Beating a GM in blitz

It’s difficult to determine the exact odds of beating a chess grandmaster if you are rated 1900 ELO, as it depends on a variety of factors such as the grandmaster’s rating, their current form, and the time control of the game. However, generally speaking, the odds of a 1900-rated player beating a GM in a standard time control game (90 minutes for the first 40 moves, followed by an additional 30 minutes for the rest of the game with an increment of 30 seconds per move) are extremely low.

According to statistical analysis, the average ELO rating difference between a grandmaster and a 1900-rated player is approximately 600-800 points. In chess, a rating difference of 400 points usually indicates a 10 to 1 difference in strength, so the odds of a 1900-rated player beating a grandmaster would be roughly 1 in 1000.

However, it’s worth noting that upsets can and do happen in chess, and sometimes lower-rated players are able to pull off a win against higher-rated opponents due to factors such as mistakes, blunders, or unexpected opening choices. In the end, the outcome of a chess game depends on many variables and is never a certainty.

The Tarrasch Defense

The chess game in question is a Tarrasch Defense with Black pieces against White’s d4 opening. The game shows a lot of potential for both sides to make creative moves, but also highlights some significant mistakes that can occur.

On the positive side, Black’s use of the Tarrasch Defense is an aggressive and double-edged opening that can lead to some exciting play. Black’s 11th move with Na5 was a strong one, as it puts pressure on White’s queen and allows Black to control the center of the board. Additionally, Black’s use of Rc8 to control the c-file and the second rank, along with their move to cut off White’s king at the end of the game, demonstrate strong positional play.
