Xiangqi Blunder Checker
Use AI analysis to find missed tactics, blunders, and turning points, then understand why a move made the position worse.
A blunder checker should not merely say that a move was bad. It should show where the mistake happened, why it happened, and how to avoid the same pattern later. The most important nodes are usually where the score changes sharply, a threat appears, or an advantage disappears.
Load the full history or a FEN with moves so the page can replay the position before and after each move.
Watch where the engine score changes the most and mark those nodes for priority review.
Compare the played move with engine candidates and decide whether the mistake came from tactics, structure, or tempo.
Save the conclusion as an error label such as missed check, greedy capture, weak king, or slow transition.
