Engines evaluate a position based on a number of factors - material imbalance, king safety, control of the center, pawn structure etc. My understanding is that they then combine these separate evaluations using a weighting for each (which can be adjusted), to produce a final score for the position.

Is there an engine which can display a breakdown of the separate evaluations?

For example:

Material: 0.00 King safety: -1.21 Center control: +0.87

Which means that material is equal, but black's king is less safe than whites, and white has better control of the center.

Yes. Look at Stockfish 6. You can try it yourself.

MG -> Middle Game EG -> End Game

Most chess engines have a different set of evaluation or algorithm for an endgame. They could use it to model phase transition (e.g.: middle-game to end-game).

    That's confusing, what do MG and EG mean? Why are the white and black columns equal? Apr 25 '15 at 8:30

  • They're equal because the initial position is symmetry. Anything that black has is also something white has. Overall, the balance of the position is equal.

  • Also, how do you get that analysis? Which commands do you have to run? Mar 14 '19 at 17:04

Toga Log also gives a breakdown of its evaluations.
