Curtains: pick off a PVS?

Yeah BB vs. having others to act behind is a big factor, so as always is whether the game is 33, 55, 215 ...

This post just caught my eye because I have bought quite a few pots with this move lately and had the thought that maybe I should be doing this with total trash sometimes. If they fold anyway it makes no difference right? This is from recent play in the 55's.

That said, of course they don't always all fold so pulling this with trash is dangerous and the move should come with a warning on the label - don't try this at home kids.
