GW-KW, Point Count Chess,Raw Discussion, May 19th 2011,What I Needed Ken To Clarify,[+] Pawn on 4th v Pawn on 3rd

May 19th 2011, additions to that discussion ...

Referring to paragraph 3 of Ken's comments, May 18th, regarding Pawn on 4th v Pawn on 3rd ...

(KW, May 18th) In #12, if Black moves the d6 pawn a second time to d5, he is down a tempo, and thus will be at a disadvantage. You would not count the tempo advantage for White at this stage, because it hasn't been realized, but you know if Black moves, he will be behind in development by one tempo, so you count that as the point now (4 v. 3). When he makes the move d5, you no longer have the 4 v. 3 point, but you have gained the tempo point. So one point converts to the other. Tempo refers to how many times each pawn or piece moves, especially in the opening. It is an advantage because it hinders the side on the 3rd rank.

(GW, May 19th) hence why many follow 1. e4 with 1. ... e5, or 1. d4 with 1. ... d5, respectively?

That's right. Either that, or a move with the Knights are the most common opening move for Black, (e.g., 1 d4 Nf6). Since you are moving a piece once, instead of a pawn, you are not behind in tempo.

Referring to paragraph 5 of Ken's comments, May 18th, regarding Pawn on 4th v Pawn on 3rd ...

(KW, May 18th) To sum up, 4 v. 3 means the opposing pawn must be on an adjacent file, and must be on the 3rd rank (not second), and the single square to the diagonal of the pawn on 4th, ahead of the pawn on 3rd, must be COA Center Dominated. If all three of these criteria are met, count yourself a point for 4 v. 3. If you reread p. 25 and 26 with this in mind, I believe it will make more sense.

(GW, May 19th) "In 4 v. 3, opposing Pawns must be on adjacent files". Gotcha! I'd been assuming they were on the same file. Ken, what you've clarified makes much more sense.

I understand this better, now. However, like with the others sections it'd be good if we could compile a small selection of examples to test understanding.
