Board of analysis

The board of analysis is a trouble. Castle appears in two moves, promotion soesn't appear (a pawn remains in 8th rank, etc), etc.

The analysis board allows for illegal moves which opens up the door for you to speculate on future moves currently unavailable.

'What if my King were on g1 and the King's Rook on e1?'

For promotion, just select the piece out of the box below the game board and place it on the promotion square. And yes, you can put another King there.

Thanks for answers, but I think the analysis board must be another feature.
