      "before": "Why do I need 25% equity against a half-pot bet?",
      "front": "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.",
      "answer": "25%. The final pot after calling is 60 + 30 + 30 = 120 chips; 30 / 120 = 0.25.",
      "grade": "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.",
      "boundary": "A correct answer to this calculation does not establish the right action against an unknown range.",
      "variation": "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?",
      "variationAnswer": "One third, approximately 33.33%: 60 / (60 + 60 + 60).",

      "front": "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?",
      "answer": "A continuation bet. The button was the final preflop raiser and then bet the flop.",
      "grade": "Name the bet and identify the final preflop aggressor. You do not need hole cards or a board to classify this action sequence.",
      "boundary": "Naming the bet does not establish that it was strategically good.",
      "variation": "Keep the same preflop history, but the big blind bets first on the flop, before the button acts. What is that bet called?",
      "variationAnswer": "A donk bet: the prior caller leads into the previous street's aggressor before that aggressor can act.",

      "variationAnswer": "No. Omaha requires exactly two hole cards and three board cards; this hand has only one spade.",
