Preflop and postflop GTO solutions in your browser, nothing to install

ART/GTO gives No-Limit Hold'em players GTO solutions in three ways: a Viewer that runs in the browser, free preflop ranges you can download, and a desktop solver for your own postflop spots.

All preflop ranges are free. One postflop spot is free too, and a beta key opens the postflop library.

Preflop

The ranges are solved for 100bb deep, 6-max No-Limit Hold'em cash. They cover opens, calls, 3-bets, 4-bets and 5-bets from every seat, and the multiway lines that follow them. Read them as charts, click through them in the Viewer, or download them.

Download all 2,606 preflop ranges

The download is the free Viewer ZIP. The ranges sit in its ranges folder, one plain-text file per action and line, with each hand's frequency in percent, as in [75.00]AsKs, AhKh[/75.00].

Not for commercial use. These ranges are free for your own study and play. You may not sell them or use them in a paid product or service without written permission from ART/GTO. Ask us.

Postflop

The Viewer shows every node of a solved game tree: the strategy for each hand, equity, and how each turn or river card changes the picture. The Aggregate Report sums a line up across all solved flops.

The free spot is open to everyone. To open the full library during the open beta, request a beta key. To solve your own spots, use the Solver. Its .artgto export is open and documented, so you can build your own tools on it.

Also free

Poker calculators for variance, equity, pot odds and ICM, GTO lessons, and real hands with the solver's answer.
