Chess Log: 1. d4 d5 2. ♗f4 e6 3. a3 ♗d6 4. ♘f3? ♗xf4 5. ♘e5 ♗xe5 6. dxe5 ♘c6 7. f4 ♘ge7 8. e3 d4 9. ♗b5 O-O 10. ♗xc6 ♘xc6 11. O-O dxe3 12. ♕f3 ♕d4 13. ♖d1?? e2+!! 0-1 {White resigns}

Well, what is there to say about this? What could White have done on his 13th move? Kh1 or c3 would've been an improvement over the game move. ♕e2 might've been even better. After the game moves, White could've continued with 14. RxQ E8=Q+ 15. Qf8 QxQ 16. KxQ and been down only a Rook and a piece. 14. Kh1 loses very quickly whether Black responds with e7xR=Q+ or QxR+.
