Frequently Asked Questions

• What is the rule of 2 and 4 in poker? ▼
  After the flop with 2 cards to come, multiply your outs by 4 for an approximate win percentage. After the turn with 1 card to come, multiply by 2. Example: 9 flush outs × 4 = 36% on the flop.
• What are pot odds? ▼
  Pot odds = call amount / (pot + call). If pot is $100 and you must call $20, pot odds = 20/120 = 16.7%. If your win probability exceeds pot odds, calling is profitable.
• How many outs does a flush draw have? ▼
  A flush draw has 9 outs (13 suited cards − 4 already seen). An open-ended straight draw has 8 outs; a gutshot has 4 outs.
• What is implied odds? ▼
  Implied odds account for future betting: the additional money you expect to win if you hit your draw. They make calling correct even when pot odds alone are insufficient.
• What is fold equity? ▼
  Fold equity is the probability your opponent folds to a bet or raise. Semi-bluffing combines fold equity (win now) with equity from your draw (win later if called).
