Legit Play
Legit playing (or legit hacking) is when you use an engine in an advisory role only i.e. to give you suggestions.
To legit play using GM Cheems, go to Gameplay > Run Analysis For
and choose who you want the engine to create suggestions for.
You can also configure the engine to compute up to 5 different lines, in Gameplay > Number of lines
Each line will be shown in the sidebar, along with its score in centipawns.
When you hover over each move in the line, a preview of the chess board will pop up, so you can easily see how the moves play out.
