misplaces pieces when the position grows tangled. She has no settled opening repertoire and treats each move the way she treats a draft in a tunnel, listening first, deciding second. Opponents can expect long pauses, patient looks at the whole board, and the occasional bright tactical idea followed by a slip in a messy middlegame.","65","coban","Turkey","tr","34828f8792970d76f592896a557099288d9ccd230f8d94adde445f34938a9767","2026-07-06",991,"json",[15,18,21],{"question":16,"answer":17},"What rating is Ayten?","Ayten plays at an estimated 991 Elo.
