It looks like ginkgo is inspired by Wolfgang delmares checkcheck...

Wolfgangs program was capable to build fortress positions and create strange positions where it was not clear if the pieces move from bottom to the top or from left to right.

He once told me that if his program is not moving its pawns over 4th rank it cannot be mated.

The maximum he tried was getting a draw.
Seems ginkgo is inspired by wolfgangs thesis.

In the Niels Bohrweg I could not find the snellius building so I asked a local bus driver. He had to look it up. He also asked why. When I told him I came to visit the World Computer Chess Championship he looked at me like I was some kind of fool. Also he had never heard about it.

Most of them were unfamiliar. There were some Germans I don't know.

Also most players are only busy with their games and have nothing to do with visitors.

Now I know everything about Chinese chess. By the way sjaak II lost a game for it refused to move because it applied a fifty rules move which is not valid for Chinese chess.

I met Jaap van den Herik and I told him that I had read his book (partly) on Computer Chess at about 1985 or so I don't know the exact year anymore. I only remember that he also wrote about quiescence search.

I've been coming there for15 years and I still occasinally get lost on the campus in Leiden. I know a round-about route to get to the Oort building by bike, and the Snellius is across the road from there, so I'm able to get there ok if Idon'ttry to be smart and cycle there by a more direct route.

This one? i remember reading that sometime in the nineties. In fact there is a remnant of it in every program I've ever written, to this very day.

No I don't think so. It was more a thick promotion report of 300 pages or so. But I don't know anymore. It is 28 years ago. It only remember it was a thick heavy book and I lend it from the library in Enschede.
