Limping in with big PP in pstars deep stack tourneys

[Bandgeek]

I've seen alot of this and I'm wondering if there's a purpose to it or if the players are just donks/weak tight?

The two hands that busted me out of a recent tourney, two different players limped in with QQ and KK respectively.

Obviously when the flop came these two hands weren't in the range I put them on and I paid for it.

In these particular cases the trap worked, but most of what I've read says it's a very big mistake to let people see a cheap flop with a big PP.

Any insight you have into this will be appreciated.
