thank you so much
You're welcome.
I need help Rule 16
white to move
Qb5+ is the solution. Because after axb5 (only move for black) axb5 by white is mate.
i need help
This is a nice one. The solution is the crazy looking move Nxd7+ , sacrificing the queen. Black now has a lot of moves, though all lead to mate in one for white. So let's say black plays Nxe2 , then Nf6 (double check!) is mate.
another one, pls help
Qh7+ is the solution here. If Kxf6 then Ne4 is mate. If Kf8 then Qg8 is also mate.
thank you so much
