I had a toothache during the first game. In the second game I had a headache. In the third game it was an attack of rheumatism. In the fourth game, I wasn't feeling well. And in the fifth game? Well, must one have to win every game?

If the defender is forced to give up the center, then every possible attack follows almost of itself.
