After some my Arduino project remains unclaimed touchscreen, so I decided to realize my chidhood dream to create a chess program. After a couple of months it wins me, but it is not big deal because i do not have any chess rating, just amateur.
This project uses Arduino Mega 2560 because of lack of operative memory on Uno, 2.8 inch touchscreen, passive buzzer, and about 2000 lines of code.
Program uses Negamax algorithm, iterative deepening, some kind of killer heuristic, time control. No any bitboards or hashes for obvious reasons. Evaluate function is rather complicated, but not too much, anyway in except of material it calculates figures activity, king safity, pawn structure. Solve speed about 100-200 nodes per second.
Play is according to chess rules, including en passant, castling, pawn promotion. Draw is determined too. Algorithm also may give up if did no see any vay to escape checkmate.
Board is rotatable, step by drag and drop, can take step back. It is possible to arrange the initial position, or load from Serial port in FEN format. Chess game can be saved in EEPROM and downloaded later, or replayed in fast mode.
There is a checkmate search regime to solve chess problem.
If anybody like to repeat this project, and screen not be the same model, i see only difficulty to calibrate touchscreen, need to tune coordinate transformation coefficients. Later i will remake sketch on more common and big 3.5 inch touchscreen.
Sorry for poor decor - it is my first public project.
Thank you for attention.

As i promised, updated sketch to 3.5 inch MCUFRIEND touchscreen 320x480 pixels. Added new variant.
Upd: 25 feb 2018:
GUI buttons explanation:
Start/Stop - to start/stop arduino thinking on current step and making step, stopping is not immediate
White/Black pawn - shows what color plays now, changable
Curve arrow - take last move back
10 sec.... - choosing arduino mean thinking time, may be twice exceeded in hard situations, it is difficulty level, from easiest to hardest 10 sec- 30 sec - 1 min - 3 min - 10 min - 30 min - unlimited. Hard level i mean hard to wait :)
Black/White mini board - rotates chess board
Question mark - Check Mate search mode, used to solve chess problem, in this mode algorithm finds only checkmates, 3-4 moves in reasonable time, and up to 6-7 moves without time limitations
Cellule board - turns mode to arrange the initial position, opens figures list (color changeable by pressing the pawn explained earlier), current figure changed by choosing, and may be placed on board by pressing cell, or cell cleared, if currend figure is empty box.
Loudspeaker - turns on sound or mutes (almost).
In arrange position mode extra buttons appeared:
USB(FEN) - load position from usb port in FEN format
Start chess position - to start new game
Empty board position - to arrange custom position
Running man - to fast replay position from first step, may be stopped
Arrow from square - to save current game in EEPROM (non-volatile memory of arduino)
Arrow to square - to load game from EEPROM (saved earlier)
About how to play - just drag and drop figure proper color, illegal steps will not be done. To make castling move king to last position after castling.

Added Arduino DUE variant 320x480.
Used MCUFRIEND 3.5 inch touchscreen ILI9486 with Bodmer TFT_HX8357_Due library
https://github.com/Bodmer/TFT_HX8357_Due
modified to support ILI9486. Touchscreen XPT2046 with URTouch library.
http://www.rinkydinkelectronics.com/library.php?id=92
EEPROM was replased with DueFlashStorage
https://github.com/sebnil/DueFlashStorage
Some improvements added - GUI (drag and drop due to absence readPixel function replaced more easy discrete movement), added 3 secs mode because of about 5 times acceleration of algorythm in comparison with Arduino, and maximal depth of solving tree growed.
Also buzzer moved to pin 12.
Upd: 15 mar 2018:
To add automatic answer from opposite side of chessboard after 5 sec waiting (to possibly make move back) add this bold string in loop() procedure
loop() {
gui();
if (!solving && rotate==cur_step%2 && millis()-lasttouch>5000) { solving=true; lasttouch=millis(); }

Arduino Mega Chess for M5Stack
Upd: 25 sep 2018:
For project for completeness i try to make 3D printed case. As mobile power source it will use one 18650 lithium battery and feed from 5v output DC-DC adapter/charger, what possibly give more than 10 hours working time. Case size is enough to fit 3.5 inch touchscreen too, at least version i have, only case cap need to be changed.
After print it appears that size of touchscreen window is little bit extra for 2.8 screen, and not bad corresponds to my 3.5 MCUFfriend touchscreen, as it seen on picture. Power source still from USB because charger module is on the way.

Added new project ESP32 chess engine
https://create.arduino.cc/projecthub/Sergey_Urusov/esp32-chess-engine-c29dd9
It may be combined with Arduino Mega chess GUI in future.
Upd: 12 mar 2019:
In addition, i tried to use chess engine for esp32 for arduino mega. Finally, it fits into limited arduino memory and shows 1995 ELO rating on 2 minutes per position. Combined with GUI it slowes down a little, but not too much, just about 10-30%, and calculation speed is about 500-1000 nps.
Upd: 21 mar 2019:
Arduino Mega Chess II in progress. It was surprise for me that test on Elometer.net shoed 1926 ELO raiting in fastest mode - 5 sec per posiition - far avay from my own possibilities. And it is on 16 Mhz 8 bit chip with 8K operative memory!
This version has possibility to autoplay with themselves, algorythm can give up if did not see way to escape checkmate. Play in debute mode is not strictly determined - there is some random variety. Still no open book.
GUI has 2 possible graphics resolutions - 480x320 and 320x240 pixels. Alpha-testing still going...
