How online puzzle solving works
The position provides a side to move and a concrete goal. Study it before touching a piece. When you move, the board supplies the defensive continuation, so you can compare it with the line you calculated.
A useful solving loop
Calculate, move, review, and name the missed idea.
Read the goal and inspect the whole board.
Select checks, captures, threats, and serious quiet moves.
Calculate the strongest defense before moving.
Use the response to review the idea, not just the result.
Avoid random attempts
Repeated clicking may eventually reveal a move but does not train calculation. Commit to one reasoned candidate and study the reply.
Main rule
Use the interactive board to verify thought, not to replace it.
Open the position and calculate
Build one line before moving, then compare it with the puzzle response.
What the format provides
