Hint
Home – Hint (you can also press F2)
“Hint” brings up a special window with extensive advice on the current position.
You can click buttons to find out which enemy pieces are attacking your pieces, which of your pieces are under attack, and which are undefended.
The engine's “plan” shows you the threat you are facing from the opponent, and “Suggestion” gives a constructive suggestion on what you should play next.
The quality of the hint assistance depends on the search depth, which you can adjust in the “Game” options.
