Limit poker is extremely disciplined at the higher levels. Most players do not have the skill set to beat high stakes limit poker games. Anyone who thinks limit poker is for pussies; go sit down with Jennifer Harmon and Johnny Chan and watch swings in the neighborhood of +/- $250,000. NLHE allows undisciplined players to occasionally show profit, these same players find that the luck variable does not repay them for all the poor play when they are playing against disciplined opponents.
