Frequently Asked Questions: A5o vs 87o
Who is favored to win between A5o and 87o?
A5o holds the statistical advantage with 56.18% equity and a 55.97% win rate. 87o has 43.82% equity and wins 43.6% of the time, with a 0.43% 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 0.43%. The underdog has a direct win probability of 43.6%, meaning the trailing hand will overturn the favorite roughly 1 in every 2.3 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.
