With an estimated rating of 2942, she operates at international master to grandmaster strength, calculating long forcing lines with the patience of someone accustomed to inspecting inclusions under a loupe. Her white repertoire favors quiet, structural setups, frequently steering games into the [Colle System](/resources/openings/colle-system), where small positional advantages accumulate over many moves. Against 1.e4 she relies on the Caro-Kann complex, while her occasional dabble in gambit play surfaces in sharper white tries. Opponents can expect a slow squeeze in closed positions, accurate defense under pressure, and ruthless conversion once an endgame edge appears on the board.","40","VGYSr","United States","us","9437c3799896abfd3fc684022fb703fcfe6bf9ebfdaf1483d53c3d73a53e5737","2026-07-06",2942,"json",[15,18,21],{"question":16,"answer":17},"What rating is Tiffy?","Tiffy plays at an estimated 2942 Elo, placing her in the international master to grandmaster range.
