Havoc - New Gothic chess engine

[JohnWoe]

I have been lately writing a new engine from scratch. Havoc engine. My main engine probably.

I've been finding more and more speedups and tricks.
And to my surprise today Havoc 0.7 scored: 4 wins and 6 losses against Fairy-Max 5.0b in 3+0 games.

Site I made for Havoc: https://samuraidangyo.github.io/

Sample game. Havoc doesn't have lots of knowledge yet.
Absolutely no mating heuristics. Still it finished Fairy-Max easily.

Congrats with chess variant!
It's really fun to implement chess variants when you already have a solid bases.

[JohnWoe]

I have been lately writing a new engine from scratch. Havoc engine. My main engine probably.

I've been finding more and more speedups and tricks.
And to my surprise today Havoc 0.7 scored: 4 wins and 6 losses against Fairy-Max 5.0b in 3+0 games.

Site I made for Havoc: https://samuraidangyo.github.io/

Sample game. Havoc doesn't have lots of knowledge yet.
Absolutely no mating heuristics. Still it finished Fairy-Max easily.

Congrats with chess variant!
It's really fun to implement chess variants when you already have a solid bases.

Thanks!
Also thanks to hgm for XBoard + Fairy-Max both good for developing Havoc.
I actually enjoy watching Havoc play Gothic chess. I have 100% retired from standard chess.
Maybe Capablanca/other variants when Havoc is much stronger. Should be super easy to add.

Surprisingly Havoc is already pretty good.( Weaker than Fairy-Max 5.0b. It just started to play non-illegal moves today. ) For example make/unmake is much better than what I have in Mayhem.
Havoc has Mayhem's search but no extensions/Null move/etc yet.

You have lots of engines. I have already lost count. As your latest great JavaScript engine for Xiangqi.
I was thinking about JavaScript too. But I'm so lazy I write everything in C++.

Another teaser.
Havoc 0.7 finishes the deal with archbishop + chancellor.

Great job! And yes, once you have watched a few games of 10x8 chess, the orthodox FIDE version suddenly seems exceptionally dull...

Congrats with chess variant!
It's really fun to implement chess variants when you already have a solid bases.

Thanks!
Also thanks to hgm for XBoard + Fairy-Max both good for developing Havoc.
I actually enjoy watching Havoc play Gothic chess. I have 100% retired from standard chess.
Maybe Capablanca/other variants when Havoc is much stronger. Should be super easy to add.

Surprisingly Havoc is already pretty good.( Weaker than Fairy-Max 5.0b. It just started to play non-illegal moves today. ) For example make/unmake is much better than what I have in Mayhem.
Havoc has Mayhem's search but no extensions/Null move/etc yet.

You have lots of engines. I have already lost count. As your latest great JavaScript engine for Xiangqi.
I was thinking about JavaScript too. But I'm so lazy I write everything in C++.

Another teaser.
Havoc 0.7 finishes the deal with archbishop + chancellor.

Bug fixes and analyze/undo mode added. XBoard protocol is superior to UCI in every way.

Havoc contains no endgame knowledge yet. Rule50/3 fold reps are supported already.
Now I can test endgames on XBoard.

Great job! And yes, once you have watched a few games of 10x8 chess, the orthodox FIDE version suddenly seems exceptionally dull...

Thanks.
Yes 10x8 is much more interesting.
All the variants in XBoard/Cutechess look more interesting than FIDE chess.

That's why I wanted to get rid of globals and go OOP.

Great job! And yes, once you have watched a few games of 10x8 chess, the orthodox FIDE version suddenly seems exceptionally dull...

How about 10x10 chess? I'm tempted to give Grand Chess (https://en.wikipedia.org/wiki/Grand_chess) a try later this year. I haven't tried playing any of these large-board variants for more than a handful of games, but Grand Chess always looked like the most attractive of them to me.
