1. e2-e4 e7-e5 2. g1-f3 b8-c6
3. d2-d4 e5xd4
4. f3xd4
f8-c5 5. d4-f5 ...
Here is a theoretical mistake in that White may incur due to ignorance, as has been seen many times in practice. The black response, somewhat cold and spectacular, gives advantage to the second player in all forms. You have to play 5. c1-e3.
5. ... d7-d5!
Black has calculated line 6. e8-f8 f5xg7 + 7. g7-d8-h4 h5 8. h5-g3 g8-f6 9. f1-e2 c6-e5, 10. h2-h3 h8-g8 with better play and strong attack. But White can fall into a new error, which leaves everything resolved.
6. e4xd5? c8xf5
7. d5xc6 c5xf2 +
And at 8. e1-e2-g4 + \u200b\u200bf5, White has retired.
