In every chess game we play, we must often ask ourselves about our opponent, "Why Did He Play That Move?" Failing to do so - or failing to answer the question accurately - can lead to disaster.
Consider the following game.
JeanTylerGabriel - LittleDonkey
Giuoco Piano Jerome Gambit Tournament
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.O-O Be6 9.Nc3 Bh3
Out of a normal (for the Jerome Gambit) opening setup, Black plays an unexpected move. Why did he play that move?
A decent enough response.
Again, why did he play that move?
11...Nf3+ 12.Kh1 Nxd4 13.Rf1 Qf3+ 14.Kg1 Qxh3 15.Bf4 Nf6 16.Rac1 Nf3+ 17.Kh1 Ng4 18.Rfd1 Nxf2 checkmate
And this is how we reached one of the positions in "Good Knight".
