Build a custom solve

There are two useful starting points in Study:

• From a preflop line: follow the actions until two players reach the flop, choose three cards, and confirm. Use the flop setup's edit control to open Solver Settings.
• Start directly from postflop: use Edit postflop setup in the action line, choose a flop, then review Solver Settings. This creates a postflop setup without requiring you to play through a preflop line first.

Check the positions shown above the two ranges. OOP is the player acting first postflop; IP acts after them. If your target is a turn or river decision, build the starting spot and follow the relevant actions and board cards to that decision. The manual setup begins from the flop.

Work through the settings in this order:

1. Pot: the starting postflop pot, in big blinds.
2. Effective stack: the remaining effective stack at that starting point, also in big blinds. Do not enter the original preflop stack without accounting for money already invested.
3. Rake: choose No Rake or With Rake; if enabled, check the percentage and cap in BB.
4. Player Profile: check how each player is modeled. A profile's postflop behavior is separate from the cards in its starting range.
5. Ranges: inherit from the preflop line when available, or choose and edit range presets. Verify both players, not just your own range.
6. Bet sizes: check each player's options on the flop, turn, and river, including raises and all-ins.

Use range editing and bet sizing for those controls in detail. If an input is uncertain, record the assumption and test an alternative later.

Choose Apply to submit the setup. Wait for the result to finish loading before reading it. A loading or error message is not a completed solve. Solve availability and resource limits follow your account; if a request fails, read the message before retrying the same setup.

Begin at the displayed decision and read the full range's action mix. Select a hand, inspect the exact combinations, then compare their action frequencies and EV where available. Continue the action line to study later decisions.

Check the flop setup notice after an edit. Changing the inputs can disconnect the postflop model from the original preflop line. Later decisions belong to that revised setup.

You can also ask Fisher to prepare a spot in conversation. Review its proposed setup before confirming, then use Open in Study when a result offers it. The Study and Fisher guide covers that handoff.

Reopen Solver Settings to adjust one input. Keep the board, ranges, and other settings fixed when you want to understand the effect of a single change. Setup changes can return you to the start of the postflop model, so navigate back to the decision you want to compare.

The flop setup's Reset custom setup control returns to the original solution context. It is different from Reset to preset inside a range editor and Unlock inside a nodelock editor.

For an opponent tendency at a specific decision, use nodelocking. For an ongoing player model, use profiles. The built-in Compare view appears for supported profile or locked strategies; changing only a pot or range does not automatically create a general comparison dashboard.
