The Art of Castling

'Is castling all one move?' asked a player before we started one of the rounds of the UKCC last week.

I confirmed that it was.

The games started and up went another hand. 'He's making loads of moves at once!'

The game had started 1 e3 and then Black had played 1 ...e5, ...Nf6, ...Bc5 and ...0-0 all at once. I asked him why and he replied: 'You said castling was all one move!'
