What HydraSolver does

Build a spot, solve it, read it, drill it. Hold’em, Short Deck, 4-, 5- and 6-card PLO, hi-lo, and tournaments, all in one app on your own machine.

Build

Set up a spot in a minute.

Tree Wizard Pick the game, seats, stacks and bet sizes and you have a tree. Change it any time.
Ranges from anywhere Paste or drop ranges from PPT, Pio, GTO+, CSV or plain text. Type top10% or $ds and it just works.
Lock how a player plays Right-click a spot, set what that seat does, and the solver works around it. Great for studying a real opponent.
Postflop from a preflop solve Stop on any spot in a solved tree and start a flop, turn or river solve from it. The ranges come along.
Knows what it will cost See the RAM a tree needs before you press Start, and pick Standard or High detail to fit your machine.
Catches mistakes for you A missing call, a broken stack, an unreachable spot: the app flags it and offers to fix it.

Press Start and watch it get better.

Pause, resume, stop Stop whenever you like and keep what you have. Come back later and carry on from the same place.
Stop when it’s good enough Set an accuracy target or a time limit and walk away. The run finishes itself.
See how accurate it is Exploitability, convergence and every seat’s EV sit across the top the whole time, in plain numbers.
Best Response Pick a seat and attack the rest of the table. You get a ranked list of the biggest leaks, each one a click from its spot.
Lots of boards at once Run one spot across 25, 100 or all 1,755 flops overnight, on one machine or several, and read the results in one report.
Uses every core you have Set the thread count or press All CPUs. Cap the RAM if you want to keep some for yourself.

A strategy browser, not just a grid.

Chart or list The classic 13×13 grid for Hold’em, hand shapes for Omaha, or a sortable list. Colour it by mix, EV or weight.
Filter like you talk Ax, TT+, $ds, top10%. Presets for the everyday ones.
EV for every option See what each action is worth in big blinds, chips, percent of pot or tournament dollars.
Find a line by typing it Ctrl+F, type “check check bet”, and jump straight to it instead of clicking through the tree.
Favourites and notes Star the spots you keep coming back to and leave yourself a note on any of them.
Help that matches the screen A searchable Help Center inside the app, written for the panels you are looking at. F1 opens it.

Play the spots, get graded.

Real hands on a real felt Your cards land on the table, you see the line you are facing, and you pick an action. Then the solver shows its mix.
Graded on what it cost A miss is scored by the EV you gave up, not just right or wrong. Strict or loose on bet sizes, your call.
Redeal your misses Play the hands you got wrong again until they stick. Roll the mix when a spot is a coin flip.
Keeps score over time Sessions save themselves. See where the EV goes by street and by seat, and export it if you want.

One engine for every game you play.

Seven variants No-Limit Hold’em, Short Deck, 4-, 5- and 6-card PLO, and 4- and 5-card hi-lo (Big O). Up to nine seats. No-limit, pot-limit or fixed-limit.
Bomb pots and double boards Ante everyone and go straight to the flop. Deal two boards and split the pot, solved properly rather than guessed.
Stand Up (Nit) Game and Squid The side money is in the EV, so you see how these games really change your ranges.
Rake, straddles, antes Rake presets for online and live games. Straddles and double straddles. All priced into the solve.

Chips aren’t money. Solve for the money.

ICM and Future Game Switch from chip EV to ICM and the strategy changes. Future Game looks a few hands ahead, so a double-up is worth what it is really worth.
Bounties Progressive knockouts, fixed bounties and mystery bounties, with the bounty money in every decision.
Any payout structure Type it, import it, or generate one from field size and percent paid. Final table or a big field on the bubble.
See the pressure Bubble factors and risk premiums for every pair of seats, so you know who can’t afford to call.

Keep it, share it, take it anywhere.

Save and resume Save a run, reopen it later and keep solving. Or save a small snapshot when you only want to read it.
Open it in your browser Export a street and open it in HydraViewer on any laptop or phone. Nothing to install.
Works with other tools Ranges out as PPT, Pio, CSV or your own format. Whole streets as text or JSON. Strategy pictures as PNG.
Buy solves you’d rather not run The HDS Shop sells finished preflop solves for every game, ready to open and ready to build postflop from.
