Whenever I watch pro-level games, a thought comes to mind: the pros base so much of their strategy on the metagame that it would be really interesting to see them lose due to doing that. It'd be like if they play a slightly-lower level player, and go, "Well, six-pool never works, so nobody would try to six-pool, so I don't need to prepare to fight off a six-pool" and then get six-pooled to death.

I know it'd never happen, but it'd still be kinda fun to see once or twice.
