Why do GMs repeat moves instead of offering a draw?

A repetition giving the opponent the opportunity to claim a draw is a de facto draw offer but not a de jure draw offer. What does that mean? Well the "de facto" part means that in practice ...

Positional thinking by Grandmasters

When a GM, or even lesser strong players reach a position that is totally unfamiliar, they have to break it down into components. They evaluate the following for BOTH sides. In general, a lot of this ...

Why do high rated players still take so much time to calculate a pawn endgame position close to a game that they (likely) had before?

But I thought at that level this position must have already occurred, or, more likely, be somewhat close enough to a previous one, that the players would play in a more automatic fashion. Not true. ...

How is the life of a professional GM with ELO around 2500?

I know a few GMs in 2500-2600 range who would be considered professional -> ie chess provides the primary means of earning income for them. It is very hard work with wages not matching the effort/...

What is the best strategy for an amateur to last as many moves as possible against a GM?

It really depends on what you mean by "lengthen". I am not a GM, but as an "ordinary" Master, I have played 1700s before, who were lost by move 10, but the game still took 50 moves to finish. If you ...

The short answer Yes, they do, although very few GMs do and by a margin of less than 10%. This does not seem to be due only to random factors (see long answer). An example is GM Joseph Gallagher. As ...

Why do GMs repeat moves instead of offering a draw?

In many top level tournaments you are not allowed to offer a draw before a certain number of moves are played (often 30 or 40). The purpose of such a rule is to prevent very quick draws. However, one ...

It really depends on what counts as a missed checkmate. In Blitz we occasionally see a missed mate in 1. In slower games, mates in a few moves are rarelly missed. But the problem is that sometimes ...
