Constructed example 1
Card 1
Heads-up no-limit Hold'em, river. The pot is 60 chips before the opponent moves all-in for 30. You can call the full 30. Ignore rake. What pot-share equity makes calling break even against folding? Show the denominator.
Show answer and reference
Answer. 25%. The final pot after calling is 60 + 30 + 30 = 120 chips; 30 / 120 = 0.25.
Check your response. State 25% and include the call in the final pot. This is a price threshold, not an estimate of your hand's equity or an instruction to call.
Limit. A correct answer to this calculation does not establish the right action against an unknown range.
Try a changed condition
Keep the starting pot at 60 but change the opponent's all-in and your call to 60. You can call the full 60. What is the threshold?
Show variation answer
Answer. One third, approximately 33.33%: 60 / (60 + 60 + 60).
Inspect the original prompt and repair
Original prompt. Why do I need 25% equity against a half-pot bet?
Problem. The question supplies the quantity it is meant to test.
Compare the original with the card front above. The repaired front keeps the information required by its stated question; the answer and reference remain on the back.
Constructed example 2
Card 2
No-limit Hold'em. The button raises preflop, the small blind folds and the big blind calls. Heads-up on the flop, the big blind checks and the button bets. What is the standard name for the button's bet, and which earlier action determines the label?
Show answer and reference
Answer. A continuation bet. The button was the final preflop raiser and then bet the flop.
Check your response. Name the bet and identify the final preflop aggressor. You do not need hole cards or a board to classify this action sequence.
Limit. Naming the bet does not establish that it was strategically good.
Try a changed condition
Keep the same preflop history, but the big blind bets first on the flop, before the button acts. What is that bet called?
Show variation answer
Answer. A donk bet: the prior caller leads into the previous street's aggressor before that aggressor can act.
Inspect the original prompt and repair
Original prompt. The button bets the flop. Is that a continuation bet?
Problem. The action history needed to identify the bet is missing.
Compare the original with the card front above. The repaired front keeps the information required by its stated question; the answer and reference remain on the back.
Constructed example 3
Card 3
Standard Texas Hold'em. Your hole cards are As Qd. The river board is Ks 9s 5s 2s 7h. Name your best five-card hand.
Show answer and reference
Answer. An ace-high flush: As Ks 9s 5s 2s. Hold'em permits using one hole card with four board cards.
Check your response. Name the flush and its five cards. Card notation: s spades, h hearts, d diamonds, c clubs.
Limit. This card asks hand construction, not whether to bet or call.
Try a changed condition
Change the game to four-card Omaha high and your hole cards to As Qd Jh Tc. Keep the board Ks 9s 5s 2s 7h. Can you make a flush?
Show variation answer
Answer. No. Omaha requires exactly two hole cards and three board cards; this hand has only one spade.
Inspect the original prompt and repair
Original prompt. I hold the ace of spades and the board has four spades. Do I have a flush?
Problem. The rules profile is unstated; one spade in the hand is interpreted differently across games.
Compare the original with the card front above. The repaired front keeps the information required by its stated question; the answer and reference remain on the back.

When the card asks for a solver strategy
- Format and positions
- Exact hole cards and board
- Street, action sequence, pot and stacks at a named checkpoint
- Ranges, rake/ante and available bet sizes
- Reference solution identifier, version/date and displayed output
Include only context needed by the target question. A definition card does not need a full solver setup. Keep unverified strategy cards out of the active deck.
Keep the reference identifier on the front neutral if its wording would give away the answer. Put the full source and displayed solution on the back. Preserve mixed actions instead of replacing them with a single forced choice.
