Oct-17-21  fabelhaft: 34. … Bxh5 was Swiercz’s chance. He misplayed the opening and was down to increments with a lost position already by move 20. Caruana had lots of time and it never looked as if Swiercz would have a chance but he did get one there even if he didn’t see it and probably would have lost anyway given his clock situation.

Oct-18-21  Ulhumbrus: If after 6...Bc5 White is able to exchange his b pawn for the more valuable e5 pawn after 7 b4, one alternative is 6...Nxd5 7 cxd5 Ne7.

  LRLeighton: Ulhumbrus, I think that you miscalculated that, or there is a typo -- after your line, simply 8 Nxe5 leaves white up a pawn.
Oct-18-21  Ulhumbrus: <LRLeighton> You are right. Black can't answer Nxe5 with ...Nxd5. In that case he may have to settle for 6...Be7.
