Frequently Asked Questions: K4s vs 87o
Who is favored to win between K4s and 87o?
K4s holds the statistical advantage with 57.66% equity and a 57.31% win rate. 87o has 42.34% equity and wins 42.0% of the time, with a 0.69% chance of splitting the pot.
How does this matchup change on the flop?
Pre-flop equities represent full five-card river run-outs across all 1.7 million combinatorial boards. However, the three-card flop accounts for roughly 71% of a hand's final texture. When the flop brings cards that coordinate with the underdog's holdings (such as straight or flush draws, or hitting an overcard), the trailing hand's equity can surge past 65–75% on the turn.
What is the probability of a split pot or bad beat?
In this exact matchup, the tie probability is 0.69%. The underdog has a direct win probability of 42.0%, meaning the trailing hand will overturn the favorite roughly 1 in every 2.4 showdowns.
How should you play this matchup in tournaments vs cash games?
In deep-stacked cash games (100bb+), position and post-flop implied odds dictate whether calling pre-flop raises is profitable. In tournament play with shallower stack depths (under 25bb), stack-to-pot ratios (SPR) shrink dramatically, making all-in shoves and 3-bet commitments mathematically dictated by pre-flop push/fold equity rather than post-flop maneuvering.
