I don't know on rigged.
What I will say is the Random Card Generators seem to cycle a program that repeats in a short period of time. But not the cards, more in players. What I mean is this.
I play 2 tables at a time. More often than not tourneys that start at same time or 30min later or 1hour later. Pay attention to those two tables open and it gets so weird to me how I'll run bad, bad, bad
hands dealt for 15 to 20min time in a row. Then boom at the same moment, hand being dealt I'll have PPs that are occasionally even the same for both tables. (88 or 77)
Seeing KQ KJ simultaneously both suited.
I've also noticed a sorta trap series of scenarios occur so often. Win a couple hands, sitting pretty. Fold the next hand seeing an allin. That player loses, Next hand he goes allin and I look down to a small PP or A10 suited most often or not. Since this guy is allin more often than not there's a call and I see the hand end if I didn't call. But this is what happens. If I'm calling this player always has better A JQK and wins on draw out. Never hitting. Or I fold I see the bad matchup I just avoided and sure enough if I played I'd have lost.
Another thing I run in to is any open straight draw I play Never gets there. It's like the software has a 0% guaranteed outcome on the open end straight hitting. But if I happen to be Allin on like a KJ Q10 ten and am gutshot come turn, I seem to hit this straight or my opponents especially. Gut Shots hit far far too often vs Open ended.
Try it sometime. Play 2 tourneys at once and watch how similar certain sequences play out. Both tables being dealt a good hand at same time when neither had a playable dealt in 5-7 hands. How often when playing an open end straight draw do you hit?
How about when you're chip leader at the table and in a matter of 3 hands you are bad beat calling a small allin with a good starting hand?
So I think the scenarios are rigged by the card generators. BB short stack getting a top 20 shove it all in hand facing the table chip leader who raised you all in and happens to have either the higher kicker, higher PP, or the lower kicker and sucks out on the turn...it has to always be the turn.
Sometimes I feel I can tell what is about to happen and make preflop folds that I normally wouldn't fold on that feeling and see a hand play out and I was right to fold because how the board went and I'd have lost the better starting hand or knew that short stack was about to be dealt a monster hand. Or chip leader was going to be dealt a better hand.
