PP. ..P ... R.. The a6 pawn cannot be considered isolated unless black plays ba (which is not forced). The reason that it appears that the a6 pawn is backwards is due to the white rook having control of the a5 square indirectly (since white can play ab at any time). If black had another rook protecting his a8 rook, then the a6 pawn would not be considered backwards due to the a6 pawn not being pinned (i.e. the a6 pawn could be pushed without the penalty of losing a pawn). I think that examples like this are excellent since they illustrate that some concepts are MUCH more complex than is readily apparent (and hence the need for a search engine). KarinsDad :)
