In her notes for Torre & Cavallo Scacco!, No. 11, November 2008, pp. 15-16, Sedina attached an exclamation mark to her last move, as “White tries to exploit the weakness of the squares b6 and b7 after Black’s premature light-square Bishop”.

18. h3? “Apparently, I did not remember the en passant rule! After 18. dxe6! fxe6 (there is nothing to fear from 18. ... Qh4; for example: 19. exf7+ Kh8 20. h3 Nxe3 21. fxe3 Rab8 22. Qxa6 Rxb2 23. Rab1 Rc2 24. Qa4 Re2 25. Rf3 and White’s material advantage should guarantee her a win, even though the conversion is far from simple) 19. Rad1 Rb8 20. Qxa6 Rxb2 21.

21. Rab1 Rb8 22. Qc6 Bxb2 23. Kh2?! 23. Kh1 seems to be a better square for the King, but then Black would probably continue 23. ... Rb4 with an edge.

29. e5? After this mistake — probably due to Sedina’s time shortage — it’s all over. 29. Qe2! still offered hope.
