PDN flagged[edit]
The PDN checker gives the following warnings about the examples given on this page:
Warning: on line 18 column 1: Invalid Date value "??" Warning: on line 23 column 1: Invalid tag: Setup must be spelled as SetUp Warning: on line 24 column 1: Invalid dot trailing a FEN value "W:W27,19,18,11,7,6,5:B28,26,25,20,17,10,9,4,3,2."
- The convention to use "??" for an unknown date value is inconsistent with PGN. - In chess a FEN value is not ended with a dot.
Furthermore one of the examples ends with '1/2-1/2 {a very popular position} 1/2-1/2'. This is probably a mistake, the PDN checker interprets the part '{a very popular position} 1/2-1/2' as a new game.
