hehe. not with neural networks, but your aggressive style of posting with the
judgement that I did not understand neural networks, which I did never pretend
BTW. So I accuse you of producing hot air. And then I show how you do it in many
other respects. Let's see in detail.

But you claimed it in CSS forum!

In your staement for CSS you said the contrary.

I will check this because I am not at home but then I will give a statement.

Objection! You want to say that it wasnt YOU who are responsible for the only
mentioning of TIGER as a chess program???

>But who cares about my personal background here???

Those who are astonished that you spring on the shoulders of a psychologist who
you declare as incompetent in neural networks although nobody pretended that he
was an expert. The topic was neural networks, but here the question was NOT
about neural networks but about chess, that was no longer addressed and which
therefore was the reason for my message BTW! Not because I am an expert in
neural networks.

And you yourself, what is your talent besides chess programming? See above.

Wrong. I jumped in a topic that was a psychological one, not about neural
networks. Buit if you insist then tell us please what I wrote about neural
networks and what was false. Please give the evidence.

BTW I dont intend to become n expert in neural networks by just reading 5
articles in the internet. I never heard of such a qualification method! You are
astonishing me.
