I want to know whether I understood these concepts correctly.
Complication: I think, in a given position, usually the side that is slightly inferior tries to make moves that somehow put considerable strain on the better side about which action to choose. Thus it tests one's ability to clearly calculate the labyrinth of all possible variations. Generally the lesser mortal fails and hence passes on the edge to the side that created such complication.
Simplification: I presume simplification is the reverse of it. By simplification I mean reducing number of pieces while maintaining the winning edge. I suspect the general idea behind simplification is to prevent any counter-play by the opponent. I guess the side with winning advantage always tries to simplify matters while the other side indulges in complicating.
Is it correct?
