The 2nd International Tournament at Bari, Italy, from August 9–23, 1970, was not the happiest one for Wolfgang Unzicker, who experienced most, if not all of the vicissitudes of a German tourist visiting Italy in summer. As wrote Bernard Zuckerman in his article “Tournament at Bari”, Chess Life & Review, Volume XXVI, No. 1, January 1971, p. 11, “Grandmaster Unzicker of West Germany was not in good form in this tournament. He was soundly trounced in the first round by the talented young Italian master, Cosulich, who incidentally, made the first leg of his international master title at this event”. But Unzicker’s misfortunes have not been limited to the board: “Besides his loss to Cosulich,
Unzicker was upset by the fact that his car was broken into and some of his money stolen”, writes Zuckerman. “In fact, he postponed his game with Tatai for this reason”.

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. Bxc6+ bxc6 6. d4 Bg4. In his annotations for Chess Informant, No. 10/1970, 302, p. 94, Grandmaster honoris Caïssa Enrico Paoli, maybe too influenced by the outcome of the game, gave his preference to 6. ... f6! (even the punctuation is his).
7. dxe5 dxe5 8. Qxd8+ Rxd8 9. Be3! 9. Nfd2 f6 is assessed as equal by theorists. Likewise 9. Nbd2 f6 10. Nc4 Be6 is perfectly fine for Black; for example: 11. Ne3 Bc5 12. Bd2 Ne7 13. Ke2 Nc8 14.

9. ... Bd6. 9. ... f6! 10. Nbd2 Be6! (Paoli) is a suggestion worthy of attention.

13. ... Rb8? The question mark is from Paoli, who recommends 13. ... c5 14. Nb3 Be6 15. Nca5 Rb8 16. Bxc5 Bxc5 17. Nxc5 Rxb2⩱ with Black being slightly preferable, but he evidently overlooked that White is not compelled to capture on c5. Much better is 16. 0-0-0! (instead of 16. Bxc5?), retaining the Pawn and keeping the bind. There might then follow 16. ... Rb5 17. c4 Rb4 18. Bxc5 Ra4 19. Bxd6 cxd6 20. Rhe1 Bxc4 21. Nb7! Bxb3 22. Nxd6+ Ke6 23. axb3 Rb4 24. Nc4 Rxb3 25.

20. g3! With methodical consistency, Cosulich conquers the board. One can only note that 20. Nxe5! fxe5 21. Bg5+ Kd7 22. f4! is another way to crush the defendant (28. ... exf4 29. e5+−).
20. ... Nb6. Neither 20. ... Ke6 21. f4+− nor 20. ... g5 (hoping to prevent, as far as possible, the advance f2-f4) 21. Nxe5! fxe5 22. Bxg5+ Kd7 23. f4!+− helps.
21. Nxd6 cxd6 22. Bxb6 Rxb6 23. Nc4 Rbb8. If 23. ... Rb7 then 24. Nxd6 Rbd7 25. Nb7+− (Paoli).
24. Nxd6 c5 25. Nxe8 Rxd2 26. Rxd2 1–0. Whether Black retakes with King or Rook, White will gain a second Pawn by 27. bxc5 and have an easily won ending.
