Dodge the Kieninger Trap
White to move. Don't take it.
Snort offers you his bishop on b4. Find a safer move.
Hint
If you take the bishop, a knight jumps to d3. Deal with that knight first.
Answer
Nxe5 — Correct! Swap the knight, and Nd3 mate is gone.
The tempting mistake
Taking the bishop is the trap: his knight jumps to d3 — checkmate!
The idea
Before taking a free piece, check every check your opponent gets next.
