Ponziani Opening
A checking bishop reaches the rook
The attacking idea
Use Bb5+ and central exchanges to open the diagonal toward the rook on a8.
The temptation
The d6 push attacks the knight but allows a bishop check before the rook is safe.
If they defend
Move the knight to g6 and exchange the advanced knight before challenging the centre.
Look for the tactic as you develop. The opponent can choose a different route.
