The dog on b5 is in danger. Originally clueless was not able to solve this problem at postal speeds. It now takes around 45 seconds to come up with a move that saves the dog.

I think I've seen this pattern a few times in live games, where the quiescence has to generate captures including defensive steps in order to work correctly.
