I hope it's not too boring, an old guy behind a screen, making a move every few minutes  .
If I win all games of the first four days, I'll consider hanging Kobus around my neck on the fifth day.
This may add too visual entertainment, and since I'm trying to show that computers still lack 'intelligence' it may also provide some balance by proving without a doubt that humans may lack intelligence too  .

When I got him, eleven years ago, he was 3.5 m and weighed 20 k. Now he's 4+ m (couple of cm past 4) and weighs 30+ k.
In ten years I'll be 75 (Whoever's-Up-There willing) and he'll be 4.5 m 50 k. By that time, or earlier if I die or get otherwise incapacitated, I've reserved a place for him at a reptile zoo in Vlissingen. I think it would be wise by then not to invoke Murphy's Law, lest I should become an item in "What a Way to Go" .

It's now human 5 - bots 1, so I've lost the match, 4 games to go. The results are very interesting:- The bots have become significantly stronger (except Lajkonik in the first game, where it played like version 1.3 instead of 3.1)
- They also contribute to strategic insight. The 'clusterbombs' they employ give more tempo than most players would anticipate, and these must be defused at an early stage (at the price of tempo of course)
- The games are of a high standard, and I enjoy them tremendously - and I still want to go for the best possible result of course
 - Obviously I was wrong about the level of play of the bots.
My congratulations go to Marcin Ciura for his win in the second game!

Final score, 8-2 in favor of humanity. Well done, Christian! Too bad you lost the 1000 euros, but you are obviously still way ahead of the machines.

Are you sure it's 8-2? I read somewhere else that the score was 7-3.

Oh, then it is probably my mistake. I didn't see the final games live.

Christian, congratulations on a 7-3 finish. If it had been best of 10 you clearly would have won. But you structured the challenge to very difficult for yourself. When I was talking to Fritz about it he mentioned that you would need to be about 350 rating points higher than the bots to pull of a streak of 10 wins. Earlier this year I play 10 postal games with bot Castro (the strongest of the current bots in rating) and had a 5-5 record against it. I've been playing Havannah for years now and Castro already seems to be on par with me.
Congradulations to Marcin Ciura also on winning the challenge and creating a strong bot.

That was great fun
The games: I hate analysis but here's the overall impression.
The first game Lajkonik presented itself as dumb - that's perfectly legal. It's not reversable either: I can't lure a bot into thinking ...
There was a second game that went wrong due to a connection bug. I wasn't too happy with the position at the time it was aborted. I should have been warned.
The next second game I chose the wrong strategy, plain and simple. You can't outrace a bot when it indicates readyness to engage. I thought I had the decisive tempo. Mea culpa.
Then wins up to and including the 8st game. All based on a strategy of enclosure at two sides because the bots prefer cluster bombing with ring threats for making speed, and will usually keep expanding close to the main structure, and very effectively at that, given the object.
In the 9th game I was already fairly exhausted, but I think I had the decisive tempo when I accidentally submitted a move instead of removing the stone I had been analyzing. I had a direct threat in two to answer and was well aware of that. Analysis will probably reveal I had a won position, but (sh)it happens  .
In the final game against Castro, I saw a catastrophic move in the replay. Early on I placed a 'defensive' stone under a delusion that I was unware of at the time, like all delusions, but that I immediately spotted on replay: the danger was an illusion. That not only cost a tempo (and I was playing second as it was), but once you stick your foot in it, there are suddenly additional moves necessary, and Castro expoited that very good. From that point on I was running behind the facts.
My congratulations go to Timo and Marcin, and my thanks to all involved, Richard Lorentz, Ton van der Valk, Albert Vasse, Jan Krabbenbos, Frans Faase, Arty Sandler and Ed van Zon.
P.S.
I burned my ships behind me in the 5th game (I think) when I went for a bridge, because I didn't see how it could be prevented. I could have kept the option while securing a forkframe, but because I couldn't see it, putting it all on that one card seemed more aesthetical (hear the bots laughing).
Fortunately the bot didn't see it either. Jos Dekker saw it, and Ton van der Valk confirmed it: the bridge could be prevented. So I got away with it .

Thanks for the brief analysis Christian.
Here are the links to games. You first have to login to http://www.igGameCenter.com/ for the links to work.
Game 4 is still set to private so it can't be viewed.
To step through the moves you first have to click on one of the arrows under 'Move History'; then you can use the forward and back arrows at the top of the list.
