1.d4 a6 2.e4 d6 3.Bc4 a5 4.Qf3 {I figured that I might as well give this a shot and see what it was that Harrison was doing. (R.C)} f6 5.a4 e6 6.Ne2 c6 7.Nf4 Qe7 8.O-O g6 9.Nc3 Nh6 10.Qh3 e5 {Unfortunately for black, touch move is a rule that exists and only spotted the downfall after grabbing the pawn. (R.C)} 11.Qxc8+ Qd8 12.Qxd8+ Kxd8 13.Ne6+ Ke7 14.Nxf8 Nf7 {Either way, a piece will be lost, but taking the knight only helps white develop the bishop. (R.C)} 15.Ne6 Nd7 16.f4 Nb6 17.Bb3 exd4 18.Nxd4 c5 19.Nf3 c4 20.Ba2 Rac8 21.Be3 Nd7 22.Nd5+ Ke6 {A bold move but walks into a mate in one. Most likely as a result of being two pieces down and wanting the game to be over. (R.C)} 23.Nd4#
