Plunge Cut Ahead with Caution
You can come in with the bottom tip corner and trenchdown, then feed in pressing down as saw pulls itself along, not contacting ever the upper tip corner till buried into the sheath of the wood to jail it positively. So that the power of that upper corner can't whip the saw around, and the cut is made by the powerful captured tip's leveraged arc running from chainsaw power, feeding saw in automatically walking on bottom bar contact. As contact with the bottom of the bar draws operator/saw inward; so make deep enough cut that the top bar isn't contacted to push out of the cut. Highest torque is around tip corner's arc, the top half of that semicircle (bar tip) can be especially deadly if contacted in about any other fashion,than in this 'box'/jail. Kinda some strategic use, when other options are scarce i think. This is serious stuf with serious forces, no game, but doable! One of the extreme forces is heat build up in side the well insulated jail; so sharpest of chains, best of oiling, some letting it breathe with breaks if large cut, going quick, but easy , watching for the first whisp of smoke (to stop)etc. anything to strategize against heat build up.
The horizontal seperations in picture are fractures along the grain, so outside vertical cuts, must be close enough to the interior vertical plunge cut to allow the fracturing to seperate per pressure it bears. The pressure load casuing fracturing can be applied / triggered remotely as finish with proper force and direction, not necessarily constantly existing pressure, thus snapping/fracturing with saw operator clear.
