no seems ok but cant know for sure without stack sizes. given 2 limpers you might go for a check/raise on the flop here as players often limp with ace/rag type hands. but leading here isn't bad either it's good to mix up your play imo. after the turn i don't think your ever ahead either someone got the ace or a higher 2 pair than you. had you gone for the check/raise it's likely you'd of played for stacks as rep-x had top pair and a flush draw on the flop.

Without kowing stack sizes and revelant player history, it's hard to speculate too much, but IMO with blinds that high it's not usually a good idea to limp in mp with low suited connectors. Granted, you did hit your two-pair flop, but just calling the bet does nothing to help you narrow your opponents range in the hand, and as said in the post above me many players like to limp A-rag hands early and your two pair could be beaten by aces-up.

So to answer your question consicely: Yes, you did sdomething wrong by limping 34suited in mp at that stage (I'm assuming it's late) in the tourney.

Those hands should (usually) only be played in the first few levels, and in late position. Later in the game they have a habit of just costing you chips, as it did here.

You made a smart play, but i would like know your stack size, which would help out a lot.

no nothing wrong...guy with an ace would call anything i think...he had a highest pair and very nice kicker...
so you had no luck on turn...
