Compression drop snap and a pusher tree. or as Northman said back cut first on small Dia against the lean.
Also what I do on very small Dia is tip cut half my high side. once I'm deep enough to clear the back then I bore in, leaving a little strap then I cut to the hinge. I load up with a side wedge a bit, then cut the little tab out. Wedge where its best suited.
A couple issues with that cut is you are fighting a little more vertical holding wood.You may be limitating the ability to wedge from one side or put one on an unfavorable side. The sequence is important too as the saw can be caught in a bypass kerf.
That's how I cut large diameter forward lean. You're backward man.
