Sam need and codependency on dean ultimately caused him to give into Lucifer and he let him help find him and that opens the gate to more psychological torture.

I think the first step to letting Lucifer in was the "shut up" and then the slight working together solidified it.
Happy holidays!

I always assumed Sam's tricks don't work on Hallicufer anymore because Sam talked to him and asked for his help earlier in the episode.
