Congratulations - you really do channel Lucius's dark soul. I honestly do like him more with Ron than Harry. Ron and Lucius both want to be chess masters - Ron knows the game better. He was born to it.
I know Lucius will do whatever he wants to do, but I feel like Ron has a better chance of engineering a trap, forcing a play, blind-siding him with passion like a freight train. Harry can use his "pure virgin innocent" power of seduction on him, but I see boredom creeping into that pairing. (I'm projecting - I'm bored with Harry's hero-ness. Weasley is my king and I want to romp with him.)
