 | | offramp: Black's queen seemed to have very itchy feet.
In the end, Black is going to lose his b-pawn, leaving White with three connected passed pawns, as well as having ♗♗ v ♘♘. I think the problems started when he castled queenside. |

| Aug-01-20 | | utssb: 11...d5 was pretty ambitious since after 11...Be7 it seems like Black is fine. 11...Be7 12. Ndb5 ab5 13. Nb5 Qb8 14. Nd6+ Bd6 15. Qd6 Qd6 16. Rd6 might be interesting. I guess 14...0-0-0 is in view of 14...Be7 15. Nf5 |

| | offramp: Here is a small oddity. This is the final position in this game:

Carlsen as White has 2 bishops versus 2 knights. In the first round, Svidler vs Carlsen, 2020, this was the final position.

Svidler has the 2 bishops against the 2 knights, but here he resigned. |

| Aug-02-20 | | MordimerChess: According to Garry Kasparov the problems started with playing together Qc7 and Nbd7. It just doesn't work because black doesn't have any counterplay and any chances for the initiative. The point is that black has to watch Ndxb5 which gives white clear connected 3 passed pawns for the knight (pawn d6 also falls). But it has been played plenty of times in 21st century, with 11...d5 and even with some draws. But all the draws happened after 12. Nxd5 and they weren't that impressive, rather fast draws. Magnus Carlsen showed that he understands the opening much better but still... Peter had opportunities to complicate the games, for example 14...b4 looks pretty crazy but it gives black some counterplay with bxa3... but the position is very tough already.

| Aug-02-20 | | saturn2: What follows after 13...e5 ?
14. Nxd5 Nxd5 15. Nxb5 axb5 16. Qxd5 Rc8 and c2 and the Bf4 are attacked 14. Ndxb5 axb5 15. Nxd5 Nxd5 16. Qxd5 Rc8 same as before maybe it is because of lines like that:
14. Bxe5 Qxe5 15. Ndxb5 axb5 16. Bxb5 Be7 17. Nx-
d5 Qxd5 18. Qxd5 Nxd5 19. Rxd5 Ra7 20. Rhd1 |

| Aug-02-20 | | SChesshevsky: Really not up on the latest Sicilian Najdorf or Scheveningen theory but the old view was that ...0-0-0 is usually asking for trouble. Seemed like Svidler wasn't going with theory but just winging it anyway. In the broadcast, announcer Jan G. summed it up saying he read in Polugaevsky's book that "if Black goes ...0-0-0 something usually went wrong in the opening." Assuming it was in "Sicilian Labyrinth" by Polugaevsky. He should know, being a Najdorf expert. But even he can get caught in this tricky defense. Timman vs Polugaevsky, 1973 |

 | | saffuna: Carlsen won easily after 15. Be3, so no criticism. But would 15. Bxb5 have won as well?
15. Bxb5 axb5 16. Ncxb5 and the black king looks awfully exposed. Black's bishops do still cover a lot of white's entry squares for an attack, though. |

14. Nxd5 Nxd5 15. Nxb5 axb5 16. Qxd5 Rc8 and c2 and the Bf4 are attacked> I looked at it again. White has 17. Qe4 but it is no computer analysis |

| Aug-03-20 | | SChesshevsky: < saturn2: What follows after 13...e5 ? ...> Looks like 13...e5 is really committal with King still on the e-file. Feels like it either works good or goes down really bad. Guessing greater chance for the latter. With King in the center, white can even give up the Bf4. Maybe temporarily with something like 13...e5 14. Ndxb5 axb5 15. Bxb5 exf4 16. Nxd5 Nxd5 17. Qxd5 Rd8 18. Rhe1+ Be7 19. Qg5. Could be better play for Black after 13...e5 14. Ndxb5 but still appears scary and complicated and probably wouldn't want to play it unless certain it works out OK. |

| Aug-03-20 | | SChesshevsky: <saturn2> Interesting evaluation question after 13...e5 14. Ndxb5 axb5 15. Nxd5 Nxd5 16. Qxd5 Rc8. Maybe just simplify with 17. Qxd7 Qxd7 18. Rxd7 Kxd7 19. Bxb5+ is enough? The two bishops and triple connected passed pawns, though admittedly far from the goal, are probably sufficient compensation for the exchange. Chances of white losing might be small but wondering how much if any winning chances? |
