What Do the Numbers and Bars Mean Next to Each Move

Hello,

I'm a beginner to chess. Can anyone tell me what the numbers and bars mean next to each move? 

Many thanks

It's the engine's (computers) evaluation of the position. A positive value indicates an advantage for white, a negative value indicates an advantage for black.

eg.

+1 means that white has an advantage equivalent to 1 extra pawn of material.
-1 means that black has the same advantage.

If white gave away a free Knight in the opening, for example, you'd notice the evaluation shift from approximately 0 to -3, which means black's advantage is now equivalent to three pawns worth of material - which it would be as the Knight is worth 3 points.

Typically 1 pawn = 1 point of material, a Knight or Bishop = 3, a Rook = 5 and a Queen = 9.


Sometimes the computer will evaluate a piece to be worth more or less than its typical value dependent on the position. eg. towards the end of a game, if you both have 1 king and 1 queen each, and one side gives away a free queen in that position, rather than showing + or - 9 for the other side, it might re-evaluate the position as something like this "#5" this means it's calculated a forced checkmate line in a minimum of 5 moves. Aside from + or -, you may see # - this symbol generally signifies a "forced checkmate in X moves".

These bars are time per move.

Hi there,

Many thanks for your replies. 

So using Manekapa's image as an example, next to the bars, the numbers 4.0, 4.0, 11.0, 2.9, 8.9, 19.6...or at move 16, it's 25.1, 4:02.2...

What do they mean?

Thank you

4.9 means it took 4.9 seconds to play that move by a player. 4:02.2  means it took 4 minutes and 2.2 seconds to play that move. Player thought for 4 min 2 seconds before playing the move

OK thanks.

I actually didn’t know that that was helpful

In a game:

Number: A numerical value placed on the move that you are currently on

Bar: A bar that signifies the length of time taken to make that move

When analysing:

Number: A numerical value that places one's advantage over the other (+'s for white, -'s for black)

Bar: An evaluation method to visualize who is better. Whichever part of the bar is bigger has the advantage.

How do you get the evaluation bar onto the left instead of in the analysis? Pls, help!

Any number over or under 20 is just Stockfish mocking the players. For instance plus or minus 60 is common in end games even though there are two kings and rook left on the board.

A very high evaluation such as that means that Stockfish cannot see a checkmate, but it can see a position which leads to checkmate.
