Hello,
I think the following puzzle is flawed:
lichess.org/training/64978
The solution is 35. Bxe7 Qd4+ 36. Kh1
On move 36, Kf1 and Kh2 would be considered wrong as they only lead to a draw by perpetual check; however, if you let Stockfish 10 dig a little bit deeper, it also shows a draw after 36. Kh1 g5! -- the computer did not realise that in the quick game analysis that the puzzle is taken from.
