ChemMac: Mordimerchess: if 30...Rf6, then I think that 31 Rh8 Kf7 32 Rc8 Nc8 33.Bf8 Kf6 34 Qc5 Kf7 35 Qc5 Nb6 36 a4! because Na4 loses the N. This is just in my head; not computer analysis. W will win a P and win easily. OK?

ChemMac: The player list has none of the other top players in it - no Caruana or Nakamura for example. So Carlsen is all alone against, yes, 2700+ opposition, but all much lower-rated than he. All I can say: interesting.
   Apr-29-20 Ding Liren vs Nakamura, 2020 (replies)
ChemMac: A blunder in anv even position: 28. Kg2?loses a Rook. Just 28. RXd8 and it's virtually even per Stockfish.
   Apr-26-20 Magnus Carlsen Invitational (2020) (replies)
ChemMac: In the second example.
   Mar-22-20 Nepomniachtchi vs H Wang, 2020 (replies)
ChemMac: I thought that White should have played 43 Nh4 Then 43.....Kd5 44 Ng6 KXc5 45. Nf8 Kd6 46. Nxh7 Ke7 47. Ng5 Kf8 48.Nd4 and doesn't this win easily? I haven't checked this on a chessboard, let alone with a program...

ChemMac: <A bold statement which cannot be proven true; because so called 'master players' simply refuse to play against engines. That said, so called 'master players' have made more silly statements about engines than vice versa :P> Many quite genuine 2400-plus players I know do play ...
   Jun-21-18 Kramnik vs So, 2018 (replies)
ChemMac: <GreenLantern> Krammik was quite lost at that point.
   Jun-20-18 Topalov vs T Paehtz Sr, 2017 (replies)
ChemMac: Resigning here...a pawn down and a poor position, after even say 16...a6 17.RXb7 Nf6. But against Topalov, not worth continuing.
   Jun-14-18 Your Next Move (Rapid) (2018) (replies)
ChemMac: <jphamlore> There were already three novels in print called ,"The Mating Game", AND a psychology book and one about, I think, about wolves, AND there was a movie. Houska could have changed her title a little.
   Jun-07-18 Caruana vs So, 2018 (replies)
ChemMac: Offsetting mistakes due to time pressure and So not realising he'd played his 40th move? 40. h3? (just 40. BXb7 wins easily) and as mentioned 41...Rd3?
