Forkside
Prompt
A chess tactics learning website (starting at 1440×900, responsive down to 390 pixels wide), with an English interface, for amateur players rated 800–1600. Teach one tactic at a time, such as forks, pins, skewers, and discovered attacks, with step-by-step board explanations followed by a few puzzles.
The core is arrows and highlights appearing on the board step by step with the explanation. When a correct move is made, such as a knight jumping to a fork square, two attack lines light up simultaneously. An incorrect move should show the opponent's specific response rather than merely saying “wrong.” Make the pieces and board refined, with materials created through image generation or 3D rendering rather than default piece icons.
Design three states: a lesson explanation; solving a puzzle; and the tactic revealed after solving it.

一个国际象棋战术学习网站（1440×900 起，响应式到 390 宽），界面用英文，给等级分 800–1600 的业余棋手：一次学一种战术（双攻、牵制、串击、闪击），每课先在棋盘上一步步讲解，再做几道题。
讲解时，棋盘上的箭头和高亮跟着讲解一步步出现；做题时走出正确一步（比如马跳到双攻格），两条攻击线同时亮起；走错时给出对手具体怎么应对，而不是一句“错了”。这是这件作品的核心。棋子和棋盘要精致，用生图或三维渲染做出材质，不用默认棋子图标。
设计三个状态：一课的讲解、做题进行中、解出题目时战术揭晓。
