In the old notation system each square is given a name according to the piece that sits there when the game begins. The number depends on whether it is white or black who moves a piece there. For example, square D3 in modern notation is in the old notation system Q3 from white's perspective, but if black moves something in that square it is marked as Q6 square.
That's definitely a little confusing way to notate, but you get used to it after a while... hopefully :)
I am confused by the notation in Pachman's Complete Chess Strategy (1). I've heard several good things about the book, and would love to read it. The problem is that I can't understand the notation at all!
Here's an example:
1 PK-4 P-K4 2 N-KB3 N-QB3 3 B-B4 N-B3
I'm very accustomed to the notation used in the PGN format, but I have trouble understanding whatever notation Pachman was using. So far, my attempt at translation is:
1. e4 e5 2. Nf3 Nc6 3 Bc4, after which I am lost. I don't understand what half of the B's are for, and my mind is boggled by the strange numbering. Help! Thanks in advance.
