If we look at the games we can find tactical mistakes of deep thought that
the top programs of today have no problem to avoid.

One example is that deep thought let judit polgar to draw because deep thought
did not detect repetitions in the last plies and there are more examples.

I do not know about impressive moves of deep thought from games that the top
programs of today have problems to find.

I also believe that humans today know better than they knew at the time of deep
thought so comparing rating is not convincing.

It is more interesting to compare moves and I know of no impressive move from
deep thought from games(there are moves that the programs of 1990-1995 on the
hardware of 1990-1995 could not find but the programs of today on the hardware
of today are clearly better).
