Very interesting post, many thanks for sharing it.

Just to answer your previous post about Gavon. It does already have the ability to connect to DIY computer chess boards like Solus. Here are a few photos of my Solus autosensory board that I built myself connected to Gavon (20+ engines), Shredder (Windows XP), WChess (DOS) and Aart Bik's Chess app running on a Android tablet.

yes i know that one can connect gavon to a board. but not anybody has the time and the capability to build his own board.

btw. i have seen thomas nitsche (mephisto III) on the video too. although nitsches program did not participate in cologne 1986 he was there. when i remember it right he hold a speech about search tree techniques. new ideas. Minute 25'16", person on the left.

You are right, but you can buy at ebay a cheap mephisto modular board and a teensy chip to build yourself very cheap prototype of USB board only soldering some wires. (And if you don't want to work, a very interesting project for kids who like chess, electronics, computers and informatics to be developed this winter always under your supervision and funding)

After you had success in this task and play some games over your 'own' handmade chess board prototype, sure you start to think how to build your perfect chess board computer as we did in the 80's. As sure the kid learn electronic, chess and computing :lol:

I do understand. But for me a chess board is not nessesary.
I have many dedicated chess computers like Mephisto II or ruby or super vip or Mephisto mobil.
It would be enough for me to use an usb keyboard for Gavon to input moves with that keyboard .typing in coordinates is good enough for me.
Is it possible to use an usb keyboard with gavon ?

What this potentially cute little baby needs is a bespoke, high quality commercial grade, aesthetically appealing housing. The type of housing you pay a professional firm to design, mock up and then arrange production.

That way, we could end up with the 2015 version of the original Mephisto bricks (Mephisto II, etc - a cuty from the early 80s), albeit with the latest technology, multiple engines and a handy 1300 odd extra ELO points.

Yes. We need a designer in the team ;-)

Btw today my gavon came, connected it to a dgt board, works well. Playing first game with atroid 0.3 against challenger 24 mhz.
We will see if the Elo numbers are right.

Well I decided recently to buy a Gavon to see what the hype is. I can honestly say that I love this little computer.

If you want to play nostalgically (my preference) then you do not need to connect it to a chessboard at all. It plays just fine by using the 5 buttons and it has a ton of options to try out. A rating system to test your skill. Turn on the included speaker and a soft lady voice announces the moves.

Play it from the included power supply or from the included battery pack if you are travelling. The battery pack charge lasts you a long time and of course you can recharge it. No more buying batteries.

And it is tiny with a size of about 3.1/2" x 2.3/4" x 2" tall. You can drop it into your laptop bag and go anywhere with it.

And it is so strong, an ideal opponent for top dedicated computers, Ressurections, Revelations and finally even a worthy opponent for my Mysticum. What more can you possibly need?

Buy two and you can play tournaments against all the current 36 built in chess programs that range from strength from about 2900 ELO down to 1500 ELO. And if that is not enough, you can also adjust the strength of each of the included programs, if that is your choice. More chess programs are being added to it all the time and all updates are free.

Best of all, the playing enjoyment is just like picking up a Mephisto 3 or even a Novag Sapphire and playing it directly with the keys.

What is even more amazing is that you could buy 2 or 3 of these and it probably costs you less than what a Novag Citrine would cost you to buy.

It is brilliant and probably the best for value chess computer that I have purchased in all my time of collecting chess computers.

Thanks Josu and all the other people dedicated to this project, you are the best.

Best regards
Nick

Nick - did you purchase an assembled Gavon on eBay or build yourself? I can't find any items for sale from jbergaraede on eBay.

Thanks,

my experience is that the elo numbers given in the manual of gavon are IMO not correct.
we will have to play games to find out about them.

in the moment i am having gavon running in my tournament . first i try out faile 1.4 as engine.

results so far is:

a few moments ago i saw a strange behaviour.

gavon faile 1.4 played e.p. move when opponent played c5 it played with white b5xc6 e.p. and instead of writing bxc6 it wrote c6 !

i wonder if this is wrong in faile or in the gui of gavon.

my shredder sees the pgn this way:

[Event "40/120, Oldie-Turnier"]
[Site "SCW"]
[Date "2015.02.22"]
[Round "1"]
[White "Gavon Faile 1.4"]
[Black "Fidelity Designer 2265"]
[ECO "A00"]
[Result "*"]

1. a3 e5 2. c4 Nc6 3. Nc3 Nf6 4. b4 d5 5. b5 Na5 6. cxd5
Nxd5 7. Qa4 Nxc3 8. Qxa5 Ne4 9. Nf3 Nc5 10. Qc3 e4 11. Nd4
Be7 12. e3 Qd6 13. Bc4 Qg6 14. g3 O-O 15. O-O Rd8 16. Qc2
Bh3 17. Rd1 Rd7 18. Bb2 Rad8 19. d3 Bg4 20. Rd2 exd3
21. Bxd3 Nxd3 22. Qxd3 Qxd3 23. Rxd3 c5 24. bxc6 bxc6 *

but gavon writes 24 c6
in the display.

we will have to play games to find out about them.

in the moment i am having gavon running in my tournament . first i try out faile 1.4 as engine.

Hi Thorsten,

I think I saw the same yesterday with a move cxb3 ep. so there might be a small error somewhere. However the game continued correctly so it might be just an error on how it is displayed maybe?

I agree, with the elo ratings being too low. But I also expected this as I have played low rated computer programs before in the past against dedicated machines and the same was always the case.

Best regards
Nick
