This is why it's called a "trouble" hand.
To put it simply, you called 6 times the Big Blind W Q-10? Thats MORE than 10% of your stack preflop, with Q-10! Even suited...plus, you pulled the trigger, I think, a little soon. Now, don't play scared, but instead play smart.
So, lets say you call...What are you looking for on the flop? Only a straight, a set or a flush, right? Many a straight you get could give someone with KQ, K-10, a bigger one. Any flush could give anyone with A-x or K-x a better flush. Any four card flush could get you killed by a bigger flush as well. Any A or K could give someone a bigger set (as it did). So, even if you call to see a flop, you are still in danger! Just pairing your Q would have lost to those Kings. Again, even 2 pair could lose to KK if a A and a J fall, or a J and a 9.
Also, If you get a dry flop with no aces or faces, what could you reasonably
bluff here to a guy with an over-pair? A set? Maybe if you re-raised him preflop you could bluff an ace, but in a merge freebe? Not likely. I've seen them call with QQ (another hand, BTW, that has you dominated) after a re-raise and an ace hits the flop!
What happened to you is classic...you got the "little" full, he got the "big" full.
Trouble hands are just that, unless shorthanded and/or suited. Even then, it's a risk better taken against a preflop limper and you raise from a later position. At least that way, you are in control. Out of position 6x call w Q-10 suited? I'd leave that one at home in any merge free roll.
