I think you're describing a 'barbers chair'. It's supposed to be one of the deadliest mishaps when felling trees; or at least carries the greatest potential for death. I've never seen it or had it happen to me but I've dropped more than one tree that landed approximately 90 degrees from where I had planned. I learned to use wedges and that increased my safety and accuracy. Still, the older I get the less and less I want to mess around with precarious trees. Once they're on the ground though, I turn into Paul Bunyun.I've seen trees with an obvious lean in one direction, start falling that way, then actually turn and start falling another direction.
