          Rd 1 MVL brilliant win.

          https://www.chessbomb.com/arena/2021...rov_Shakhriyar Its amazing how simple White's plan is So simple and yet so deep. It took the computer a while to catch up. The plan involves a stagnant isolated D pawn for Black and long range plans for White's C pawn. Hat's off to Wesley So!

          Sam Shankland got totally out maneuvered by Fabiano Caruana. Not easy to do but Fabiano's technique was awesome. The final position is a great example of zugzwang. https://www.chessbomb.com/arena/2021...-Shankland_Sam

          Fabulous Fabi, MVL, and Wesley So off to a great start.

            Nice to hear discussions by Alejandro, Maurice, and Uncle Yaz on positions from the So-Shak game. Apparently very interesting and unclear - long term transitions to bishop and rook vs rook endgames.

              Sinquefield Cup 2021

              August 17, 2021


              Round One

              Alexander Grischuk, Simon Williams and Andras Toth are handling the games at chess24.

              This Sinquefield Cup tourney did not advertise itself. I only knew yesterday who the participants would be. Aronian, Grischuk, Radjabov and Giri were all scheduled to play but withdrew for a variety of reasons.

              One feels for Grischuk commentating, starting at 11 PM his time.

              Round 1, August 17
              So, Wesley – Mamedyarov, Shakhriyar

                Wesley So wasted opportunity, on the other hand nice save by Shak.

                  Looks like Rex got his wish. Four games into the endgame and two past seven oclock.

                    Sinquefield Cup 2021

                    August 18, 2021

                    Round Two


                    On the chess24 site the commentators are Grischuk, Williams and Toth.

                    Andras Toth is a chessable author. This is his bio:

                    Andras is a streamer, Youtuber, and a well-known coach based in Australia. He specializes in adult improvement, as his online content often shows. However, he has coached several Australian Junior Champions -some going from under 2000 to IM during their collaboration-. Being awarded coach of the year in Australia for 2007, he captained Australia's ladies team to the 2008 Dresden Chess Olympiad.

                    He is a two-time junior Champion of his native Hungary and a pupil of the legendary coach, IM Lazlo Hazai, who was instrumental to the Polgar sister's chess development. Andras pays enormous tribute to him for influencing his love for chess, literature and helping others improve through his coaching.

                      Wesley So was the only winner in rd 2. His reward? A tie for first with Fabi, MVL, and Dominguez. (where he should have been after round 1)

                        Rd 3 Classy resignation by Peter Svidler. The final position is beautiful. (the logic of the variations following). Black will be at minimum two pawns down with no counterplay. Very nice play by Wesley So.
                        Poor Sam Shankland must have miscalculated the king and pawn endgame. (his earlier Ng4 turned out to be justified but then comes the endgame)
                        Rex must be smiling about Fabiano's connected passed pawns on the 6th and 7th (supposedly worth at least a rook)

                          and we have the bonus of Shak and Richard Rapport madly trying to checkmate each other.
                          Still with all that going on, the Sinquefeld Cup is averaging three endgames per round. Pretty good.

                            Jeffery Xiong has three draws, holding above his level. Very good! Keep it up!

                              Some crazy variations in the Shak - Rapport game. Great entertainment! Will Shak find his way through?
