Solution move by move

1. 1. Red -R=4 (captures the Soldier, sacrifices the Chariot)

   Why it works

   • Wins material: takes the Soldier.

   What to watch out for

   • Gives up the Chariot; the follow-up must be exact or the sacrifice is wasted.
   • Not forcing: the defender has 13 replies, so compare each one before playing it.

   1. Black R7=6 (captures the Chariot)

2. 2. Red R7=3 (threatens mate next move)

   Why it works

   • Creates an immediate mating threat that must be answered.

   2. Black K5=6
