Apr-06-04  Bobsterman3000: This is a great win.
Apr-06-04  xu fei: 26...Qe6 27.Bd4 Kg7 28.Rg5+ , it took me a while to see the pin.
May-07-04  Elrathia Kingi: What if 26...Qe4?

  Benzol: Correction, it's not mate but Black must play ♕g6 and White can snap off the Black Queen.
Jul-14-04  PivotalAnorak: What if 22... Bxe3 ? If pxB then pxR, and White's black sq B is gone, Black being the exchange up. If R moves then Bc5 (or if Rfd6 Bg5), defending the R on e7.
Jul-14-04  tud: 22 ... Bxe3 23 Rfd6
Jul-15-04  PivotalAnorak: tud: 22... Bxe3 23 Rfd6 Bg5 (with the Re7 attacking White's Q) followed by Bf6. I think Karpov didn't believe in Portisch's sacrifice and wanted to refute it, else he wouldn't have taken the R on f6, what do you think ?
Jun-01-08  Marmot PFL: 25...Kh8? was just a blunder. After 25...f5 I doubt white could even draw. Karpov's only loss in San Antonio, where he tied for 1st with Portisch and Petrosian.
Jun-02-08  najdorfman: Fritz indicates four consecutive blunders--both players on each of their 24th and 25th moves! White should have drawn witth 24. Qg4+! Kh8 25.Bxd4 Re6 26. Qf3 Kg7 27. Qg4+ Kh8 28. Qf3=. After the game's 24. Rxd4?, Karpov missed 24...Rc8! with a clear advantage. Then Portisch missed 25. Rg4+ Kh8 26. Qf3 Qd6 27. Rd4 Qe6 (if 27...Rxe3 28. Qxe3 is good.) 28. Re4 Qxe4 29. Qxf6+ Kg8 30. Bd4 Qxd4 31. Qxd4 with a tiny edge for White. Finally, Karpov's 25...Kh8?? was properly exploited by Portisch. The game might have finished with 26...Qxb2 27. Bd4 Qb1+ 28. Kh2 Re6 29. Bxf6+ Kg8 30. Rg5+ Qg6 31. Qf5 etc.
Sep-15-14  johnkr: After 25...f5 try the move 26 Rf4!? It's likely that after Qxb2 27 Bd4 Qc1ch 28 Kh2 Qc7ch 29 Be5 =.
Jan-20-17  Albion 1959: Their first encounter is a win for Portisch. This gave him a plus score against Karpov ! But as we all know it didn't last long:
