Knight shift

White controls all but the squares around black King . Knight will move to give more room to his Queen and depending on black response the second move becomes easy.
Three stars sound good.

Different view

mrfery moved his knight to make room for the queen. I moved my knight to protect c5, which I saw as a problem square.

Very challenging

Thanks for the puzzle. I wasn't able to see the knight sacrifice without the hint.

Quite Tricky

Clever puzzle & very well composed. I kept thinking it was the queen that needed to be moved but finally settled on the knight. It still took some careful calculation because Nb3 seems to work just fine until you try 1...Nc5, then it's obvious it must be 1.Ne6 & every response is met with mate.

Making the right move and it says wrong move.

I frequently make the correct move and it displays wrong move.Later to find out with hints that this to be true.It happens often and discourages me to do the puzzles. I do like them because it helps me have a better perspective of the options especially a sacrifice situation.

The Knight

jdh62 What if The Rook Doesn't block c5, but the knight does?

The Knight, I may have missed that.

For some reason I found this one fairly easy. As a general rule, in problems where the black king must be allowed one or more flight squares, I find it best if the squares are diagonally adjacent to the king, rather than orthogonally adjacent. I think that's because if one of the mating moves involves a knight, the knight is able to guard the flight square at the same time as attacking the king. Also two squares that are diagonally adjacent to the king cannot be adjacent to one another, restricting the king if it flees to one of those squares.

It's just a rule of thumb that I have noticed over the years, and obviously does not apply to every case.
