Membership vs Ads
Speaking of premium benefits, it would be worth paying to have additional Kings on the board so that just in case one gets traped, you let it die and continue playing with the spare King(s).
Some years ago in the first round of a Swiss tournament the guy beside me was scheduled to play NSW State Champion Pal Dozsa who was running late. When Dozsa arrived he told his opponent, "You can't win."
Well, the young guy, who had black, didn't know what to say. He thought it was gamesmanship on Dozsa's part, and spluttered something like, "Maybe not, but I'm going to try."
"It won't do you any good," said Dozsa. "I have no king. How are you going to mate me?"
So your option of extra kings would have been very welcome that day, Crazy.
I like Ads, especially if they are relevant. May be able to buy some interesting stuff...
