In the hands of (White) player who
knows how to play it you can really have a hard time as black if you
don't know what the heck you are doing.

Right you are! IMO Black must be ready to play sharply, and be very alert
for chances of counterplay, but I guess that's true of many Sicilian lines.
A good resource for the Keres Attack is "Easy Guide to the Sicilian
Scheveningen" by Steffen Pederson. Another excellent book on the
Scheveningen is "Sicilian: ...e6 and ...d6 Systems" by Kasparov & Nikitin.
Although it's a little dated (published 1983) they do a very good job of
explaining the ideas behind the Scheveningen. If you do get this book, read
the comments with a critical eye, though, as it seems Kaspy doesn't give up
his secrets easily, for example....

In the Keres Attack, after the following moves

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.g4 h6 7.h4 Nc6
8.Rg1 *

Kasparov/Nikitin comment "An advance of the Kingside pawn chain with 8...h5
does not, in our opinion, solve Black's opening problems. White retains a
spatial advantage and the initiative..."

Yet the very next year, in game 1 of the first Karpov-Kasparov match,
Kasparov plays 8...h5.
