How these drills use ranges, blinds and rake
Your opponent is dealt a hidden hand from a weighted range. Captured preflop actions use NL25 screenshot frequencies. WASM mode solves a configured heads-up postflop tree on this device. Approximate practice remains a separate option. Study-board drills begin after the selected opener raises and BB calls, using the matching captured preflop ranges; article charts remain separate references. Solved reviews show action EVs against the calculated average opponent. They are limited to the configured tree and captured starting ranges. 100 bb stacks before blinds. Non-blind openers face BB with a dead 0.5 bb SB contribution. SB–BB drills start after SB opens to 3.5 bb, with both blinds in play. Cash practice applies a fixed 5% rake, capped at 10 bb, after uncalled bets are returned. No rake when the hand ends before the flop. This is a study preset, not a verified match of CoinPoker’s current selective preflop fees; its published full-table NL10 cap was used as a reference. Captured NL25 preflop mixes retain their source settings and have not been re-solved for this preset. Cash practice hides source action EVs because the source rake is unconfirmed.
Preflop uses captured charts. Solving starts at the flop.
One solve covers the configured future tree; later decisions reuse it. Hints stay hidden until answering. Zero-frequency paths and missing charts stop explicitly. Cash solving uses continuous 5% rake; actual payouts round rake down to 0.01 bb. Engine source and license.

Complete hand history
Opponent decisions use its own hand, the visible board and your inferred range. They do not inspect your actual hidden cards or undealt board cards. Opponent cards are revealed only at showdown. Reviews state whether they came from a solved restricted tree or the separate approximate policy.

Width = action frequency. Height = the current arrival estimate; new-chart weights follow prior actions. Black space in the source image is not folding. The compact list omits visibly absent hands while retaining reached hands that should fold. Suit-specific frequencies were not exported.
Export or study a branch
River sandbox: use the branch as a starting assumption, set the river board/pot/stacks, and edit ranges to reflect earlier streets. Sending a range does not solve the missing flop and turn.
Coverage is explicit
Five openings and 30 captured response decisions, including UTG/HJ/CO/BTN/SB versus BB paths, BTN versus SB, and the original SB limp branch. All can be inspected and exported to the river inputs as preflop study ranges.
Other formations, cold-facing an open plus another player’s 3-bet, and uncaptured branches remain unavailable. A blind’s calling options depend on its exact prior actions and source tree; there is no blanket “blinds cannot call” rule. cEV screenshots are not mixed into this library. This is a reference library, not a six-player preflop solving engine.
THE READING ROOM
Build understanding, one idea at a time.
63 concise source summaries, organized for Cash and Tournament study. Shared concepts appear in both. Each article keeps its original game context.
Summaries and study notes are available offline after “Offline files ready”. Original articles open online. These are contextual lessons, not verified strategies for your current hand. Tournament study includes MTT, Spin and heads-up SnG examples; check the source context before applying them.

Filters describe topics and examples mentioned in the saved summaries. Unlisted settings remain unknown; a depth or position tag does not mean every example uses it. Shared concepts retain any cash or tournament examples in their source notes. Search “cEV”, “ICM”, a board or an action sequence for more detail.
