In the position above Black Rook is threaten by White knight.the question is
a)From your point of view what is the best continuation for Black?
Thanks again to Eugene for your support in solving problem 50. The key move
1.Bxh7+ (if Kxh7 2.Rxe6+ Qf5 3.Rxc6) Kh8
2.Ne4 {(if dxe4 3.Bxe4 Ndb8 4.Bxb8 Rxb8 5.Bxc6) (if Qe7 3.Neg5 Rf6 4.Bd3 Bb7) lots of continuation occur after 2.Ne4 and i just highlight only a few of them that i think the best.
