chess or poker

[Shandrax]

You can trust me that Fischer could play blindfold easily. You will not find a single GM nor IM on earth who can't. With Fide Masters it is not guaranteed. There are 6 of them in my team and one of them is unable to visualize the board blindfold. So much for stats.

Besides that people tend to overestimate the tactical genius in chess. You don't have to play like Morphy or Tal to win. Chess can also be played successfully in a rather dry technical way based on a set of positional rules. If you simply make enough "plus-exchanges", you should be able to grind out a win. Needless to say, that's the style I prefer to use myself. My idols are Capablanca, Rubinstein and Botvinnik.
