Don't make LUCK real
In spite of my prior sarcastic post, I do believe luck plays a factor in your poker winnings, but not in the way the way most people view luck.
If you have been beat up and bent over the poker table, as happens to everyone sooner or later, you look like a loser if you whine about it. If your posture, gestures, and whining make you look like you are riding on the tilt-a-whirl, players are going to target you as easy money. At that point, you are probably not making the best poker decisions, but even if you are, the other players won't believe it as you keep insisting you are the unluckiest player in the world.
After a bad beat, you just re-bought for 200BB, the table max. You have AA and know you are an 80/20 fave against everything. You are already counting the chips you're going to win. But what happens when you look like a loser on tilt?
You get AA UTG. You are tired of getting sucked out so you open for 3X the table norm at 15 BB hoping everyone folds or you isolate. But now you look desperate; everyone knows you're unlucky; you're still going to get lots of callers.
Players will call you down just to have fun busting you again. UTG+2 only calls with KK because he's thinking he is trapping you, he thinks he's made a good poker decision and doesn't want to risk a raise that will fold you out when he is thinking he is an 80/20 fave. MP1 with T9s correctly calls because he will be getting 20%
odds vs 2 players. Then LJ calls with 33 because he's getting good
pot odds at 10% vs 3 players. Now the CO calls with a 10% hand of 65o, because he can't resist getting a piece of the action. The CO is thinking any flop with low cards is golden for him. The button peaks at 72s and realizes that as bad as that hand is, he is still getting roughly 10% odds so he calls too, thinking it will be the funniest thing in the world if he takes a huge pot down.
While all these people have made reasonably good poker decisions, your 80% odds have fallen to about 35%. You're probably going to lose this hand because everyone is gunning for a big chunk of the bad luck loser's bankroll.
On the flop, there's a 90% chance all you will have is top pair with 5 players yet to act. The board will look like it had to hit one or more players. What are you going to do? Lead out a 90BB pot sized raise, half your stack, in desperation knowing you're probably beat even though you DESERVE to win this hand because you have the best starters. Isn't this proof you're the unluckiest player in the world?
How would that hand have played different if you looked like a winner? You would have opened for the table norm of 5BB. The KK would have raised you to 15 or 20BB so that he could isolate Mr. Unlucky Loser. No matter if the other players called or folded, when it got back to you, you would have 4 bet. Maybe the KK would have 5bet you all in at that point or would have at least called your 80- 100BB bet. Heck, he would have called your all in. You might have gotten your 80/20 preflop action for your entire stack. What could be better?
So how do you not look like a loser? Quit whining. Quit pounding the table. Change your posture. Take a walk making a lap or two around the parking lot until you calm down. Go home. Change tables. Posture is a big thing. Slumped shoulders, pouting lips, crossed arms. Private coaches in golf, tennis, baseball, basketball, and other sports often tackle a player's posture first. That's what your opponent sees and
tells volumes about your attitude and preparation.
A lot of players fall back to a super tight strategy when they are having "bad luck," but it will take several orbits of no play by you before the other players believe you have gotten your head on straight. If this game is in a casino and no one knows anyone else, expect at least one guy to give you verbal jab or two because the last thing he wants is for you to calm down and gather your wits.
If you can't accept that it is the nature of cards that you will sometimes lose several 80/20 hands in a row, then you might not be cut out for poker. It happens. Get used to it. Or come play on my table so that I can win your chips while you whine.
