Subject: Computers Adjusting Play Style

How will computers be taught to adjust their playing style when facing weaker
opponents? Two examples come to mind, one recent and one older. Recently
the game of Fritz (rating: not yet established vs humans at 40/2) vs Hasidovski,
A. (rating: 2177) saw Fritz cheerfully swap down into a drawn endgame. The older
example that comes to mind is the Deep Thought vs Wchess draw.

This I think is not just a Fritz or Deep Thought behavior but common to most or
all programs. Chess games often follow quiet paths that make it difficult for a
tactically stronger player to utilize that advantage. What can programmers do to
compensate for their tactical wizards not knowing the opponent? Could having the
program receive input as to the players rating be of use? They might then play a
"second or third best move" but keep the position more alive with tactical
possibilities. Or will computers always play what they evaluate as the "best
move" regardless of opponent's strength?
