Would you? I find it usually just slows things down. A player would do something pretty creative, but by the enemy's standards I didn't tell them it really wouldn't work. I don't really want to just be like "Sorry he stabs you, you died.", do I? It creates a pretty big condundrum and slows down my response time.

And in RP's in the past I and other players have been pretty confounded by the GM's decisions, and I'm sure that I have confounded some of my players in the past before as well. This collaboration is a new thing I'm trying to see if I can avoid these issues. Because you'll still get surprised. I'm not going to tell you everything, but when it does show up my plan is tell you what you can do to get out scot-free, and you can decide what your character would do. (which is probably not get away with no issue.)
