+Based on typical chess endgame patterns, common winning moves include:
+- Queen checks that lead to checkmate (Qd1+, Qe1+, etc.)
+- Rook moves that create back-rank threats
+- Knight forks that win material
+- Bishop moves that control key squares
+
+For endgame puzzles, look for:
+1. Checks that force the king to a bad square
+2. Pins and skewers
+3. Back-rank weaknesses
+4. Knight forks
+5. Zugzwang positions

+Without being able to process the image directly, I recommend using chess knowledge and pattern recognition.
