go movetime 1000bestmove c7c5 ponder g1f3- what is ponder? Something to do with thinking on the opponent's turn: permanent brain.
- understand the previous lines
To make the move it as suggested for black, we have to either repeat the entire sequence of movements:or alternatively we could also use the previous FEN notation as a starting point;Note how the Universal Chess Interface interface is very simple: we just load a state and then decide what to do next for that one state. The engine holds only one and exactly one state at a time, and you can't even modify it differentially without loading new one from scratch.

Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01webpack/template contains a reasonable starter template.
This will produce, under
dist/ the following minimized files:dist/index.html: from webpack/template/index.html. You can open it to see:show on the browser. This was added from JavaScript.Hello webpackdist/index.js: from webpack/template/index.js and anything in its import tree, e.g.:- webpack/template/main.scss: sass source. It gets embedded the the JavaScript output as a string, and the JavaScript then applies it to the page, making the font blue

You can also run this test with the development server on localhost:9000:which uses unminimized outptus, and automatically push reloads the page whenever you change any of the input files!

Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01This example shows how to use @cirosantilli/_file/webpack/webpack/sass.
To make things simple, it generates a completely separate
dist/index.js and dist/main.css which are manually included from index.html, and does not do any type of injection (neither Js into HTML nor CSS in Js). @cirosantilli/_file/webpack/webpack/no-js-inject by Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01
Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01This example shows how you could manually include the
dist/index.js that is output from webpack into your index.html.This is generally not what you want to do, because what you actually want to do is to use a Js output name with a hash in it, so that browsers only need to refetch when the name changes.
And to do that, we have to let webpack dynamically inject that unpredictable hash as done in webpack/template with:
new HtmlWebpackPlugin({
filename: 'index.html',
// Inject the include to our hashed filename,
// since it is not deterministic due to the hash.
inject: true,
template: path.resolve(__dirname, 'index.html'),

Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01AMO is a slightly more general area than condensed matter physics, including related phenomena with smaller numbers atoms and optics. The two terms are however sometimes used as synonyms. The term AMO has gained wide usage and acceptability, see e.g.:
If Ciro had had greater foresight, this might have been what he studied at university!
