A few more fascinating tasks

Admittedly, not all chess players nor all composers are actually thrilled by task problems. But I am. Therefore, I chose three more of them for you. And I think that you may like at least some of them.

The first three compositions feature the flight task which demands that in the diagram all eight flight squares for the king that is to be mated are accessible for him. No. 1 is sort of an extension of this task as the white king is even the only piece in a 6x7 area. The second problem demonstrates the task in a minimum of two moves. It's notable that the king is mated in the middle of the board and only one flight square is occupied. Finally, No. 3 shows an ideal mate with all four bishops after a series of checks and sacs of the heavy pieces.

The task achieved in the next problems is the maximum effect of eight white promotions to a knight (diagrams 4 and 5) or a rook (diagram 6).

Composition No. 7 pleases us with an alert black king. With each key move he visits another neighbouring square. Similarly, in the last problem the black king is checkmated on each of the eight adjacent squares.
