White to move — find the best continuation

Solution & explanation

Main line

11. Na7+ Kd7 12. Bc6+ bxc6 13. Qxc6#

Why it works

  • Great move! knight to a7 keeps the pressure (#2).
  • Spot on — bishop to c6 (#1).
  • Strong! queen to c6 is the sharp choice (#).
  • The line ends in a forced mate in 3.
  • If instead Kd7, then Bc6+ and you stay on top.
