Rated 3079, this bot plays at a super-grandmaster, engine-level standard, capable of punishing even strong club players for the smallest inaccuracy. As White, Duda frequently reaches for the [Indian Game mainlines](/resources/openings/indian-game-mainlines), building flexible central control before pressing an advantage. At 28 years old in bot terms, Duda's profile reflects a mature, battle-tested approach rather than youthful inconsistency. Games against this bot tend to be long, tense affairs where the position stays complicated and small edges accumulate rather than resolve quickly. Expect precise, demanding chess from the opening through the endgame, with little room for recovery once an error is made.","28","legend_jan_krzysztof_duda","Poland","pl","ff76511a6d9152545ea00273f3df1530b13e77dbb83ef3164faa9f91cce5fdbd","2026-10-05",3079,"json",[15,18,21],{"question":16,"answer":17},"What rating is Duda?","Duda carries an estimated Chessiverse rating of 3079, placing it firmly in the super-grandmaster, engine-tier bracket.
