Is the heads-up bug catching on...

I didn't play any more tonight but watched an instructional video as I thought it might be helpful. Well, since I get so much pleasure from playing post flop poker well, it is a natural migration to start playing these games I suppose. Overall since I'm going to read so many more flops per hour etc I'll become a good postflop player much more quickly. The video was done by a player called croixdawg who is an exceptional player. The skills that he demonstrated to me that need mastery are:
1. Hand Reading - pretty obvious really, but his commentary really demonstrated his knowledge of pot odds, implied odds, and opponents' likely range. Every reevaluation on each street used all of the information gained so far. I was suprised by the loose calls with things like overs and gutshots. But then while watching it seemed to make sense as he obv had a good plan of how to make up the steal equity that's obv required to make calling profitable.
2. Timing Tells - since he was playing a microstakes video he was using timing tells as a large part of (1.) - in other words using multiple street bet timing to help decipher hand ranges.
3. Bet sizing - He was bet sizing pretty transparently. In other words min raising marginals and 3x raising good hands. I suppose at these stakes that's good strategy and since this player is earning half a million dollars + each year I'm guessing he mixes it up a little at higher stakes.
In conclusion it's great to watch and listen to a true sick poker earner and his thought processes and game style. I think I should become a heads up player. The more I think about it the more it makes sense. One last point... In full ring games the best players blunt their edges over fish by playing their silly 3-bet games with each other... it shuts out alot of the profit. As well as this I guess the table profit is shared around - as I've said before. So while full ring games are prob still profitable, heads-up (at least in NLHE) looks by far like the best investment. Rant over, good night.
