ok. the question is: do you see a game of chess as a number of
test-positions, like an EPD-file, where your engine only has to find the
accurate move, the BEST move, or that it avoids the wrong move ?

is chess only a number of positions you have to find the BEST move.

or is it possible to play moves, that are in the position the 2nd or 3rd best,
they do not instantly lose, they let the score of the opponent
increase because it saw: ough - not the "best" move here, that makes me happy.

but your engine plays those NON best moves because they are a subtarget
in a bigger plan,

lets say a normal program would have to push a pawn in position
move

30.  pawn push
31.  defend bishop
31.  recapture piece
32.  short-castle


those moves are the best moves your engine sees in the POSITIONS.

now lets say there is a different program, that has different mechanism.

it wants to bring a knight from the queen side to the king side of the board.
Why ? because the "target" is to use the knight in a king attack.

instead of playing the always best moves it tries to do a manouever.

this is not seen by the opponents because THEY expect your engine to play
BEST moves. so they are blind !

but - of course it weakes your position. so you need extra knowledge to
judge if the knight, when brought to the king side, makes sense.

i think, when replaying games of lasker, tal and fischer, that i can
see those behaviour of them in their games. that makes it for
computers so difficult to reproduce lasker,tal,fischer games.

because they do often not play the BEST move.

they sac the best move for the plan-move.


static against dynamic.

for me chess is more than finding key moves in a position.

i believe that beside the best moves, there exist interesting ideas,
that can be realized if someone is interested in.

this is what differenciates computerchess and human-chess.

computerchess is often not creative. the programs do not follow an idea.
they only compute the best move.

they are not interested in ideas.
they play chess like it is an EPD file they solve.
