# Poker Academy GTO Postflop Solver > Walk a preflop line, then solve the flop on the same screen. Heads-up flop, turn and river, EV and equity for every combo, and nodelocking to test an exploit. **URL:** https://poker.academy/gto-postflop-solver --- ## What it does Most solvers make you rebuild a spot before they answer. Here the preflop line you just read already carries the ranges, the pot and the stacks. Press Solve Postflop, and the flop solves under the same matrix, next to the same table. - Ranges, pot and stacks arrive from the preflop line - Bet sizes set by stack-to-pot ratio, by hand, or picked by the solver - Flop, turn and river, street by street, heads-up - Lock what your opponent does and see the best response ## In numbers - Heads-up flop, turn and river - Up to 5 bet sizes, 3 raises - Stacks up to 200 bb - EV, equity and EQR for every combo - 0.6% average Nash Distance ## Setting up a spot - **The spot is already set up when you get there**: Walk a line in Browse. Where it closes with two players, the trail offers Solve Postflop. The drawer opens with both ranges, the pot and the effective stack taken from the line, and bet sizes derived from the stack-to-pot ratio. Pick the flop and solve. - **Set up the heads-up spot you want to check**: Open the standalone solver and build the spot yourself. Pick three cards or a random flop. Set each range with a weight slider, a top-percent slider, the 13×13 grid, or paste it as text. Pot from 2 to 200 bb, effective stack up to 200 bb. ## Bet sizes You never draw a game tree. Choose how the bet sizes are set, and the solver builds the tree from that. - **Auto: sizes that follow the stack**: Bet sizes follow the stack-to-pot ratio of each street, so a deep flop and a shallow river get different menus. - **Manual**: Your sizes, sent to the solver exactly as configured, on every street. Optional menus per street. - **Dynamic**: You give candidates; a fast preview solve keeps the one or two sizes with the best EV, then the final solve runs on those. - **How many sizes** (per decision): Bet · up to 5, Raise · up to 3, 3-bet · up to 2, 4-bet and above · all-in - **Solved on our servers**: You set the spot and read the answer in your browser. The solve runs on our servers, so your computer does not need to be powerful. ## Every combo, with what it is worth The 13×13 matrix shows strategy, EV, equity and EQR. Pin a hand and each combo lists its weight, EV, equity and equity realisation. Beside it, the hands rail breaks the range down by hand category, draws and blockers. ## Pick the turn card, solve the turn, then the river From a solved flop, choose the next card and solve the next street. Each street solves on its own, with sizes set again from its stack-to-pot ratio. The runout map shows how every turn or river card changes the picture. ## Say how your opponent plays. See what beats it. Nodelocking starts from an assumption: at this node, this player checks too often, folds too much, or bets too wide. Lock that, re-solve the street, and the solver shows the best response to it and what it is worth. - **Paint the assumption**: Brush a strategy onto hand classes: Check 100% on BTN's weak offsuit hands here, 187 of 1,326 combos. The impact shows before you solve. - **The other player adjusts**: Calculate Exploit re-solves the current street with your locks. The GTO solve is kept; toggle GTO and Exploit to compare. - **Where the response shifted**: Compare lists the nodes that moved most and the EV difference for every hand, in one grid. An exploit answers one assumption. Not sure what to paint? Pick a profile instead. It locks the player acting at the current node to a known leak, in three strengths from a light touch (S) to an extreme one (L), then you re-solve as usual. - **Nit**: Plays mostly strong hands. Hands that are only just worth continuing get folded instead, on this player's first two decisions in a line. Tests: how much you win by betting into someone who gives up too easily - **Bully**: Puts on pressure. Checks that were close to a bet become bets, on this player's first decision in a line. Tests: how you should defend when someone bets too often - **Calling Station**: Does not like folding. Hands that should fold become calls instead, on this player's first two decisions in a line. Tests: how much thinner you can value bet, and when to stop bluffing ## Heads-up, No Limit Hold'em, up to 200 bb - **Three or more players**: Postflop solves are heads-up. When three players see the flop, the trail says so. - **ICM after the flop**: ICM is available on preflop spots in Browse, not in postflop solves. - **Stacks past 200 bb**: Effective stacks go up to 200 bb, pots from 2 to 200 bb. - **Other games**: No Limit Hold'em only. ## Questions **Do I have to build a game tree?** No. Auto sets the bet sizes from the stack-to-pot ratio of each street. If you want control, Manual sends your sizes exactly as you set them, and Dynamic lets the solver pick the best of your candidates. **How accurate is it?** Our engine reports on average 0.6% Nash Distance. A solve is an approximate equilibrium for the tree and sizes you gave it; other sizes give other answers. **Can I solve the turn and river?** Yes, street by street. Pick the next card and solve it. Each street solves on its own, and nodelocking works on one street at a time. **Does it need a powerful computer?** No. The solve runs on our servers and you read it in your browser. **Can it solve pots with three or more players, or ICM after the flop?** No. Postflop solves are heads-up, and ICM is a preflop read. ## Plans that include it **GTO Postflop Solver** - No daily limit: Premium - Solve any heads-up spot: Essential, Standard, Premium - Your own bet sizes (up to 5 per street): Essential, Standard, Premium - Node locking to find exploits: Standard, Premium - Solves run on our servers: Essential, Standard, Premium
