/********* Find games with the longest sequence of consecutive forced moves that are actually made This is a rare case where the version 6.1 version is clearer. We cannot use ⊢ {countmoves legal -- == 1} + because the repetition signal '+' only applies to the right-most preceding dash constituent, and here there are none. Likewise, ⊢ {countmoves legal ―― == 1} ―― + would fail because the trailing '+' would only apply to the ―― . That is why we enclose the filter and dash inside a chain. -- *********/ cql(input hhdbvi.pgn) sort "most forced moves" ⊢ ({countmoves legal ―― == 1} ―― ){3,}
