That's correct. Congrats for finding the solution first! :)

Interesting is that 2. Bc8? doesn't work because of 2. ... Bxc3 3. Td5 Be5+. White has to force the black knight to block the square e5 first ...

I will add the complete solution with all important side variations now.

Exactly, I was trying 2.Bc8 first as you said but the black bishop checks the king and the solution was not in five moves, so I found 2. Be6 to bring the knight on g6 to e5 square.

Thanks :)
