It is "my" thread so I should be no wimp and at least try to jump in :)
Second impressions ? Nah , still first ..
Game 3 and 4 of a new program . Shredder 5 on PII300 , now new opponent Gambit
Tiger 1.0 on PIII500 , Time control Game in 1 hour , 10 secs increment/move .
Some observations :
a.) Tiger's branching factor is _way_ superior at low depth ( sth not true
compaired to Hiarcs btw , answer to something else just read )
b.) Shredder's branching factor is quite significantly better at high depths (
at least so it seems )
c.) Tiger usually finds its good moves fast ( few changes with higher depth )
d.) Shredder _very_ often changed its mind at last ply before playing out ;
several main lines at low depths looked seriously weak ; several clever moves
found just in time .
All this _might_ indicate Gambit Tiger to be a better program at faster time
controls in comparison , yet 4 games of Shredder it is I have seen ( lol ) ..
Shredder has _very_ low NPS on a PII300 , sth like 50-80 NPS , more interesting
looks the time for a certain depth to be completed ; this is Tiger's domain ,
but Shredder is close , should be a very little tree Shredder has to search ,
and in the endgame Shredder is _fast_ .
1st game Shredder is my hero as it looked _so_ lost and nearly escaped ; again (
for the 3rd time in 3 games now ) Shredder sacs pawn for positional reasons to
get counterplay and it is _very_ close indeed ; still Gambit Tiger shows
superior evalutation in endgame and wins coolly .

Second game is way over my head ; it is one for the Turing test I think ; I am
just as puzzled like when watching the GMs fight it out ; thrilling quiet game .
One serious obvious mistake 27. ...Bd3 ?, but for the rest it's more like watch
and enjoy :
