Abstract
We investigate here the behavior of a few spherically symmetric static accl aimed black hole solutions in respect of tidal forces in the geodesic frame . It turns out that the forces diverge on the horizon of cold black holes ( CBH) while for ordinary ones, they do not. It is pointed out that Kruskal-l ike extensions do not render the CBH metrics nonsingular. We present a CBH that is available in the Brans-Dicke theory for which the tidal forces do n ot diverge on the horizon and in that sense it is a better one.
