QQTT vs QQT2

What is the difference between QQTT and QQT2? The latter got me knocked out of the Pot-Limit Omaha Tourney at "The Shop". The tourney was a 70 bone buy-in deal that ended up with 17 players that played for 1st 600 bones, 2nd 390 bones, and 3rd 200 bones. Of course, I ended up in third. In any case, the QQTT was a huge pot early in the tournament that ended up with the whole table calling a 350 TC raise. I flopped top set and there was a club draw and some type of gut shot possiblility out there. Anyway, Pop's bet pot and I repotted, and planted some tomato vines, quickly. Pops thought about it and decideed his fluuuuusheeeee draw and gut shot were possible money against my obvious set of ladies. So all the money was in and the turn card paired 6's giving me the pot. That gave me a ton of chips and the possibilty to coast right through the tourney. as the game went on I did not catch many hands but did get into a big pot with Lance somewhere mid tourney. The board had J9X on it . I was first to act and the initial man who raised was next to me. I put him on Aces and I had flopped top two. So I bet pot and it folded to Lance and he called. The next card was a blank so I had to push all in with what was possibly the best hand or to buy the pot with a second best hand and hope that he had nothing or a hand that he could fold. Thank God, he folded because I was sweating bullets there. I am alwayse sweating in Omaha. So to my last hand. The game was three handed and I was UTG with QQT2, and short handed, short stacked this is a raising hand. In fact, I would raise with it with a gallon and a half of chips in front of me. I don't like the dangler, but I know this is a very good hand three handed. I bet pot 10,500 as the blinds were 1500, 3000 and I had like 5000 left after the bet. Lance thought and called and I smoked in the last 5000 or so and he called before the flop. He had a nice rundown hand of T887 I believe. Again, a playable hand, to knock someone off and if you are big stack, why not go for it. Well, the 8 came off for the set and I was a cooked goose. I felt good to know I did get my money in with the best of it though. Just the way Omaha is and no hand a real favorite. In fact no hand is ever 4-1 pre-flop. I played as well as I could and the only fault I think I may have had was laying down a hand or two I should have not. But, I would rather save a bet in a tourney when I am not 90-100 % sure of what the other player has. So third place felt good in the sense that I have not done well in a tournament in a while. And I have to get that program Pop's uses, that is sweet.
