That’s what I mean; there is no such tendency.
There’s no reason to say that the next hand dealt in a fair game is any more likely to go to the winner of the previous hand than it is to go to the loser.
People do think that way, because of how our brains are wired. If you see a thing keep happening, we’re evolutionarily programmed to expect that to continue to keep happening. We notice when things change.
When a player wins, and then wins again, and then wins again, we think the likely outcome the next time is that they will win still again. Yet, there’s nothing that makes that outcome any more likely than any of the other previous wins were, in terms of the cards.
In terms of the player, or in terms of the chips there’s where things might be going on.
The player who’s lost several hands in a row might start thinking “I just can’t catch a break” and start doing any number of things, from folding more to play a tighter range; overfolding marginal hands like middle pair; stop chasing draws since they “never” fill; overbetting hoping that the aggression will intimidate the other players and let them steal a hand; bluff into a made hand that isn’t going to fold. This may be called “momentum” but a better way to understand what is actually going on in this situation is that the losing player is playing poorly, or perhaps they played fine, but now has made bad adjustments which are further hurting them.
If you just chalk that up to “momentum” it doesn’t convey any of this understanding, and you’re left with a mystical sense that somehow the “hot” player is “on a roll” or is “playing good” when all that’s happened is they had a good outcome or several on a few hands that could have gone either way, and now his opponent is flummoxed and has lost faith in his “ability” to draw winning hands, and responds to this by making inadvisable adjustments to how they’re playing.
Players may be able to exploit the human nature of their opponents into making them believe they’re on a hot streak and can’t lose, and this can result in them over-folding. So, if you want to do that, one way to do it is to convince everyone that you’ve got this mystical force behind you called “momentum” which means that you can’t lose. If that works (convincing your opponents that there’s voodoo on yourside when there’s no voodoo) then good; you’ve got an edge in your game over your opponents. But Dumbo the elephant didn’t need the feather to fly, either.
Chips also can be used as you say as a kind of force, but that force isn’t best understood as “momentum”; it’s pressure. You win a hand, you stack an opponent, and double up. Now you’re the big stack. Suddenly, no one can knock you out; at worst all they can do is double up themselves to knock you down to even. Now, if you want to, you can raise bigger than anyone can afford to call, and push a lot of players off of reasonable, playable cards that just aren’t worth calling off 1/2 your stack preflop with, or going all-in on the river.
If you think of your big stack as being at the bottom of a slope, and all the chips at the table roll down the slope, and that the chip stack itself has a gravitational field, such that the larger it gets, the more the rest of the chips are attracted to that stack, you might think that what’s going on is a sort of momentum.
When really, the chips are just inert objects, and aren’t attracted to each other at all, and what’s actually going on is that you’re winning them by convincing your opponents to put chips in the middle when you’ve got the best hand, or to concede the chips they already put in the middle to you because you’ve convinced them that they ain’t got it. And one of the best ways to do the latter is by putting pressure on your opponent to fold by making bets that are comfortable for you with your big stack, but not comfortable for them.
But again, if you confuse yourself by thinking of it as “momentum” rather than “pressure”, you can convince yourself that your stack is “too big to fail” so you can bet anyone off any hand, because your betting is just that intimidating, and that’s when you try to bluff someone off a pocket overpair by betting a draw like it was a made hand, they call, double up, and now you let them back in the game.
People have that happen to them all the time and say, “The momentum changed!”
No, it didn’t, you overplayed your stack, got beat like you deserved, trying to use position and big bets to win hands, forgetting that people can call, and now your favorite weapon got taken from you, and what else did you have left to play with?
If nothing, then you’ll probably continue to lose, still won’t understand why, and chalk it up to mystical “momentum.” If you understand that you were winning a lot of hands due to the pressure your big stack was putting on the other players at the table, you can better appreciate the mechanic at play, and thus use it better to win those hands and to avoid blunders that can arise from being overconfident and as a result playing poorly due to a misunderstanding of what’s actually happening at the table.
