AI Chess Teacher / Blunder Spotter
Tactical alarm-bell training · Real game positions · All levels
Most chess games at amateur level are decided not by brilliant moves but by blunders. Learning to recognise the kinds of moves that lose material before you play them is the single best return on study time below 2000 rating.
Blunder Spotter shows you a position with a candidate move and asks: is this safe? Train your alarm bells to fire on the patterns that cause most losses — hanging pieces, undefended back ranks, knight forks one move away — and your practical results improve immediately, regardless of your opening or endgame knowledge.
