A horrible move to play, but there's nothing much better.
1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. c2c3 An interesting and popular Sicilian sideline. 3... g8f6 4.Be2 is historically the main move, but the one played and 4.Bd3 are also quite popular. 4. h2h3  4... c8d7  5. f1d3  5... b8c6  6. d3c2  6... a8c8  7. e1g1  7... g7g5 A new move and an unsuccessful one. This idea is known in similar positions, although not in this exact one. Black could achieve a good position, were it not for White's accurate reply. 8. d2d4 This is also well-known from similar positions. 8... g5g4  9. d4d5  9... g4f3  10. d5c6  10... d7c6  11. d1f3  11... h8g8 This is Black's best option; he should forget about castling. 12. f1d1 This allows Black a difficult move to activate the queen, reducing White's advantage. 12... e7e6  13. b1d2  13... b7b5 Prevents the knight from going to c4, but this opens the queenside and makes things even worse. 14. a2a4  14... a7a6  15. a4b5  15... a6b5  16. d2f1 White is just positionally winning. Black's king has nowhere to hide. 16... f6d7  17. f1g3  17... d7e5  18. f3h5  18... g8g7  19. g1h2 A good plan, preparing f2-f4. 19... d8f6 It's hard to offer recommendations, but it's clear that this move doesn't improve Black's position. 20. f2f4  20... e5d7  21. h5e2  21... f6d8  22. e4e5 One of many good moves for White. Maybe this one is the most incisive. 22... d8h4  23. g3e4
