I was using "weaker" as "easier to beat". I'm not sure adding aggressive behavior is a way to weaken the engine, unless the aggressiveness is so over- tuned that it changes from aggressive to reckless and beyond. And the difference between the two might be significant. IE once it starts sacrificing a rook for a piece or a piece for a pawn, just to expose the king to an attack that won't succeed, it can become pretty easy to beat. My old super-constellation fell into that category in many positions. It became easy to beat it by giving it a chance to play (say) Bxh7+ and then taking the piece advantage to a win... The first few times, it might succeed, but then it just looks foolish.
