Raw Discussion, May 19th 2011,
What I Needed Ken To Clarify,
Outside Passed Pawn
May 19th 2011, additions to that discussion ...
Referring to Ken's comments, May 18th, regarding the Outside Passed Pawn ...
(KW, May 19th) It doesn't need to be on the flanks. It just has to be the "passed pawn...most remote"(p.251) from all the rest of the pawns. If pawns are blockaded on g and h files, for instance, and Black has a passed pawn on the e file, and White has a passed pawn on the d file, the White d file pawn is the passed pawn most remote from all the other pawns. Thus it could be central, or on the flank.
(GW, May 19th)
Just to clarify, further, I've flipped the No. 176 (page 251) ... In Ex.1, above, even though both sides have a Passed Pawn, this time it'd be Black's a4 Pawn that's the Outside Passed Pawn
Ken's Comments ...
Right. Here if White eventually snatches up Black's a pawn, the idea is the Black can snatch the c pawn (through proper manuevering), and because he is closer to the other two pawns that are stationary, he can get there faster than White's King, so will get the White pawn on g4, and be able to nurture his Black pawn to Queening, thus the outside pawn is a major advantage in the endgame.
White must deal with this loose a pawn, but to do so will lose the game for him. He is lost already. If you were to go back, say, 10 moves in a game like this before the final exchanges, an Outside Passed Pawn is a countable point, and also lets you know that you should exchange everything to get to the position above, to win the game.
