In short: it's our exploit playbook overlaid on YOUR game — a map of the situations where players at your level make the most mistakes, showing how much you're (or aren't) capitalizing on each one.
Plan: Pro 🔒 (part of the full Diagnosis)
Changed on 24 Sep 2026: the Study Tree is no longer a separate tab — it became the flop-type filter inside Exploits. The old address takes you straight to Exploits.
The idea behind it (read this first)
Most apps give you numbers about you. The Study Tree does the opposite: it starts from the mistakes of the field — the population of players at your level.
We took a huge volume of real hands from the micros (NL2 to NL50) and mapped where that population makes systematic mistakes: where it folds too much, where it calls too much, where it doesn't bet the value it should. That research produced an exploit strategy — the right play to punish each of those mistakes. It's our "Blueprint."
The Study Tree takes that Blueprint and overlays it on your hands. The result answers the question that matters: "In the situations where the field gives away chips, am I taking those chips — or leaving them on the table?"
This isn't "right vs. wrong by GTO." It's "the field messes up this way → you punish it this way." The yardstick is the money the population at your level drops, not theoretical equilibrium.
Where it lives now
Menu Cash Game → Diagnosis → Exploits. Top to bottom:
- Your score (0 to 10) and how many exploits you found × left on the table, by play type (Value, Bluff, Defense…).
- Your next exploit: the spot that costs you the most in bb (with 10 or more mistakes), the right play with the field's number and the See these hands button — and, below it, Where you leave the most, the list of the spots that cost the most.
- Your spots: the list of situations (e.g. "You opened and got called, out of position"), from the one where you leave the most exploit to the least. Spots with fewer than 20 opportunities go to the end, without a score — no reading based on a handful of hands.
- See the full map (spot × flop type): the old Study Tree grid, collapsed. It only shows your %; grey = fewer than 20 opportunities (the number is how many). Clicking a square opens that spot already filtered on that flop type.
What you see when you open a spot
- Where you leave exploit in this spot: the right plays you most often skip there (e.g. "Bluff — a line where the field gives up too much"), with how many you made × left.
- Filter by flop type: the 9 board families (Ace-high dry, High-card dry, Broadway connected, Middle connected, Low dry, Two-tone with draw, Monotone, Paired high, Paired low), each with your %. Picking one shows what defines that flop and who it favors.
- Your most repeated mistakes: the 3 most frequent mistakes in the slice, how many times they happened, what you did (✗) and the right play (✓). Only mistakes repeated at least twice count.
- Hands: Left on the table and Got it right tabs, as a list — each hand with your cards, the board, the streets, the play type, the date, the result in bb and the mistake written next to it. 20 per page, with page navigation. Review opens the replay with the decisions street by street.
Why did bb leave the map? In a cell with 1 to 3 hands, the bb result measures luck, not whether you made the exploit (AA losing 100 bb on a correct play painted the cell red). The score and the % are the yardstick; each hand's bb is still in the list, as information.
How to use it (step by step)
- Open Exploits and click See these hands under "Your next exploit".
- Read Your most repeated mistakes — that's the pattern to fix, not a single hand.
- To go deeper, filter by the flop type where your % is lowest.
- Review a few "Left on the table" hands to see the right line street by street.
- Take the fix to Training and come back after importing more hands to watch the % rise.
Common questions
- Is this GTO? No. GTO plays not to be exploited. Here the yardstick is the real mistakes of the population at your level, so you profit from them. GTO/range study lives in Ranges.
- Where does the score come from? From the exploit engine (the "Blueprint"), which reads each postflop decision in your hands by board texture and compares it with the play that punishes the field. Details in How the Exploits tab works.
- Why don't some spots/flops have a %? Fewer than 20 opportunities. Import more hands.
- Do I need Pro? Yes, it's part of the full Diagnosis.
