I don´t know who is in charge for Tactics trainer and I can´t find any useful info so I post here.
It would be nice to have a report problem button on tactics trainer.
For example: In problem 0042965 the solution is to move a rook on second move instead of Ng4. Please explain or fix.
Ng4 loses your Queen.
Thank you. So in order to win faster, you move the rook. Aha.
Not sure what you mean ?
Your suggestion of Ng4 will lose you a Q and a rook and no forced checkmate. The suggested answer of RxN is the correct one.
