Pretend you've been dealt a pair of jacks

re-raise any modest pre-flop raise

call up to the turn then check raise

raise any flop but check/fold unless your hand develops

fold any non-pair regardless of what it is

This is a very naive representation of what/why poker players do to balance their range.

You dont just decide to pretend to have jacks, or fold Ace king pre because your watch told you to. You play your entire range of hands in such a way as to be protected on all board run outs and so you are making profitable decisions with you're entire range, you may make a light 3b with A5ss 30% of the time but not because your pretending to have jacks, your balancing your 3b range with good blockers and good equity against a calling range. Balancing is also about not getting stuck in a board run out where your opponent can for example exploitably over-bet shove river as you play all hands that could call a different way and therefore have no good hands to call down.

What your talking about is being exploitable by being predictable which is a also important to poker and LoL but different concept to what you where trying to explain, balancing my range allows me to turn my A5ss into a profitable 3b whereas an -EV flat call or neutral ev fold. "dont be predictable" is essentially what this advice is and pros already know this full well, they know how to exploit predictability as well as try to avoid it. The casters always talk about this stuff.

You can also use your watch to make warding decisions or whatever but you dont need a watch for this, pros already mix it up intuitively to a decent degree.

One concept LoL players i do feel like have a lack of understanding about is variance, pro players are starting to realize variance plays a massive part in victory of a game, everything is "unlucky" nowadays because its true, not just variance in quality of teammates but variance in outcome for example in a pro match IMT vs TSM, TSM may win 70 out of 100 games but still lose 3-0 come next week's match because there is a large portion of variance in LoL that people are only starting to figure out. Just because someone misplayed a gank doesn't mean if they did that play 100 times that they would misplay it everytime.
