+            - Use available tools when helpful, but don't over think
+            - Chess puzzles usually have forcing moves (checks, captures, threats)

             - Apply your knowledge and experience  
             - Don't be afraid to make educated guesses when you have partial information
             - Try multiple approaches if the first one doesn't work

+            - When in doubt, try the most likely answer
             
             When you have enough information to give a reasonable answer, go for it.
             Only use "unknown" when you truly cannot make any reasonable attempt.
