Against a human, I think it's probably good advice. You would have to choose
wiesely when to use the gambits of course, but it would be a nice wild card to
hold.

Against computers I don't think it's such a good idea. Note that I am thinking
of gambits and sacrifices as different things here. For instance, it is well
known that humans can sometimes sacrifice and weaken the king's defenses and
execute a successful mating attack. Unless you are threatening mate, I don't
think a gambit will work well. For instance, threatening to sacrifice a pawn or
two for increased development isn't so great against a computer. Against a human
you can likely build up some significant pressure and it is likely, especially
against a weaker opponenent, that your opponent will crack and make one
miscalculation under the pressure, and you go on to win. Against a computer
there are zero miscalculations unless it is simply beyond the search depth of
the computer. That's why mating sacrifices and attacks work against computers
sometimes. They don't see the potential threat of mate because it may still be
many, many moves away after you've chased the king all over the board.

One thing to keep in mind is that a computer only has to find that one saving
line. If you have increased development/mobility/space/whatever, and the
computer can find one line to "hang in there" long enough to get it's pieces
developed, then you're down a pawn or two and have little to show for it.

I'm not that strong of a player though, so take what I say with a grain of salt.
I only know what I've seen from other players who have played computers (both
successfully and unsuccessfully).
