picochess v0.9j – Stretch

DGT-Pi together with DGT-3000

This release brings alot of new chess engines (versions). Here is a list what changed:

  1. Stockfish 7 updated to Stockfish 8. SF8 had a problem with time management but with the new OS it seems to be okay now
  2. Texel 1.06 to Texel 1.07
  3. Rodent III updated to v0.228 – For details see below
  4. Zurichess Neuchatel which also includes a bugfix for “alternative moves”

raspbian Stretch

picochess is only the software you use. But as everywhere else there is an operating system below it. For picochess we used raspbian jessie. But Jessie is rather old and most important it has only a outdated C-compiler with its libs installed. The newest rodent III engine needs something called c++14 but thats only available on the successor of jessie called stretch. Thats the main reason i call this release stretch and also you need a complete new image and cant update picochess by itself. The easiest way is (if you havent done this before) is to download one image file from “picochess-images” (see last chapter) burn this to your sdcard and update from there. All you need to have is this new linux system below and the rest you can do with picochess by itself. Please make sure, you really have such stretch image installed before you update to v0.9j. If you have problems please ask here or at the google forum. We are happy to help you.

Why thats then needed?

On former versions of picochess you cant use the pondering modes (that are all modes despite “normal”) together with rodent III which was a big disadvantage. Thats fixed now. Also you get lots of new personalities (i think its now over 60?).

Also this release brings the following features / bugfixes:

  • prepare for some uci chess engines like “demolito” which have a different (aehmm) idea of the uci protocol
  • in case you play a bullet game some features namely “voice”, “confirm messages” are turned off to get a smoother play feeling. Also the sliding factor is reduced to get a quicker answer from the dgt board. Since you have to hurry up anyway, i think its okay to reduce sliding detection in advantage of quick responses.
  • more tests for errorous times returned from the dgt chess clocks (reported from luigi)
  • some bugfixes on dgt-pi clocks
  • bugfix brain mode together with inside book (reported from peter).

  1. The new Stretch Version v0.9e works fine for me.
    Automatically update to Picochess v0.9j without any problems.
    Thx for your effort.

  2. Why 0.9j for DGT Pi; but not for RasPi? I‘m a chessplayer, not a computerfreak … and updating with the middle button don‘t work 😉

    • why are y always so negative?
      There is no image for RaspPi cause noone did it (see last sentence). You can update in many ways – images is not the only one -but for me, the most time consuming way.
      I always repeated that there wont be “tournament time controls” in foreseeable future. Its alot of work to do and in general i prefer to concentrate on making already implemented features running smoothly instead of total new stuff (see: route to v1). But yes, i will implement tournament system someday(!) its great – just not these months.

      Frankly: As long you dont offer money, you need to be more patient – after all picochess is done in free time by volunteers.

    • I would expect y take a look for the provided features before you buy any product.

      Sorry, im not (working for) DGT, from this 250€ i get -rounded up- 0,00€. All these versions i did in past >2years are done cause i enjoyed to do it.
      I deserve the right to do features in my prio (incl. even refuse to do it). If you want feature X ask nicely (and wait patiently) or hire someone to do it for you (incl. building images).
      I said already, these tournament times will come, but dont expect this in next months. Thats fair to tell everyone that for this particular feature y really need to wait longer.

  3. Hi Horst,

    if you complain about the DGT Pi – then you must address this to DGT and not to Jürgen. He is not in charge of supplying updates – this is a gentle Service for free. Btw: for 250€ you get a very good chess watch – and a very powerful and good chess Computer to Play with. This is remarkable. Of Course, there is always something to improve. I really enjoy the work of Jürgen and the Performance and improvement over time is outstanding.
    Relax

  4. Hi Volker,
    according to DGT, they are only responsible for the hardware. For the software, the programming of Picochess.

    I‘m relax … Stones or stoned 😉
