Grand-master Level Chess without Search: Modeling Choices and their Implications

Yoav Golderg, February 2024.

---

Researchers at Google DeepMind released a paper about a learned systems that is able to play blitz-chess at a grandmaster level, without using search. This is interesting and imagination-capturing, because up to now computer-chess systems that play at this level, either based on machine-learning or not, did use a search component.[^1]

Indeed, my first reaction when reading the paper was to tweet wow, crazy and interesting. I still find it crazy and interesting, but upon a closer read, it may not be as crazy and as interesting as I initially thought. Many reactions on twitter, reddit, etc, were super-impressed, going into implications about projected learning abilities of AI systems, the ability of neural networks to learn semantics from observations, etc, which are really over-the-top. The paper does not claim any of them, but they are still perceiv

Vue Global Keyboard Shortcut Mixin

This is a Vue.js mixin (or rather, a mixin factory) for simple keyboard shortcuts.

Features:

• Tiny (<0.5 KB minified & gzipped)
• Super easy to use
• Proper restrictions (does not trigger when modifier keys don't match exactly or when an element has focus)

Note that this mixin targets modern browsers. If you need legacy browser support, you need to use a transpiler like Babel with the according polyfills.
