Beacuse to simplify in genearl is simply wrong: one needs to reduce the number of pieces if he knows that what he has in terms of advantage is winning, if not, you better keep more material on the board. Actually usually if you have a cramped position it is better for the weak part to simplify, to get some "air" (in italian we say "liquidate to a simpler position"). Of course if you have a queen up it's easy to say that simplyfy should mean a quick win, but if you have a piece or an exchnge it is far from obvious you will win. Then one should also know what to trade: if you have R+B+N+n*pawns vs R+B+B+(n-1)*pawns and you can chose which (color of) B to trade for you N you would have to know that with R+B sometimes opposite color bishops favours the side with extra pawn cause you can "attack more", while in the same situation with no Rs you would want to keep on the board Bs of the same color. You need to code a lot of chess knoweledeg, or you end up drawing some won games. On the other side I have the impression the computer programs often have a limited capability in using exchanse to "liquidate" to a position simpler to hold.
