In NewInChess (the famous dutch magazine) there are often commentators that
report computer found tactical shots. Among the youngsters of course anybody
does (Morozevich, Van Wely, Leko, Kramnik, Anand....)

E.g. in the last issue Morozevich gives the following line found in a sideline
from a 'his electornic friend' (most probably Fritz):

Morozevich - Kasparov (Astana 2001)

[D] r3nrk1/2qb1ppp/p2ppP1B/4b3/1p2P1Q1/1BNR4/PPP3PP/5RK1 b - - 0 1

white has just played

18.f6!

and he explains that after 18...Bxf6 19.Rxf6 bxc3 white should play 20.Rxc3
and says that 20.Bxg7 does not work, because of the line (found with computer
aid) 20...Qxc5! 21.Kh1 h5

this 21....h5 is an example of strange move which a computer easely finds while,
humans hardly find over the board. Well any GM would find it there, they could
miss it from an earlier position.

Kasparov uses the computer as well (he likes Junior btw).

On the other side I never heard players like Timman to quote a computer found
move. And it is pretty well known that Karpov in an advanced chess match against
Anand was apparently not getting any benefit from the engine, and stopped using
it preferring his intuition, while under time pressure.
