I have to take a closer look at this code.
For now, the moderator of our forum started a topic about the blindfold trainer :

(he's a rather good but non-active chess player)
A quick translation (don't shoot at the messenger
- moves without the 'check' or 'mate' notations should be accepted as correct
- the question about white: Kh5 Lb1 Pd7 g6 h6 black: Kh8 Ta8 a7 b6 claims g7 mate (which seems not to be the case)
- some positions made giving checkmate with more than 1 piece possible, only one move will be accepted by the app.
- maybe too many questions about knight-moves and diagonals
