My new engine will be trying the exact same thing.

My new engine will be also trying the exact same thing.

I'd love to make a chess bot on Scratch but I get stuck at the chess engine - I just usually can't be bothered to create a working board with move input and valid move detection, it'd take too long and I'd never get to the bot part.

LA wins against Amarillo (20 secs)

Just learn programming. Creating a chess engine is a really impressive travel…

Perfect game with 97% accuracy

Please note, that Amarillo is always Unstable until I make the full release. This Version for example had broken Q-Search due to incorrectly Implemented Delta Pruning

LA stable??? It’s like saying that Destructor or ludoknight or turboknight can be stable…

The Agent Lv3 Romantic personality crushed Delta at move 15 and Delta glitched and stopped moving

Id be interested in a game where you run Delta on Turbowarp.

I did just understand that Agent is the ElapElap's chess engine :skull:

I'm back to working on my bot, and I've decided to start with python, then implement the code into scratch afterwards. I have minmax, alpha-beta pruning, pst tables, pawn structure, king safety, and castling evaluation functions. What is the next step from here? From what I see, implementing a NNUE could work - I have experience with Resnets for image classification, but attempting to make a NNUE failed spectacularly. So outside of a NNUE, how can I improve the bot?

Have you tried improving the Move ordering? If not I'd recommend you look into History Moves and MVV-LVA

Hey, any suggestions for commands I should add in the terminal of my new engine?

lol, fair enough. Using ID (iterative deepening) is a huge improvement over just plain depth-limited search, as during more forced lines, it can gain a few ply. (It's probably also just a better user experience, for every move to have a predictable amount time-use.)

Hasi istg please add at least a legal move detection
Yellow (Amarillo) played O-O-O and O-O in the same game

Anyways easy LA W

GoK Classic grinds down White Dove in 82 moves, great game to watch!

Both engines are able of threat detection, which gives them a competitive edge over other HCE engines.
