What game and game conditions require the most talent? In other words, what game (stud, nl holdem, limit holdem, omaha, draw, etc.) and game conditions (sng tourney, multitable tourney, heads up, ring game, b and r, online, shorthanded, fullhanded, heads up, etc.) can be least played with a formulaic strategy and therefore difficult to teach, thus requiring talent and "cardsense"?

We know that 1-table SNGs and tournaments can be beat with formulas that would allow a newbie to not be too dominated by a pro. Razz, lo-ball, and jacks or better can also be beat with a near formulaic strategy. Therefore, these don't require much talent, just study and practice.

My guess is that the game and game conditions that requires the most talent (aka, is the least teachable) is very deep stack heads up no limit holdem played at brick and mortar with both players facing each other, with no dark glasses and walkmans allowed.
