As anyone who has ever seen Ingmar Bergman's The Seventh Seal can attest, Death grants no pardons. He can, however, be forestalled for a time:
Sure, Death will eventually win--that's a bit of false modesty when he calls himself "quite a skillful player"--but a clever chess enthusiast like Antonius Block can buy himself a few precious hours, days or even weeks if he can manage to put together a solid game.
Clearly chess, a game of endless strategy, is the ideal way to postpone the inevitable. What few people know is that Death has been known to play many games. More than anything (aside from ushering you and me to our dooms) he likes a good challenge, even if he is confident in his superiority (he's also a devilshly good cheater). For those with no skill in Chess, the Grim Reaper will happily go head-to-head in any of the following:
Tic Tac Toe
Hungry, Hungry Hippos
Just remember, you don't have to be a chessmaster to hold off Death for a while, and the above list is certainly not comprehensive. He's not picky about the game he plays. Challenge him, and when he wins the first time, call it best two out of three.
