Damiano Defence
Hunt the exposed king
The attacking idea
Use queen and bishop checks to pull the king away from its defenders.
The temptation
Taking the knight opens the diagonal to h5 and exposes the king.
If they defend
Use Qe7 to meet the threat instead of taking the knight. White still has pressure.
Look for the tactic as you develop. The opponent can choose a different route.
