GTO Preflop Poker
A Texas Hold’em strategy-learning and probability tool
You finish a hand and lose.Was the decision wrong, or was it only bad luck?
What it solves
Most poker players know the moment: a hand ends in a loss, but it is hard to tell whether the decision was wrong or the luck was bad. A win can be just as unclear. Did you play well, or did the opponent hand it to you? Review by feeling alone, and the result is still only a feeling.
This Mini Program replaces that feeling with a number that can be calculated: expected value, or EV. At every decision, it shows the best option and how far your choice fell behind it. The result of one hand is noise; EV loss is the long-term scorecard.
What it can do
Calculate
Real-time calculator
Set up a hand for two to ten players, enter the hole cards and board, and immediately see equity and the expected value of each action. It is the fastest way to test a specific situation.
Learn
Illustrated lessons
There are eight illustrated rule sections, eight strategy lessons from position through ICM, a glossary of ninety terms, and four real hands broken down action by action. You can begin without already knowing the language.
Practise
Decision training
Deep-stack training runs continuously at a six-handed 100BB table. Tournament training adds rising blinds and re-entry, with decisions calculated by ICM equity. Every decision receives feedback, and the review centre lets you replay each hand and see where EV was lost.
See through
Tianyan teaching mode
This reveals information normally hidden: a 13×13 heat map of an opponent’s range, expected-value comparisons for each action, and equity changes across streets. Turn it on for study; turn it off for a normal hand.
How to begin
For a first visit, this order works well:
Read “What is GTO?” on the home screen. Three minutes is enough to understand what the tool is calculating
Review “Basic Rules” if needed, or skip it if the rules are already familiar
Play a few hands of “Deep Stack”. Advice is on by default and shows the best option at each step
Open the review centre afterwards, replay one hand, and find where your decision lost EV
Use the real-time calculator when you want to rebuild and study one exact situation
For the shortest route:
Play ten deep-stack hands, then go back through the review.
Most of the rest becomes clear on its own.
Who it is for
- People who can play but cannot clearly explain why they made a decision
- People who want to understand EV, ranges, and ICM but struggle to learn them from articles
- Tournament players who get lost around the bubble
A few notes
- It opens without registration or login
- All calculations happen locally, with no network requests and no information collected
- There is no betting, top-up, or exchange. The numbers in the interface are training points that cannot be bought, sold, or redeemed
- Advice is the highest-EV choice against the built-in opponent model, not a pure GTO solution. It evaluates decision quality, not the result of one hand
