If you dont play a strong game of otb chess now---forget about blindfold chess, it ant gonna happen. But, just for the sake of argument, lets say you are in the 1700's and you can play a complete game of blindfold chess (extremely doubtful) . At 1700 you're making many mistakes in sighted play and those mistakes will be multiplied in blindfold chess. Strong blindfold players play at a level several hundred points below their sighted elo. So, if you are 1700 and can play blindfold chess---then you are playing at the 1400 level. Who cares, who are you going to impress playing at a beginners level. Your little sister maybe?
Forget about it---get as strong as you can over the board. We should be talking about what were the great Blindfold feats in history. I vote for Pillsbury- Hanover- 1902.
This was during the great Hanover tournament during Pillsburys rest day.
His opposition was players from the minor tournament who were masters or near masters---some later became GMs. 20 something boards, made up of four players each. They could talk to each other, consult, move the pieces around---unbelievable exhibition! I dont know how Pillsbury won a single game under these conditions. It lasted well into the morning hours and Pillsbury had a game scheduled that very morning in the big tournament.
There are many other examples of great blindfold play---Reuben Fine playing blindfold chess, 10 seconds a move, with four strong players and winning every game. How does one play multiple games of blindfold chess at 10 seconds a move??? Now that I dont understand!
