Discussing games in progress with anyone with chess knowledge would
be unethical.
However, you can make use of as many chess books as you like,
which is the method open to all correspondence chess players at all
levels. Therefore, if you have a question about the opening of a
game in progress, you may refer to a book about that opening but
should not discuss it in the forum.
When I played a lot of correspondence chess in the 70’s and 80’s, I
often found myself without enough information on a particular
opening. As a result, my personal chess library grew by many
books.
