How answers improve puzzle training
A correct answer confirms more than the first move when you have already calculated the likely defense and continuation.
A wrong answer is useful when you locate the exact branch you missed instead of immediately replacing it with the displayed move.
Use the solution in four steps
Delay the answer until you have a concrete line.
Scan the position and choose candidate moves.
Calculate the best defense to each serious candidate.
Play the move only when your line is complete.
Compare the response with your calculation and repeat the corrected line.
What to check after the answer
Look for a missed defender, an illegal assumption, a stronger forcing move, or a quiet continuation that your first line ignored.
Main rule
The answer should explain your calculation gap, not replace the attempt.
Test a line and check it
Calculate the position, make your move, and use the answer to review the critical branch.
Why immediate feedback helps
It connects a concrete decision with its consequence while the original calculation is still easy to recall.
