Very nice and pretty-looking GUI!
One minor notice thought - as i figured, engine give eval according its own side (ie +200 means engine is winning),
but it is not always convenient. I think it is a good idea to add some feature like "show eval from White pow" tickbox later.

Gave some thought, but managed to squeeze a win.
TC for the engine "instant response" - usually calculated ~d6.
I used ~5 min in total i think.

I enjoyed the game, thanks!

Will there be an option to under promote the pawn (all I got was an instant queen). Unless I'm missing something.

Thanks

Bearing in mind the fact this GUI was live coded on youtube I tried to keep things simple.
Obviously adding a feature of choosing piece to promote can be added.

As I thought... BBC plays decent chess when it has an opening book and a real time control (not 3 seconds per move). :)



BTW.... Maksim...I made a logo for him too. ;)

Okay, so I played BBC 1.2 under equal conditions.

- BOTH of us played under 3+2 time control (international blitz standard).

- I had ZERO view of PV (so I can't see his thinking or eval)

- BBC Chess used a polyglot book made from all the games from every Linares, Tata Steel, Dortmund and World Championship match ever played (so only elite human games)

The Game: Not sure what to make of it. I sacrificed (lost?) a pawn, but prevented him from castling, locked up his rook and had active pieces...

Somehow this was enough to induce a tactical mistake where he allowed 23...Rxf3! winning material and the game.

I was black.

Hi Maksim,

I've been trying BBC online (and have version 1.1 and 1.2 installed as well). Some observations:

- In the Fritz GUI, BBC only reports 650 nodes (not kNodes... 650, as in under 1000) per second. I assume you're passing this wrong to the GUI. (I haven't checked the code). This would be extremely slow.
- Online, BBC 1.3 reports 150.xxx kNodes. That would be 150-250 kNodes/second. That seems more correct, but it's still slow; it's 1/4th to half of the speed of my three year old midrange phone, or half the speed of a Raspberry Pi 4. Where is the engine running?
- The NNUE 1.3 version is much weaker than the BBC-version I played earlier. That version was quite difficult to defeat for me even at instant response. (I'm a decent, but not super-strong player; somewhere between 1800 and 2000 FIDE Elo depending on how much effort I put into a game.) For earlier versions of BBC I would actually need to put in some effort to not lose a game. Here's a game I played against 1.3 + NNUE, where my response time was basically as fast as you'd see in a bullet or 3 minute blitz game... (and I suspect I made many mistakes and left a lot of chances unused). Basically, I put no effort at all into this game. Especially black's 36 ... h5 boggles my mind. It just completely ignores an attacked bishop. During the entire game the engine didn't even make an effort to get castled.
