I had a similar problem with a confrontation between the antagonist and the protagonist that I couldn't seem to write. So I skipped past it, wrote a couple filler chapters with other characters then came back -- and dodged the confrontation with a description of off-camera avoidance by the protagonist. It's cheating on the cliffhanger I set up but my beta-readers didn't seem to notice. :) This also establishes that the protagonist is smart enough not to do something stupid which ties into the next crisis.

So, I am well past that spot and was at another hang-up: how to motivate the protagonist to do something stupid when we've already established that this is one character who thinks things through. So again, I avoided writing the crucial scene by jumping to the side characters. Now I'm ready to come back to it and I know that the protagonist's motivation to do something stupid is the emotional crux of the whole story! Chewing the scenery is one of the things I do best so this won't be that hard to write. :)

Moral: Never write the hard parts until you are ready to do so. Because if it is hard to write, there's something you might not have thought of yet.
