Yes, this sounds logical. But my data consists of the "usual" computer
tournaments, matches etc. witch were published in those years - and you see, the
opposite is true: We have *more* db endgames, not less. I think there are still
many games, where only one side uses tbs, and/or the loosing side just doesn't
resign (or doesn't agree a draw until the 50 move rule is applied).

I think Bruce is correct with his assumption (or conclusion) below.
