The Right Action in Poker

Look at the situation under the following angle: throughout your career you will have many pluses, as well as negative days. In ten years will not have the slightest value, you won or lost on a particular day. Much more important will be the total of all the wins and losses, that is, the net profit for 10 years of playing poker.
There are two ways to increase net profit, and you have to work in both directions:
You can increase your advantage by learning how to squeeze more money out of strong hands (this is where most players focus their efforts).
You can reduce your negative, showing discipline when the card does not go.
In my opinion, the second is easier to implement, while a loss reduction actually has the same value as an increase in winnings. As they say, the money saved is the same as what was earned.
Once you comprehend your goal – to make better decisions than to abstractly “win”, or get up from the table, being in the black, situations in which the card does not go will begin to acquire features of interesting opportunities.
Having discovered {A-} {A-} in the first position, I know that mathematics is on my side, but at the same time, I probably will have to make some difficult decisions. Even if I win the pot, it’s possible that I will play non-optimal. Was it worth playing limp-reraise or just opening a raise? If the second, then what size should this raise be? Do I bet on the flop or play a check raise? If the opponent calls, a similar dilemma on the turn awaits me. And if the rival makes a raise, what are my actions? Even with the nuts of the opportunity to make a mistake in bulk.
On the contrary, with the hand {9 -} {2-} offensive in the first position, everything is simple. All that is required of me is to look at the cards, throw them in the center of the table and congratulate myself on the work well done. Unlike the situation with pocket aces, I know that my game was perfect. The best player in the world could not have played better. I never lost sleep, dropping my hand two or nine pre-flop.
