FD, i don´t agree with how did you put him on low pair or bluff. When you try to put your opponent into a range of hands, you don´t have to committe the mistake of thinking that your opponent would play the same way you would do it. You eliminated AA,KK,QQ from the range of hands because according to YOU it´s wrong to raise 6xBB with those hands. You said that you don´t want to show too much strength with those those hands, but what if he thinks different? I think it´s a mistake to believe that it exists a general betting pattern that applies for all opponents. A 6xBB may mean something different to player A and to player B.
A 6xBB raise like that could mean something like JJ. In fact generally a big raise means a pocket pair like 10s or Js, because the player wants to take the pot right there and don´t want to see higher face cards at the board. But putting my opponent into those hands would still be a mistake, because every player have different betting patterns, there isn´t any collective betting pattern that applies to every player, althought there are some common sense patterns.
Those common sense patterns tell me that he doesn´t want to see the flop, so he could be holding a pocket pair (JJ or lower). I also would add two face cards.
To put him on a hand you must use your read on that player (preflop patterns are crucial). Everybody thinks different, so i repeat: to put him on a range of hands the best thing you can do is to use the previous information you got about him.
Now this is a MTT, and for some circumstances you may not have gotten yet the information you need (or you forgot taking the respective notes), so you must be very careful at the moment of making a decision. Without that information the range of hands becomes wider, so as a consecuence you must be ready to face a difficult decision here and a more difficult decision at the flop (if you decide to call).
Now having a range of hands that takes from pocket pairs up to JJ and two overcards, you must do a decision.
Fold, call or push? In my opinion calling is the worst play. With the range of hands we put him if you call he´s first to act at the flop and he would probably push in the flop regardless what it comes (either with a monster or representing something big with a continuation bet). You´re hoping just for a 5 or you´re going to be in trouble. If low cards comes, he may have an overpair, and if high cards comes, he may have an overpair. Definitely don´t call.
Now push or fold? You have 3000 with 50/100 blinds: a decent stack. If you push, you´re willing to make him fold or at least be against two overcards (if he calls it´s almost 100% sure that you´re going to be either a small favourite or a huge underdog). Given the circumstances you don´t need to take a race at this point (with those blinds i imagine it´s still early in the tourney). And remember that you´re hoping at best that he has just two overcards.
I fold. At this stage of a tournament i prefer making big decisions (like the push) with more information. If i have to put him on a wide range of hands like that, i prefer laying down and waiting for a better situation.
ps: FD, for the same reason you put him on a bluff i can put him on a medium pocket pair.
