Subject: What do chessprograms know? Isolated pawns

Quote from "The Amateur's Mind" by Jeremy Silman:

"2nd negative - The formula to beat an isolated pawn calls for control of the
weak square in front of the pawn so it can't move, the trade of all minor pieces
(which ends all attacking chances for the owner of the isolated pawn), the
retention of a Queen (this stops the enemy King from taking part in the defense
of the pawn) and one or two rooks (which will be used to attack the pawn), the
doubling of these pieces against the pawn and the use of a friendly pawn to
attack the pinned isolated target"

I am curious which parts of this IMHO very convincing explanation are
implemented in chessprograms, especially the non-trivial ones:

Defender:

- wants to trade rooks, wants to trade queens, wants to keep minor pieces

Attacker:

- wants to keep at least one rook, keep the queens, trade all the minor pieces


Of course these are very much ceteris paribus rules, but I got the impression
that most strong chessprograms have no idea about any of this.

How about your engine?
