The quickest method is to logon to your RPi and enter cd /opt/picochess and then cat games.pgn
You can also logon to your RPi by setting up an SSH connection. On Windows you can do this with a program called PuTTY, on Mac you open a Terminal window, on iPad you can use the app Serverauditor.
You need the IP address or network name of your RPi : Type hostname -I (capital I for India)
(probably something like 192.168.2.4 or "raspberrypi.local" or "raspberrypi.home") as well as the login and password of the RPi ("pi"/"raspberry" or "pi"/"picochess" if you already changed the password).
But the best way is to get your RPi to email your game:
Logon to your RPi and enter cd opt/picochess then sudo nano picochess.ini and remove the '# ' (hash and space) from the following lines, where xxxxxxxx is your gmail I'd and yyyyyyyy your password
enable-internet = True
pgn-file = games..pgn
email = xxxx...@gmail.com
smtp-server = smtp.gmail.com
smtp-user = xxxxxxxx
smtp-pass = yyyyyyyy
smtp-encryption = True
Hit CTRL X, type y & then enter, reboot and enjoy ....
