Analyze games or play vs Leela Chess Engine in Analyze This app

UPDATE (Jun 2020): Its now even more easier to use Leela Chess in Analyze This app (pro). Read here.
—
Computer Chess has made a tremendous amount of progress in recent months. And especially, Leela Chess! Earlier, Leela Chess ala lc0 only worked on special hardware.

But recently, its been made to work on Android too! This is fantastic news for so many Android users, which means the Engine can run natively on the phone (without connecting to any cloud service to run the engine)

NOTE

  • This only works for Analyze This on Android. Not in the Analyze This iOS app.
  • Its still a work in progress and these are not official builds. Means there could be some problems that you may encounter
  • Thought lc0 did beat Stockfish earlier, but we cannot currently expect that kind of performance on our smartphones, since lc0 really is powerful when running on a GPU. For the most powerful analysis need, Stockfish would still be a better option for your phone. If you need variety or more human like moves, then go ahead and try lc0.
  • So lc0 will still be quite weak, but it can very well perform at a GM level, depending on your device.
  • The below download links have a built-in “weights file”. In the near future, via an app update, we will provide an option such that you can specify a different weights file for varied strength.
STEPS
To run lc0 engine in Analyze This app (both Free and Pro version):
 
DOWNLOAD OPTION A (Download on PC. Unzip. Copy to phone)
  1. Download the engine with built-in weights. Either this or this (if 32bit armv7 device) or this or this (64bit architecture). If not sure, you can very well download both the zips
  2. Unzip the file. Copy the content which is inside (lc0) onto your phone’s sdcard

DOWNLOAD OPTION B (Directly on phone)

  1. You can download the file directly on your phone. Link 1 (32bit armv7) or Link 2 (64bit)
STEPS IN ANALYZE THIS APP
  1. Now fire up your Analyze This app
  2. Tap Board Actions Menu  -> Manage Engines
  3. Tap INSTALL ENGINE option at the top
  4. Locate the lc0 engine file which you unzipped and copied in Option A OR the one that you downloaded in Option B.

Thats it! If the engine file is supported on your device, you now have Leela Chess working on your Analyze This app. You can analyze your games with a more human touch.

Or you can also play a few games using the Play This Side option!
HOW TO PLAY
Tap the name of the Engine and choose Play This Side. Engine will play the currently selected side, while you can make moves for the other side!

AnalyzeThis just got Stronger, Better & Prettier

Today’s AnalyzeThis update brings the most powerful open source engines, Stockfish 2.2 and Critter 1.6, at your finger tips!

What’s new in v1.2
☆ Critter & Stockfish just became even more stronger! Critter upgraded to 1.6 and Stockfish upgraded to 2.2.


☆ Start/Stop engines. Now you have the power to simply turn off one engine, while the other engine is digging deeper into the position. Lesser battery, better results!


☆ Increase/Decrease engine primary variations/lines. Wish to try some more variations from the engines? Just press + and the engine will provide you with additional primary variations.


☆ Edit board added. Now you can set pieces manually

☆ Copy game as PGN. Future versions will have direct PGN Load/Save support. Till then, you can manually Copy the game as PGN using this feature and paste in your favorite program.


☆ Takeback and move Forward buttons! Yes, yes I know. The existing method was not always intuitive and would also cause false touches. Now, you have dedicated buttons that get out of your way (hide themselves), so that you can just focus on the position!


☆ Other enhancements and stability fixes. Show/Hide board coordinates. See App Settings.

New ‘Analyze This’ app and updates to iChess & Chess Book Study

Today, I am happy to release my 3rd Chess app for Android devices, ‘Analyze This’.
Its a unique app which gives you the power of two Chess engines, simulataneously!

As soon as you fire the app, Stockfish and Critter, two well known strong open source engines, start chewing the position and provide instant analysis.
If you find an interesting position while reading a chess blog, just paste the FEN notation in ‘Analyze This’.

Note: It is NOT an app for playing against the mobile.
