How do I import a game from an email?

You import a game by first using the "Copy" function.

In the Mail app, open the email. Hold your finger on the email's body (the part that contains the text of the game) until the device shows a magnifying glass. Lift your finger. Touch "Select all", then "Copy".

It also works in Safari (in this case you can copy a game from a web site), and even in iBooks. It works in any app where you can select text and use the "Copy" function.

Now go back to the CHESS app and use:
Game > Load or import game > Import from clipboard

Please note that it will only work if your email contains a game in PGN format. Here is how a game in PGN look like and you can actually import this one if you want:

[Event "Alabama "]
[Site "Alabama"]
[Date "1855.??.??"]
[Round "?"]
[White "Morphy, Paul C"]
[Black "Maurian, Charles Amedee"]
[Result "0-1"]
[ECO "C33"]
[EventDate "1855.??.??"]

1.e4 e5 2.f4 exf4 3.Bc4 Qh4+ 4.Kf1 b5
5.Bd5 Nc6 6.Nf3 Qh5 7.d4 Nf6 8.Bb3
9.Qe2 Nxd4 10.Nxd4 b4 11.Qxa6 Qd1+
12.Kf2 Ng4# 0-1

WARNING: the lines between brackets are important. You cannot import a game if you do not have these lines (i.e. a list of moves is not enough).

In order to import the above game for example, you must select either the whole page (it will work), or the game, starting at the first "[" and up to "0-1".
