Are there popular games where the best human players are not near the limit of what is possible? Obviously you can construct one to be hard for humans (large 3SAT problems, or even big arithmetic problems), but I wonder if there is one that people enjoy.
I'd assume that for pretty much any nontrivial game the best human players are nowhere near the limit of what's possible. Humans can play a perfect tic-tac-toe, but for everything in the realm of go, chess, poker, bridge, etc the theoretical ideal is far beyond currently best human players.
