Well, the idea is that Bxc3 is mate. However, that is not playable at the moment as the bishop is pinned to the king because of the queen. That is why the knight on h5 is free to take, because if the queen recaptures Bxc3 is checkmate. So the motif here is "Removal of protection", because the queen cannot leave the g-file without allowing the bishop to move.

Thank you for your answer. I understand the task very well. I try to understand how to go through the book. When you look at white so it is an obvious knight fork. How can I know that I should not look for knight fork in the task when black in move. If you know what I mean. When white in move so it is a typical knight fork and this is not "removal of protection"...

If the chapter has both topics, you will just have to check them both. Also, you should really try to understand the position and come to the best possible conclusion without already looking for a specific motif, as that could hinder your learning process. It that sense it might be better if white to play and black to play constitute different motifs, as it forces you to consider more.
Hi. I adress this topic to the ppl that own chess book Combinational Motifs M.Blokh. But ppl that do not have this one can helpe me too!
There is a main chapter 1.1 Knight forks and there is another 1.1.1 Removal of protection.
There is a chess diagram nr 2 in the book. The picture below.
Black in move. The correct move is 1 ...Qxh5 2.Qxh5 Bxc3#
What is the connection with the Knight fork in the topic????
White in move: 1.Qxg7 Nxg7 2.Knf6+ Kf7 3.Nxd5 --- The knight fork is obvious here.
Can you explain me the black move and what is the connection with the topic "Knight fork"? I have a liitle problem to go through the book when I do not know what to look for (It is a learning process).
