Day 1

Surya Shekhar Ganguly took the lead by scoring 17 points (3 wins and 1 'equal draw') on the first day of his match against Sam Shankland.

The first game featured missed chances and beautiful tactics, but Ganguly capitalised on a blunder by Shankland (29.Ba3?) to dominate the position. In the second game, Shankland missed a winning attack and suffered a significant loss. The third game was an interesting endgame with bishop and 3 pawns against a rook - it was a very hard position for Shankland and Ganguly ended up winning the game. The fourth game was what is described by the format as an 'equal draw'.

After the games, the event organizer, Venceslav Rutar, joined the livestream on the ChessBase India YouTube channel and shared his opinion. (Find all details about the scoring system below in this article).

Game 1: Shankland 0 - 5 Ganguly

The match started off with this wild game where both players missed many chances and there were plenty of beautiful tactics. Here's the first one of them:

White actually built up a better position out of the opening, but this was a serious error from Shankland. Ganguly did not spot the refutation, played 14...Re7 and White found the nice 15.Nxb7! Rxb7 16. Rxc6 winning a pawn and getting a better position. But here Ganguly had a beautiful idea with 14...Re6! 15. Nxb7 Qe7! and the White Knight gets trapped and eventually captured.

Sam couldn't convert his advantage well, and this was the final mistake by him. Can you figure out how Ganguly finished off the game here?

Game 2: Ganguly 5 - 0 Shankland

Shankland built up a completely winning position with the black pieces, but things went south for him towards the end. This is a big chance he missed, one that would have allowed him to finish the attack:

The beautiful tactical shot 41...Ne1! finishes the game here for White. 42.Rxe1 is met with 42...d3! and soon Black wins the rook by force - the resulting position with queen and bishop for Black against the white queen should be comfortably winning.

But Shankland played 41...Qe4? and after 42.Qxe6 White is back in the game.

49...Kb8 was the losing mistake for Shankland - do you see why? White to play and win.

Game 3: Shankland 0 - 5 Ganguly

This game featured a study-like endgame consisting of bishop and 3 pawns against the rook. Practically, this is very hard for the side with the rook - Shankland in this case. But the entire game had so many beautiful resources!

We would invite our readers to study this game deeply, and leave you with two positions.

61...f4 actually lets the win slip away from Black. Can you find what should White play to hold the draw, and what should Ganguly have played instead?

This was the last chance for White to save the game - how should Shankland respond to 62...Kf5 by Ganguly?

Game 4: Ganguly 2 - 2 Shankland

Shankland managed to outplay his opponent in the opening and entered a better rook endgame with the black pieces. At one point, he did get a big advantage - but the way to win was not straightforward. After trading one pair of rooks, the game went on to end in an 'equal draw' which meant both players got 2 points.

The final position.

Day 2

Ganguly kept his good form from the last day, and closed the match itself by winning the fifth game -Shankland had no way of coming back in the match.

But the games went on - as the main idea of the match was to test out the Venceslav Rutar scoring system. Game 6 was a draw, and Shankland struck back to score his only win of the match in game 7. The eighth and last game of the match was an absolute rollercoaster, where both players had winning positions at some point, but the game finally ended in a draw.

Ganguly won the match by a 26-11 score!

Game 5: Shankland 0 - 5 Ganguly

Shankland created a very sharp position out of the opening, a Bogo-Indian system. It was a question of who would break through first on the kingside - and it was Ganguly who did it:

Do you see how Black started the kingside attack after 21.Qe2?

Ganguly broke through with the very nice combination 21...Rxf3! 22.Qxf3 Qh2+ 23.Kf1 Ngxf2! 24.Bxf2 Nd2+! to win the white queen.

The Indian GM went on to win comfortably with the black pieces!

Game 6: Ganguly 2 - 2 Shankland

This game was more or less a stable draw, but with a big missed chance in the opening. See if you can find it:

Ganguly played 14.Na5? which is a big mistake. Shankland replied by 14...Nd4 missing the refutation - can you find the best move for Black?

Game 7: Shankland 5 - 0 Ganguly

This was the best game of the match for Shankland, and the only game he won. He outplayed his opponent right from the opening, and scored a comfortable win.

The start of the queen endgame.

Game 8: Ganguly 2 - 2 Shankland

This was an up-and-down game with many chances for both sides. Ganguly got a completely winning position in the rook endgame, but made an unfortunate blunder. Can you spot the problem with this?

What was so special about this event?

The scoring system. Today, there are countless variations of chess. This is the first time that any scoring system has been developed which focuses on draws. The traditional scoring system divides the points equally between the two players. This rule has been followed for many centuries. Draws are an integral part of chess, and we cannot eliminate them ever. While no one can really convince the players to fight for a win, one person decided to change the rules. He created such rules that would make players fight for a win.

If they can't win the game, change the rules!

The traditional scoring system with 1 point (to the winner), ½ point (to both the players), and 0 points (to the loser) is replaced by a system with 5 possibilities.

Points for the winner and loser are self-explanatory. But, when the game is declared as a draw, the tournament director will count all the pieces on the board. The material balance will be calculated by adding values as follows:

The player who has more pieces on the board (material advantage) will get 3 points (favoured draw) and the other player will get 1 point (disfavoured draw). If the material advantage is the same for both players, then both will get 2 points.

Let's see some draw scenarios to understand this better:

Master Class Vol.17 - Boris Spassky

In this video course, experts including Dorian Rogozenco, Mihail Marin, Karsten Müller and Oliver Reeh, examine the games of Boris Spassky. Let them show you which openings Spassky chose to play, where his strength in middlegames were and much more.

This system does not change the following possibilities that result in a draw:

• Agreement between players
• Bare kings
• Stalemate
• 3-fold repetition
• 50 reversible moves in a row

What about the "timeout vs insufficient material"?

Let's consider two scenarios to understand this.

1. Player A has only one bishop and Player B has only one knight. If player A flags, then he will get 1 point (disfavoured draw) because he ran out of time and player B will get 2 points (equal draw) because of equal material.
2. Player C has one knight and Player D has a king only. If player C flags, then he will get 1 point (disfavoured draw) because he ran out of time and player D will also get 1 point (disfavoured draw) because of insufficient material.

Why this system?

If we take a closer look at the drawn games, we will notice that sometimes giving half a point to both players appears unfair. A draw might be unfair in the following two situations:

1. Sometimes a player might have a clear advantage on the board with material advantage, but still end up in a stalemate / 3-fold repetition situation.
2. A player with a winning position might run out of time but still draw due to insufficient material on the opponent's side. This can be unfair to the player having a winning position.

This scoring system tries to bring justice in such unjust situations. We must accept that all draws are not equal.
