Card examples: test the idea first
These are learning examples, not reported real hands. Enter the cards in Poker Simulator, look at the first result, and then change only one detail.
A♣ J♦ — UTG / BTN
Your cards: A♣ J♦ · Seat: UTG → BTN · Chips in play: 100 BB
In simple terms: Use the cards above to see how the preferred decision changes. The notation at the end is a short mathematical check: n ↓ → |R| ↑
What this teaches: Change one card, bet or opponent hand and compare the new result. A single deal can end either way, so focus on whether the decision made sense before the next card appeared.
7♣ 6♣ — CO / SB
Your cards: 7♣ 6♣ · Seat: CO → SB · Chips in play: 40 BB → 100 BB
In simple terms: Use the cards above to see how the preferred decision changes. The notation at the end is a short mathematical check: EV(CO, 40) ↔ EV(SB, 100)
What this teaches: Change one card, bet or opponent hand and compare the new result. A single deal can end either way, so focus on whether the decision made sense before the next card appeared.
A♣ J♣ / A♣ J♦
Your cards: A♣ J♣ → A♣ J♦ · Seat: HJ · Chips in play: 100 BB
In simple terms: Use the cards above to see how the preferred decision changes. The notation at the end is a short mathematical check: AJs ↔ AJo; ΔEV
What this teaches: Change one card, bet or opponent hand and compare the new result. A single deal can end either way, so focus on whether the decision made sense before the next card appeared.
What this guide helps you do
How to Build Your Own 6-Max Preflop Charts should produce a repeatable process, not a rule copied without context. Separate facts, assumptions, calculation and the final decision.
Build a baseline first, then adjust it for position, stack, previous action and the people still left to act.
Step-by-step method
Work on one clearly defined situation at a time. Record the initial conditions before looking at the answer. Change one variable per comparison, then describe why the result changed in ordinary language.
- Define the exact decision and starting conditions.
- Create a conservative baseline.
- Test a wider and a tighter alternative.
- Save the boundary where the preferred action changes.
Mistakes that distort the result
Do not use a winning hand as proof of a good decision or a losing hand as proof of a mistake. Small samples, incomplete histories and assumptions chosen after the result can all mislead.
Practical exercise
Use Poker Simulator as an independent check of known cards and probabilities. It does not automatically know an opponent’s range, tournament payouts or your personal budget.
Solve ten neighboring situations and mark the first one in which your action changes.
Final checklist
The starting data are complete; assumptions are visible; at least two realistic alternatives were tested; the result can be reproduced; the next training action is written down.
Probability beyond poker
Compare random outcomes with the Roulette Simulator and observe how short samples differ from long-run frequencies.
FAQ
Is this a fixed strategy?
No. It is a baseline that must be adjusted when the format, stack or assumptions change.
How many examples should I study?
Use enough neighboring examples to find the point where the decision changes; one hand is rarely enough.
Can Poker Simulator make the final decision for me?
It checks card probabilities, but strategic assumptions remain the learner’s responsibility.
How do I know that I am improving?
Retest the same skill later without prompts and track accuracy plus the quality of your explanation.
Does a correct decision guarantee profit?
No. Poker contains variance, and responsible limits remain necessary.
