depending what your playing cash, mtt or turbo,
try and get a feel for your opponents, and get into the habit of going down streets.
betting patterns, board textures, calling range/and villains position from call/raise
The thing is if your getting it in with Ace jack suited your only getting called by very strong hands and losing value when good.
if your opponent has the set by controlling the pot you cut losses when good, and get your value / bluff catchers etc
also sets are pretty rare 7/8to 1 and pocket pairs are longer odds
, so you should be optimistic that this isn't going to become a -EV occurance
