Living in a rustic cottage on the outskirts of Prague, Ivan treats the board with the same patience he reserves for a slow ferment, calculating accurately and punishing inaccuracies with the precision of a seasoned brewer measuring his hops. With the white pieces he gravitates toward the classical [Italian Game](/resources/openings/italian-game), developing his bishop to its most active diagonal before steering the middlegame into positions he knows well. He carries a bottle opener as a lucky charm and favors an heirloom chessboard handed down through his family. Opponents stepping up to face Ivan should expect deep opening preparation, sharp tactical awareness, and very little forgiveness for careless club-level errors.","47","lbNzl","Czechia","cz","02c136860881a0a95605944b9cb9be41c47a256ec2bf8e854f662681a5dc2d6e","2026-07-06",2202,"json",[15,18,21],{"question":16,"answer":17},"What rating is Ivan?","Ivan plays at an estimated 2202 Elo, which corresponds to candidate master or expert level.
