Chess in 40 SecondsStop the Fried Liver
Black to move. Don't take back: hit the bishop.
Snort took on d5 and is eyeing f7. Don't take back — chase his bishop.
Hint
Make the bishop leave, and f7 is safe.
Answer
Na5 — Correct! Na5 chases the bishop and the f7 attack never comes.
The tempting mistake
Taking back on d5 is exactly the Fried Liver: his knight crashes into f7.
The idea
When f7 is under attack, chase the attacker away instead of grabbing material.
