RelaxChess 7 is available

[Richard1964]

RelaxChess 7.3 is available. It has much better improved memory management since modern GUI's as Arena hold executables continue in memory. This is different playing with engine as DLL (library) since it is loaded only on demand so you do not have to worry so much about possible memory leaks. And one remark to the previous post of someone, promotion e7e8=Q/e7=Q is a valid PGN notation (has nothing to do with uci protocol ).
Password remains the same (it means very red vegetable :-0 )

Ouch, so you did not change the wrong behaviour with no specified promotion piece yet?
I don't understand why you did not read carefully what I wrote and even debugged, one post before you announced the new release now.

It was very visible already in my previous post

Code: Select all

White makes an illegal move: f7f8
Black makes an illegal move: a2a1

There is NO promotion piece at all, just (buggy in various circumstances) Arena let you escape, because it assumes for you, you might have chosen a Q.

Here a fresh game now showing the same behaviour.

The move format is in long algebraic notation.
A nullmove from the Engine to the GUI should be sent as 0000.
Examples:  e2e4, e7e5, e1g1 (white short castling), e7e8q (for promotion)

There is new version of RelaxChess game 7.4 in Windows store. There are couple improvements and fixes in chess engine. These changes can be noticed the best in Expert mode and running on a fast laptop (max. think time). The free available Windows and Linux chess engines are also updated. The big advantage of RelaxChess software is thanks to modular build and own chess test framework making changes is not so difficult.

[Richard1964]

The RelaxChess 7.6 is available Microsoft store. The C++ DLL chess engine is smaller and much more powerful than previous versions. The attacks and sacrifices have been completely rewritten. There is also important GUI change. Since now the newest engine versions are only available in Microsoft store (together with RelaxChess game). Free available chess engines on github are based on older versions.

The latest solid rock RelaxChess game is since yesterday available in Microsoft store. I have recorded a match, commercial RelaxChess engine (C++) against RelaxChess open engine written in Java in RelaxChess GUI (available on github). The winner you can see in 46 seconds (long game) here https://www.facebook.com/54718905537560 ... 0374712877. The RelaxChess game is available here https://www.microsoft.com/en-us/p/relax ... f45rd240hn
