What it measures
WWSF is the broadest postflop result stat. Take every hand where the player saw the flop and ask one thing: did they win money? It doesn’t care how. A river call that was good, a c-bet nobody called, a check-raise that took it down and a chopped pot all count the same.
That makes it a measure of how well a player fights for pots after the flop. Players who give up when they miss win fewer of their flops. Players who keep betting win more of them, often without the best hand.
It overlaps with two showdown stats. Went to showdown is how often they get to the end; won at showdown is how often they win once there. WWSF adds the pots won with no showdown at all. It isn’t a profit stat, since winning lots of small pots and losing the big ones is a losing pattern, and it isn’t flops seen, which is how often they get to a flop in the first place.
How it’s calculated
WWSF = hands won after seeing the flop ÷ flops seen.
- A chance: every hand where they saw the flop.
- It counts: when they won money in the hand, with or without a showdown. Chops and side pots count as wins.
Every win comes either at showdown or without one, so WWSF splits cleanly in two. The showdown part is WTSD × W$SD; the rest is pots won when everyone else folded.
Example: Gina saw 80 flops. She reached showdown 24 times (WTSD 30%) and won 12 of those (W$SD 50%), so 12 of her 80 flops, 15%, were won at showdown: 30% × 50%. She also won 24 pots when everyone folded. WWSF = (12 + 24) ÷ 80 = 45%, and 30 of those points came without a showdown. If she stopped betting when she missed, that second part would shrink, and her WWSF with it.
The HUD keeps a single version of WWSF, with no splits by position or pot type.
Why it matters
WWSF tells you who wins the pots that nobody has much of a hand in. Most flops miss most hands, so a big share of postflop pots go to whoever is willing to bet for them. A player with a high WWSF takes those; a player with a low one hands them over.
The table you play changes the baseline. When two players see a flop, one of them wins it (a chop gives both a win), so across heads-up flops the average is a little above 50%. Every extra player on the flop lowers it: in three-way flops the average is close to a third. PokerNow home games with lots of limped, multiway flops pull everyone’s WWSF down, so compare a player with the rest of the table, not just with 40–52%.
It matters most when you decide whether to attack or respect a player after the flop: whether to c-bet, stab and probe them, or call their bets lighter. Read it with their fold to c-bet and aggression factor, which show where the wins and losses come from.
Too low, about right, too high
Too low: under 40%
What it says
They give up too many pots after the flop. The usual pattern is fit-or-fold: they call preflop, miss, and fold to the first bet, or check and let you take it. A high fold to c-bet and a low AF often come with it. A low WWSF can also come from playing lots of multiway flops, where everyone’s share drops, so check how many players they usually see flops against before you call it a leak.
How to exploit it
- C-bet them with most of your range on dry boards, using a small size: 33% of the pot needs only 24.8% folds to profit as a pure bluff.
- When you’re in position and they check, bet. Their checks are mostly give-ups.
- When they raised preflop and checked back the flop, lead the turn with a probe bet: they rarely fight back.
- Don’t pay them off when they do fight. A low-WWSF player who raises, or bets three streets, is usually strong.
About right: 40–52%
What it says
They win about their share of postflop pots. That can come from a sound mix of showdown wins and pots taken by betting, or from two leaks that offset each other, such as calling too much while also bluffing too much. The total hides that, which is why the split matters more than the number.
How to exploit it
Split it with the formula above. If most of their wins come at showdown, they’re a caller: value-bet them and bluff less. If most come without showdown, they’re a bettor: check medium hands to them, call down lighter and check-raise more. For example, with WTSD 34% and W$SD 50%, showdown wins are 17% of their flops, so a 46% WWSF leaves 29% won without a showdown: a player who takes plenty of pots by betting.
Too high: over 52%
What it says
They win more than their share of postflop pots. Usually that’s aggression: they c-bet, barrel, stab and raise until opponents give up, and a high AF backs it up. Sometimes it’s a tight player who only sees flops with strong hands, mostly heads-up. Short samples run hot too: at 30 flops the error around 50% is about ±9 points.
How to exploit it
- With a high AF: fold less. Call their c-bets and turn bets wider with pairs and draws, and check-raise strong hands and good draws.
- Check medium-strength hands to them and let them bet into you, rather than leading.
- Bluff them less after the flop. Players who win this many pots fight back.
- With a low VPIP instead: respect their bets. Their wins come from strong hands, not pressure.
When it’s your own number
WWSF never makes a read, on your badge or anyone’s, but opponents who study your numbers can still see the pattern. A low WWSF says you give up pots: expect more stabs and probes when you check, and more barrels when you call. A high one says you fight for pots: expect more check-raises and lighter calls.
To check yours, split it into the showdown part (your WTSD × W$SD) and the rest. If the non-showdown part is small, you’re probably folding or checking too much after you miss, so c-bet and stab more on dry boards. If it’s very large, make sure your W$SD isn’t sinking from bluffs that get called.
Using it on the HUD
WWSF is in the player database only: it isn’t on the table badges or in the panel. Open the player database page to see it with every other stat for that player, against the same 40–52% typical range. There are no narrower versions, and it has no read hint, so it never turns into a read sentence.
Sample size: chances are flops seen, so it fills up as fast as WTSD. Around 50%, the error is about ±9 points over 30 flops and ±5 over 100, and a player who sees a flop every third hand needs about 300 hands for 100 flops. Use it as background when you review a player away from the table, together with WTSD, W$SD and AF.
Questions
What is WWSF in poker?
WWSF stands for won when saw flop: the percentage of hands where a player saw the flop and then won money, with or without a showdown. It measures how often they end up with the pot after the flop, whether by holding the best hand or by making everyone else fold.
What is a good WWSF percentage?
The HUD’s typical range is 40–52%. Solid aggressive players tend to sit in the upper half, because they win pots without showdown. Under 40% often means giving up too easily. Multiway flops pull everyone down, so in loose home games a number near 40% is less worrying than it would be in mostly heads-up pots.
WWSF vs W$SD: what’s the difference?
W$SD counts only showdowns: of the hands that reached showdown, how many they won. WWSF counts every flop they saw, including pots won when everyone folded. A player can have a high W$SD and a low WWSF by folding too often before showdown, or a high WWSF with a low W$SD by bluffing a lot.
Why isn’t WWSF on the HUD badges?
The badges focus on stats tied to the spot in front of you, such as fold to c-bet when you’re about to c-bet, while WWSF sums up every postflop spot at once. You’ll find it on the player database page, with every other stat for that player.
