  We discuss the "quantum deformed Schwarzschild spacetime" as originally
introduced by Kazakov and Solodukhin in 1993, and investigate the precise sense
in which it does and does not satisfy the desiderata for being a "regular black
hole". We shall carefully distinguish (i) regularity of the metric components,
(ii) regularity of the Christoffel components, and (iii) regularity of the
curvature. We shall then embed the Kazakov-Solodukhin spacetime in a more
general framework where these notions are clearly and cleanly separated.
Finally we analyze aspects of the classical physics of these "quantum deformed
Schwarzschild spacetimes". We shall discuss the surface gravity, the classical
energy conditions, null and timelike geodesics, and the appropriate variant of
Regge--Wheeler equation.
