I think none of this useful advice will make OP change his mindset. Based on his approach to gambling, it seems that he already created and form a mindset that he has the ability to always win in gambling because of his winning experience.
Maybe we just have to allow the OP to do what he wants since, in fact, he really stands on his crappy beliefs.
Let him taste his own medicine. Good luck to the OP on his revenge mission.
He will listen to no one.
He's determined and has set his mind already and that's why whoever gives him good advice, he'll do the opposite and that's why everything that he's trying to do is his own act of his will.
Everyone will not be surprised if he comes back and tells a different story for where he has lost tons of his money.
