Poker Shark
See the range you're up against. On every street, as it develops.
Shark Vision reads each opponent's line and shows the range they are likely holding, so you can stop guessing at one hand and start playing against everything they can actually have.

Why hand reading is the skill that separates winners
The players who beat cash games are not guessing. They read the range, adjust every street, and put their opponent on a set of hands instead of one. It is the same read the six opponent types reward, and the core idea behind exploitative poker strategy. Here are the three problems a real range read solves.
The guessing problem
Most players put an opponent on one hand and play against that. When the guess is wrong, they stack off or fold the best hand. A real read is about the whole range, not a lucky pick.
The static-range problem
A range is not fixed. Every street, the bets and checks narrow what your opponent can have. A read that does not update as the hand develops is already stale.
The results problem
You called and they had it, so the call must have been bad. Not necessarily. Against their range, the call can be correct even when this one card falls wrong. Reading ranges separates the decision from the result.
How Shark Vision reads a range, street by street
Shark Vision is the in-hand read panel. It turns the opponent's actions into a live picture of the hands they can hold.
Start from the archetype
Every opponent is one of six player types, each modeled on real cash-game data. Before a card is dealt, Shark Vision knows the hands that type tends to play and how they play them.
Narrow on every action
A limp, a 3-bet, a turn barrel: each one removes hands that would have played differently. The range on screen tightens to fit the line they have actually taken.
Weight by how they play
Not every hand in the range is equally likely. Shark Vision weights the range by how often that type shows up with each holding, so you see where the mass really sits.
Act on what's there
Now the decision is simple. Size your value bet to the hands that call, pick off the bluffs their line still contains, or fold when the range has you crushed.
What the range tells you on each street
Reading a range is a habit you build one street at a time. When the question is whose range hit the board harder, the range advantage calculator answers it for any flop.
Preflop
- How wide does this position and action open them up?
- Are they capped without a 3-bet?
- Which suited and connected hands survive their line?
Flop
- Does this texture connect with their range or miss it?
- How much of their range is draws versus made hands?
- Are they betting the whole range or only the strong part?
Turn
- What did the turn add to their range?
- Do their bluffs still have equity, or did they whiff?
- Has the second barrel narrowed them toward value?
River
- What value hands and busted draws are left?
- Is this a spot to bluff-catch, thin value bet, or fold?
- Which sizing gets called by the most worse hands?
Reading by feel vs reading with Shark Vision
Reading by feel
- Put them on one hand
- Freeze the read after the flop
- Hope the guess was right
- Blame the card when it is wrong
Reading with Shark Vision
- See the whole range
- Watch it narrow on every street
- Size to the range, not a guess
- Separate the decision from the result
The difference is that you are no longer guessing at one hand. You play against everything they can have.
Questions about reading ranges
How do you read a poker player's range? +
Start from how that player type tends to play, then narrow as the hand develops. Each action they take (a raise, a call, a check) removes the hands that would have played differently. Shark Vision does this narrowing for you, showing the range that fits the line they have taken so far.
Can Poker Shark see my opponent's actual cards? +
No. Shark Vision shows an estimate of the range a player is likely holding, built from how that opponent type behaves, not their exact two cards. The point is to train you to think in ranges instead of guessing at one specific hand.
What is a range in poker? +
A range is the full set of hands a player could have in a spot, not a single holding. Strong players think about the whole range an opponent can show up with, then pick the action that does best against all of it.
How is this different from a GTO solver? +
A solver assumes a perfect opponent. Shark Vision is built from how real player types actually behave, so the range it shows reflects the habits and leaks of the opponent in front of you. That is what lets you exploit them instead of only playing balanced.
