The poster was obviously referring to peaking too early as far as the AO goes.
And that's what I was saying also.
If winning a 250 tournament with a rather a weak field is considered "peaking too early for AO", then he should give up his ambition to be a really great player. He is 20 yo FFS, and he is being touted as the next RF.
Hell, even players like Tipsy and Ferrer also won pre-AO tournaments.
