The talk delivers insight into the calculations of highest order post-Newtonian (PN) Hamiltonians for binary black holes. The conservative dynamics is presented up to 4 PN order for binaries with both non-spinning and spinning components, where the spins are counted of 0.5 PN order. The related dissipative radiation reaction dynamics is known up to 4.5 PN order. As application, the Innermost Stable Circular Orbit for spinless binaries is given through 4 PN order and the test-body limit is compared with the exactly known ISCO of a test-body orbiting a Schwarzschild black hole.
