# postflop workbench

postflop is a heads-up no-limit hold'em postflop GTO solver. The engine is
written in Rust and runs Discounted CFR (Brown and Sandholm 2019) with a
full best-response exploitability calculator, so every convergence figure
it reports is measured against the current average strategy at every
report interval, in chips and as a percentage of the pot, not just
asserted.

## Who it is for

Poker players and researchers who want to solve or inspect heads-up
postflop spots, either for chip EV or under tournament ICM (exact
Malmuth-Harville equity from a payout ladder and per-seat stacks).

## What it does

The browser workbench at https://postflop-workbench.vercel.app runs the
Rust engine compiled to WebAssembly. Give it a board, both ranges, stacks,
pot, and bet sizings, and it solves the spot in the browser with nothing to
install, or load a solution produced by the command-line build. It shows a
13x13 strategy grid with per-hand action frequencies, per-combo EV
drill-down, a tree navigator, a 52-card runout selector, EV and regret grid
overlays, blocker scores, node locking, a trainer mode for drilling spots
against graded feedback, and JSON export that round-trips with the CLI. The
same engine also ships as a native CLI (`solver`) that runs on every CPU
core, for larger spots or offline use.

The marketing and launch-film site is at https://postflop.vercel.app.
