Men talk in the office, or at home, or in the car when waiting in the rush hour. They exchange ciphers, one says „d4“ and the other answers „Qxd4“. Suddenly they smile or shout, or become silent.
Women beside do not understand what is that all about. Maybe some of them know that two men play chess in the air because they exchange the chess ciphers, they move rooks and bishops, knihts and queens, they eat each other, kill each other and win each other, win themselves and win the women' attention.
People are the play beings.
Sometimes one can think that chess men are dexters.
