In Round 1, each player picks a letter and names an XI whose names all start with that letter. For simplicity's sake, we'll go by the name under which they're sorted by Cricinfo - so Imtiaz Ali, Ted a'Beckett, Abdul Qadir and Zafar Ansari are all valid 'A' picks but Wasim Akram and Andy Caddick are not.
In each later round, each player again picks a letter and picks 1 or more players starting with that letter. These players now become part of their XI, and they must also drop the same number of players they'd previously picked. Alternatively, if you're happy with your XI as it stands, you can pass. Once all players have passed, the draft ends.
You cannot pick a player who has previously been picked, even if they've been dropped, including players you've dropped yourself.
