Hi Jim,

I was testing the Android build of PlentyChess 6.0.15 JA and noticed what seems to be a bug. The engine played a self-match at 1+1 time control, and the moves looked highly irregular and uncharacteristic for its strength.

Here’s the PGN of the game:

[Event "?"]
[Site "?"]
[Date "2025.08.07"]
[Round "?"]
[White "PlentyChess 6.0.15 JA"]
[Black "PlentyChess 6.0.15 JA"]
[Result "*"]
[TimeControl "1+1"]

1. e4 e5 2. Qh5 Nf6 3. Bc4 Qe7 4. d3 Nxe4 5. dxe4 g6 6. Bxf7+ Kxf7 7. Qe2 Qe6
8. Nf3 Kg7 9. b3 Be7 10. Qd2 h5 11. Bb2 d6 12. Qc3 h4 13. Nbd2 Na6 14. b4 Rh5
15. b5 Nc5 16. g4 hxg3 17. fxg3 Bd7 18. Qa5 *

The early queen sortie, repeated odd pawn pushes, and self-blocking moves don’t match the engine’s usual style. I suspect the Android compilation might not be functioning correctly (possibly a parameter or NNUE load issue), since the PC build doesn’t produce similar play.

Could you check if there’s an initialization or NNUE loading problem in the Android version of 6.0.15 JA?

Thanks for your work on PlentyChess — it’s normally a great engine!


Joseph.

Hi Joseph,

I can confirm. It's playing badly for me too. I'll take a look.
