I wish I could go all-in ten times in the same tournament with a 60% hope of winning
ALL TEN. Why aren't you seeing that this is IDEAL?
How many tournaments? Sample size is paramount here.
It must be just you, because every poker player in the world wants to maximise their edge over the competition... except for you

Holding AA with an ace on the flop (your example) gives you top three of a kind at the least (full house possible too

). On the flop, that is more or less the nuts, even if flushes and straights are possible - do you see why?
Either way this is all opponent and situation dependent.
Just how it goes down I reckon. You may well be right but I seem to keep losing to the improbable noob fish all the time. Hell I even lost an allin to 27 last week.
From a quick check of stats I have the following:
High stake tourneys won: 7
High stake tourneys top 10: 38
Low stake tourneys won: 0
Low stake tourney top 10: 1
Bubble on high stakes 97/147
Bubble on low stakes 7/256
% chance of winning some money on high stakes: 66%

% chance of winning money on low stakes: 2.7%

% chance of winning a high stake touney: 4.7%

% chance of winning a low stake tourney: 0%
I don't know, I may not have played enough low stake/cheap satellite tourneys yet for the odds to come may way and I am just dam unlucky in them????
And as for the aces, I wasn't talking about somebody needing another card for a str8 or a flush, I meant that they might have the str8 or the flush as soon as the flop goes down. Okay, a lot depends on how many players saw the flop but it is reasonable to expect a good player who goes allin to have a better hand than you with you needing another ace or a fh to win it. I have in high stake tourneys on later tables laid down AA in this situation which has proven to be the right fold after seeing the other persons card. As to whether any of the 7 cards I needed to win came out, I would never know.
The best example of my "bad luck" vs noobs is the following from a game last month where I had played well to get myself steadily into the top 10 when this happened.
Me: 10k chips
Donkey 2k chips
I had AA, flop no danger from the flop, end up allin with the donkey who had 97 clubs with one club on the flop, he got the flush.
Next hand I had KK, no immediate danger from the flop again, he had j10 suited and he won with the str8
Next hand I had QQ, again no immediate danger from the flop (all lower than me Queens, no str8 or flush possible. End up allin with the donkey for the third hand running and he had 77 and pulled another 7 on the river. That was me out of the tourney.
Tell me, would you have folded any of those hands? I suspect not.
Worse than that was 3 hands later the donkey lost all his chips with another stupid allin to somebody else where the better hand held up.
