The following game, published by Massimiliano Enzo Maria Orsi on his own website Italian Castling, which features a constantly updated archive of Italian chess history, if nothing, dispels any myth that Roberto Cosulich’s “theory of openings” lay on sheer improvisation.
Roberto Olivotto – Roberto Cosulich
16th Italian Team Chess Championship; Venice, November 2, 1976

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. Be3 Nf6 6. Nc3 Bg7 7. Bc4 0-0 8. f3?! A dubious line which gives Black a temporary upper hand.
8. ... Qb6! 9. Bb3. The only move to hold the balance. If, instead, 9. Bb5? then 9. ... Nxe4! with White’s position in tatters, Kelečević – Cosulich, 13th International Festival, Imperia 1971.
9. ... Ng4! Also good is 9. ... Nxe4! 10. Nd5 Qa5+ 11. c3 Nc5 12. Nxc6 dxc6 13. Nxe7+ Kh8 14. Nxc8 Raxc8 15. 0-0 Rcd8= with a soon draw, R. J. Fischer – Panno, Interzonal Tournament, Portorož 1958.
10. Nd5. 10. fxg4 Bxd4 11. Bxd4 Qxd4⩱ also slightly favours Black due to his sounder formation, Sakharov – L. Z. Stein, 32nd USSR Championship, Kiev 1965.
10. ... Nxe3 11. Nxb6 Bxd4!
9. ... Ng4! Also good is 9. ... Nxe4! 10. Nd5 Qa5+ 11. c3 Nc5 12. Nxc6 dxc6 13. Nxe7+ Kh8 14. Nxc8 Raxc8 15. 0-0 Rcd8= with a soon draw, R. J. Fischer – Panno, Interzonal Tournament, Portorož 1958.

10. ... Nxe3 11. Nxb6 Bxd4!
12. Qe2? This is White’s losing mistake. Comparatively best was 12. Nxa8 Nxd1 13. Rxd1 Be5⩱ leaving Black with a somewhat better position — but nothing irremediable.
12. ... Bxb6. It does not take a chess engine to tell that in such a position the three pieces are much stronger than the Queen.
13. c3. Likewise after 13. Kd2 Na5 14. h4 Nxb3+ 15. axb3 d5! 16. h5 dxe4 17. hxg6 fxg6 18. Ra4 Bf5 19. g4 Rac8 20. c3 exf3 21. Qh2 Nf1+ 22. Rxf1 Rcd8+ 23. Ke1 f2+ 24. Rxf2 Bxf2+ 25. Qxf2 Bxg4 26. Qxf8+ Kxf8 27. Rxg4 Kf7 Black triumphed, Zagorovsky – Simagin, 29th Moscow City Chess Championship, Moscow 1951.
13. ... Rd8! 14. g4 Na5 15. h4 Nxb3 16. axb3 d5 17. h5 g5! Game over.
18. Ra4 dxe4 19. Rxe4 Rd1+ 20. Qxd1 Nxd1 21. Kxd1 Be6

White’s uncoordinated Rooks are no match for Black’s powerful two Bishops and Rook.
22. c4 h6 23. Kc2 Bc7 24. Rd1 Bd6 25. Ra1 a5 26. Rd1 Kg7 27. Kc3 b6 28. Kd3 Bd7 29. Ke2 Bc6 30. Re3 Rf8 31. Red3 f5 32. Rf1 fxg4 33. fxg4 Rf4 0–1.
