Mateo: The Black King showed no fear of ghosts and went in the middle of the game accross the board in White's area. Petrossianlike!Another interesting King march was possible, if White, instead of 19. hg? leading to disaster, had played 19. Qa7!?. After 19... gf 20. Qa8 Kc7 21. Qa5 Kd7! 22. 000 Ke7!, it seems that the bold King can escape to danger.
If 23. Qe5 the simple Rd3! is good enough, with 2 pieces for Rook + pawn. 23... Rc8 24. Rd4 f2! 25. Rf1 (25. Qe4 Qe4 26. Re4 Rc4 27. Rc4 Bc4, Black wins; 25. Re4 Qe4!) Qg2 26. Kc2! Rc5! (not 26... Qf1 27. Qg7 with a draw)27. Qe4 Qf1, Black wins.
If 23. Qc7 Kf6!, the King is safe. Black wins.
If 23. Rhg1 (best) Qh6! 24. Qe5 Nd6! with a big edge for Black. White has not enough compensation for the piece.
