Thanks for pointing this out—that’s a great observation.

You’re absolutely right that in modern practice, especially with quieter setups like d3 and c3, the traditional distinction between 3...Bc5 (Giuoco Piano) and 3...Nf6 (Two Knights) often becomes blurred due to transpositions. As your example shows, both move orders can reach the exact same position, so the difference is more about move order than the resulting structure.

My intention was to highlight the classical classification and the typical ideas associated with each, but in practical play—particularly at higher levels—they frequently converge into similar middlegame setups.

Really appreciate you bringing this up @tpr said ^
