Some great answers in this thread!! However, some of the more recent answers like these....
....are only good SOUNDING answers. In reality, these 3 players just haven't played enough poker to have seen the kinds of things most of us have indeed seen.
It is not only possible to win a large field MTT (600 or more players) with pure luck alone, it is actually probable.
Here are some examples of what I've seen.
1) I got moved to a table in a large field MTT. The game was no-limit holdem. I soon began to notice one of the players going all in every hand...(not ALMOST every hand, but EVERY SINGLE HAND). This player not only shoved when it was her turn to act, but she also CALLED other players' shoves (100% of the time). Here's the seemingly impossible part. SHE WON EVERY SINGLE HAND. About 10 of those times she needed a certain card on the rvier ( a 2 outer, 3 outer, sometimes a 9 outer etc) to win and bust the other player and ALL 10 TIMES she caught exactly the card she needed to catch despite the mathematical improbability of doing so).. now here's the ironic part. She DID NOT win the tournament. While heads-up, she had her very first loss out of the last 50 hands or so. This loss came after she shoved with AA, got called by garbage, and the garbage hand sucked out on her. 1 or 2 hands after that she busted in 2nd place. Although she didn't win the tourney, she absolutely demonstrated that it's possible to win with pure luck alone.
2) I have been playing the Mo Mo Mo PLO freerolls of late on the WPN. In every one of them that I play in and make it deep (top 20 remaining out of 500 or so), there is ALWAYS someone on my table who plays EVERY SINGLE HAND, sometimes the player will call, sometimes raise preflop but in 100% of the instances that player will open with any 4 cards and that player will WIN 100% OF THE HANDS and that player will occasionally go all the way to first place, winning the tournament by playing every single hand from start to finish. It seems to me that this is almost a mathematical impossibility, yet I've seen it happen, and the oddest part of it is that it happens OVER AND OVER AND OVER AGAIN.
So...the conclusive answer is YES, it's possible to win an MTT (even in large field events) with pure luck alone.
just the fact that you assume that I and the other 3 people "haven't played enough poker" shows that you base your facts on assumptions. therefor I am inclined to think you are obviously for one, exaggerating the absolute max out of the first situation you stated. do you know the mathematics you are talking about? for her to shove and call a shove every hand for 50 hands straight and win every time? that is like you rolling a dice 50 times, against multiple people, and you picking the right number 50 times in a row.
Get real.
You simply just negated every comment you made so I am going to show it no merit.
As for your second statement. Don't even get me started. I will make three comments on that statement.
1. momomo freeroll.....
2. you play regularly in tournaments that take 6 hrs to reach top 20 for 10$ price pool and yet you are boasting your experience over others
3. first smart thing you said "mathematically impossible" but you negated the intelligence of the statement by saying "seems" prior to, and by saying happens again and again and again, subsequently.
....don't bother trying to start a debate/argument please. I won't bite into it.
You see, in poker people like to make up these amazing and "CRAZY" stories...but man I gotta say, you just won a gold star for the crazy story award.
I can't believe how many people are here saying that you can win a tournament on luck alone. are you serious? you believe someone could sit down for their first time at a poker table with no previous skill and win a mtt?
If you say yes I really believe you need to re access the way you approach the game. In the case of people saying you can win simply by luck, I feel as though that is almost for self comfort. As tho you can sit back anytime you lose a tournament and say, oh well, the luck didn't roll my way. Or awww man, that guy got lucky.
I hear that way too often in poker. You know you do too, and it annoys the shit outta you. You win a big hand and what do your opponents say? YOU GOT LUCKY OMG OMG WTF WTF SO LUCKY!! YOU SUCK!! YOU HAVE NO SKILL!! JUST LUCK!!!
Come on people. Poker is 80% skill 20% luck. Why do you think pros STAY pros????? That phil ivey quote someone brought up about poker being the only game his sister could beat him in was a JOKE. Maybe in a single hand if she got EXTREMELY lucky. But could she win a MTT vs phily ivey or any other pro? where there are hundreds if not thousands of hands played?
