I once devised a way to lower the engine's playing strength by simulating a slow hardware.

What I did was to reduce the target search time, but still consume as much time.

For example, if the target search time is 10 seconds, search() is told to run for only 5 seconds, and then the xboard shell will sleep for the remaining 5 seconds before printing out the move.

The sleep is necessary so that the clock would wind down in the expected fashion.
