Position Analysis

White to move. This Discovered Attack puzzle comes from a Scotch Game Haxo Gambit position. With a training rating of 1322, it is classed here as Intermediate. The solution contains 3 forcing moves after the setup position.

The visible move is only half of the tactic. Here the key is opening a hidden line while creating a second threat, so the opponent cannot answer both dangers at once. Supporting motifs tagged in the source data include Interference, Mate, Mate In 2.

Training focus: Solve the line before using the reveal button. Then reset the board and explain why the first move works; recognising the motif in a real game matters more than remembering puzzle ID 0LJOD.
