AGENTPOKER — Heads-Up vs DeepSeek

Retro CRT-styled heads-up no-limit Texas Hold'em. You vs DEEPSEEK, an agent powered by deepseek-v4-flash reached through a Cloudflare Worker proxy (the API key lives only in the Worker's secret bindings).

Features

• Full no-limit hold'em rules ported from the lemon_poker Elixir engine (65 ExUnit tests) into a dependency-free JS engine: blinds, betting rounds, min-raise sizing, all-in short-raise no-reopen rules, side pots, split-pot remainder by button order, wheel straights, kickers.
• Multiple chip denominations (500/100/25/5/1) rendered as chip piles.
• Heads-up blind/button rotation; big-blind option; all-in runout.
• Agent decisions streamed via https://poker-agent.z80.workers.dev (Cloudflare Worker → deepseek-v4-flash). If the network drops or the model answers illegally, the game falls back to a legal action — it never stalls.
• Retro CRT terminal aesthetic: scanlines, phosphor glow, pixel fonts, WebAudio blips (toggleable).
• Configurable buy-in, blinds, match length, and agent speed.
