There are at least three well-known ways to "dumb down" a program: 1. reduce the search time (a time-handicap mode) to give the opponent more time. This has to be done in conjunction with disabling "think on opponent's time" or it won't work well. 2. reduce the positional scoring terms so that the program loses the significance of positional considerations. IE passed pawns become less valuable, open files become less important, pawn structure becomes less important, ditto for king safety, etc. 3. factor in some sort of random number so that positions that are bad will randomly look less bad or actually look good. Or, if the random addition is large enough, but infrequent enough, the program might begin to make tactical blunders (ICC has some *bach programs that do (or did)) this, and they would make an occasional blunder like a weaker human).
