Why PokerSharp starts with learning
The first poker I ever played was in a staff room, with a deck somebody kept on top of the microwave. End of a double shift, four of us too wired to go home, playing for pride and the last of the coffee. I lost. Not in a dramatic way. Just steadily, for a long time, while being quite sure I was getting better.
That is the trap, and it took me years to see it. Poker is the best decision trainer I know, and also the worst teacher. You never have all the information. The right move loses all the time. And when you call a big bet with a bad hand and the river bails you out, the game pats you on the head and says: well done, do that again. So you do.
PokerSharp exists because I wanted someone to tell me, right then, "that call was bad, and here is why", before the pot had a chance to lie to me.
Learn the decision. Practice at the table. That's the whole idea.
What we're building
The app runs on an iPhone, and that matters, because the staff room is where I had five spare minutes, not a desk. But the thing I actually want to build is a crowd of people who like thinking and are happy to use a hard, slightly cruel game to get better at it.
Because poker keeps rewarding the habits that are rare everywhere else. Pot odds are arithmetic with someone staring at you. Position is patience: waiting until it's your turn to have the advantage. Reading a board is pattern recognition. Folding a hand you've already fallen for is self-control with a clock running. And looking at your own mistakes without flinching? That one is the hardest, and it's the one that compounds.
So the order inside the app is the order a person can actually absorb. A short lesson explains one decision. A drill makes you use it, with cards that change every time, so you learn the method instead of memorising the answer to one hand. Then a full table, with opponents who don't wait for you, to find out whether the habit survives pressure. Mine often didn't. That is exactly what practice chips are for.
What the app knows, and what it doesn't
A lot of poker software talks like it has seen your opponent's cards. It hasn't. Neither have we.
When PokerSharp shows you an equity number, it shows the assumptions underneath it. When it leans towards a call, it calls that a model estimate, not the truth. When a spot is close, it says "close" instead of picking a side and sounding confident. It assesses only what it has taught you, and it never pretends to know what the other player is holding.
I'd rather you occasionally argue with the app than trust it blindly. Blind trust doesn't come to the table with you. Judgment does.
Why there's no money in it
Learning needs a safe table. In PokerSharp the chips are practice chips. No deposits, no prizes, nothing to lose except a habit you'd be better off without. You can make the call you'd never risk, watch it go wrong, read why, and run the same idea again with fresh cards. Every other skill gets learned that way. Poker got stuck with "pay for your lessons", and we'd like to unstick it.
What comes next
Version 1.1 shipped on 7 October, and it carries the piece I wanted from day one: a notebook. Every time you make a decision the app disagrees with, it goes in there with the cards and the reasoning. From the notebook you practise that exact kind of spot with new hands, and a weekly report tells you, plainly, whether the mistake is going away or just hiding.
After that, the roadmap is yours as much as mine. Tell us where you're stuck. Tell us where an explanation lost you. We read every message, usually late at night, which is when this app has always been built.
John writes under the handle Dev «Esc hospitality» John, and the middle part is the plan. He learned poker in staff rooms and after-shift games, got serious about the maths, and built PokerSharp on night shifts and days off: an iPhone app that teaches Hold'em one decision at a time, with short lessons, drills at a simulated table and the arithmetic behind each spot.
