Recent conflict between two players played on rapid (OTB) tournament, together with certain other doubts gave me some motive to write an article on 'Illegal move rule' which has been normally applied in rapid and blitz games. Let us go from very basics...

1st day of Chess Olympiad has been completed without surprises, all the favourites won their matches. Following are selection from most exciting positions today.

The following position is from one of recently played online games (15 min). Both sides were developing attacks on different sides of board...
