In chess notation, what do the decimal numbers mentioned after a move mean?
For example 5. Bf4 (0.24) O-O (0.27).
What do the 0.24 and 0.27 mean?

these are chess engine evaluations of the percentage of a pawn that the silicon beast
thinks that there is an advantage/disadvantage in the position, thus 0.24 is 0.24 of a
pawn, a pawn being the unit of measurement in chess. This essentially means that the
position is equal, 0.24 of a pawn being meaningless.

Ahhhh Boggles - I was wrong.
I was fooled by:
"....decimal numbers [b]mentioned after a move."
Books 'mention' - computers 'display'.
Jakal turn that thing off it will only confuse you.
Read a chess book.[/b]

Originally posted by greenpawn34I've never seen a book where those were published, and frankly, I hope I never do. To the player, those times may be important, but to the reader, they're completely meaningless.
Typical of Robbie the Robot to think the lad is using a computer.
The OP is reading something called a chess book
The numbers in brackets will be the current times on the clock.
Giving you an indication of how long a player thinks over certain moves.

Mind you, so are the computer's evaluations, I agree with you on that at least.

Originally posted by utherpendragonI would have trouble trying to agree less. The numbers, without fuirther human explanation of the specifics of the position, are meaningless.
White has a decisive advantage +- the numeric equivalent would be 0.95-0.85
Equal position = or 0.55-0.45
Black has a decisive advantage -+ 0.15-0.05
And so on and so forth.
According to the book, clearly the numerical values enables a judgement to be expressed more precisely.
For instance, instead of just "White stands better", you can c ...[text shortened]... rate play.
Or, "Whites winning chances are about equal to Blacks drawing chances" (0.75)
Originally posted by greenpawn34Now, here's the thing: I think those comments are certainly worthwhile, and the facts significant. But's it's the fact that Bronstein thought it worth mentioning them, and explaining why, which makes them interesting, not the mere numbers.
Bronstein thought adding the times would benefit a student and gives a game with times and a very interesting looking graph based on the times taken in the game Barondregt - Bronstein 1965. (The Sorcerer's Apprentice - page 237).
You see at a glance where Bronstein had his longest think. move 23...Bf8 13 minutes.
His 2nd longest was 9 minutes on deciding to take offered gambit pawn on move 4.
