Stockfish begins by developing a legal-move tree, whence it must evaluate the resulting board positions. That is, the computer has to look at the pieces on the board and decide whether that arrangement of pieces is “good” or “bad.” The way it does this is by using an evaluation function.
When do you use tapered Eval in stockfish?
In Stockfish it is never applied for positions where king of either side is in check. Resulting value is computed by combining Middle game evaluation and End game evaluation. We use Tapered Eval, a technique used in evaluation to make a smooth transition between the phases of the game. Phase is a coeficient of simple linear combination.
How does Stockfish evaluate a dynamic chess environment?
