What are the typical stats for VPIP, PFR, 3bet etc. of a good TAG and a LAG in NL high-stakes heads up poker?
sharkscope.com lets you search for stats of some famous players, you can check it.
Dont try blindly to copy/achieve that stats, your play depends on your opponent tendencies, your goal is to have profit, therefore you have to consider your opponent tendencies to play. Heads Up especially is very "wild" and your decisions vary a lot depending on your opponent.
Also, if there is stat like "PFR = 50%", it does not mean, that the player plays the top 50% of hands. He can have like 30% from top hands and 20% hands from bottom range to balance his strong/weak ranges and confuse opponents.
Looking at other players stats is at best a waste of time and at worst a serious departure from NLhu study.
Whether your game is tighter or looser, more or less aggressive, studying the stats of others winners is of no consequence. Your game is your game. Don't ever forget that by vainly attempting to artificially adapting your game to someone else's, it simply does not work that way. Remember too, what Phil Ivey said about practice.
"There is no substitute. "
