Carlsen vs. Nepomniachtchi: World Championship – Game 6 Part 3

Greetings chess players. My name is Chris Torres, and this is Daily Chess Musings’ Special Coverage of the 2021 FIDE World Championship Match between Magnus Carlsen and Ian Nepomniachtchi. Because of the historic importance and lengthy nature of Game 6, I broke this round into three videos. Tonight, we are examining Part 3 of Game 6 from the 2021 FIDE World Championship Match between Magnus Carlsen and Ian Nepomniachtchi.

In our third and final installment for Game 6, we will witness Magnus squeezing blood out of stone in the form of a pressing for a win against Nepo in an ultra-complicated endgame that was objectively evaluated as a draw in computer table-bases. In order to triumph, Carlsen disregards the famous endgame wisdom of placing a rook behind passed pawns and in fact, placed his rook in front of his passed pawns in order to the white pieces forward. Doing so meant that Nepomniachtchi needed to play like a computer to draw and under the circumstances, playing with 100% precision over scores of moves against Magnus was just too tall of a task for Nepo or any other chess player alive today. Game 6 of the Carlsen-Nepomniachtchi Match will probably go down as Magnus Carlsen’s greatest endgame so far and undoubtedly the greatest endgame triumph ever in a World Championship Match. In total, it took Magnus Carlsen 136 moves and 7 hours 45 minutes, setting the all-time record for the longest game in the history of the World Chess Championship, in order to defeat Ian Nepomniachtchi and take the lead in the 2021 FIDE World Championship Match.

So, without further ado, let’s examine the thrilling conclusion to Game 6 of the 2021 FIDE World Chess Championship Match…

Magnus has a rook and knight + three pawns vs Ian's Queen and pawn.It's worth noting, that white is the only side playing for a win here as black has no passed pawns. However, in compliacted and imbalanced endgames there is a greater chance for a decisive result. The human factor needs to be added to the equation with both players having already been at this game for 7 hours the chances of losing a World Championship Match Game with one miscalculation is very real.} 83.Ra6+ {Magnus is really the only player with a reason to play for a win because of his passed pawns. However, advancing those passed pawns without allowing the black queen a forking opportunity or to inintiate a perpetual check will be very challenging.} Kh7 84.Ra1 Kg6 {Ian is waiting to see what Magnus has in store.} 85.Nd4 Qb7 86.Ra2 {Stopping Qb2+.} Qh1 {So Ian threatens Qh2+ or possibly h4 which would exchange pawns and expose white's queen.} 87.Ra6+ {But Magnus plays a check before Ian can. Magnus is giving Ian lots of checks which are also opportunities for black to go wrong.} Kf7 88.Nf3 {Guarding against Qh2+.} Qb1 {But Ian is is handling the pressure beautifully and prepares to check with Qb2.} 89.Rd6 {Now if blacks queen checks from the second rank, Magnus can interpose with Rd2.} Kg7 90.Rd5 Qa2+ 91.Rd2 {As expected.} Qb1 92.Re2 {Perhaps from e2, Carlsen's rook can support white's e-pawn advancing.} Qb6 {So Ian immediately pins the pawn on e3.} 93.Rc2 { Magnus must go back to the drawing board to find a way to coordinate his pieces in such a manner that his passed pawns can advance. Again, he must do this without allowing Ian a material gaining tactic or perpetual check.} Qb1 94.Nd4 Qh1 {Again, trying for Qh2+ or a possible pawn advance to h4.} 95.Rc7+ {Carlsen, again, checks the black king before Ian can play Qh2+.} Kf6 96.Rc6+ {Again, all of these checks offer black opportunities to error.} Kf7 97.Nf3 {Again, guarding h2 from black's queen.} Qb1 {So Ian threatens Qb2+ again.} 98.Ng5+ Kg7 {Ian continues to play accurately out of Carlsen's checks.} 99.Ne6+ Kf7 100.Nd4 {So if Qb2+, the white rook can step in the way.} Qh1 {So Ian returns his queen to h1 to threaten Qh2+.} 101.Rc7+ {Once again, Magnus checks the black king beofre Ian can play Qh2+.} Kf6 102.Nf3 {Once again, to guard against Qh2+.} Qb1 {And Ian is once again eyeing Qb2+.} 103.Rd7 {Preparing to block Qb2+ with Rd2.
