Why I built jarvispoker: the $2,000 lesson that became a study tool

I go by AcePoker. Over the last three years I am up about $20,000 playing poker, most of it from home games and online cash. That number is not the story. The story is the $2,000 I lost before any of it, and what climbing out of that hole taught me about how players actually improve.

It started with $10 home games

I learned poker the way a lot of people do: home games in high school with $10 on the table. Nobody at that table knew what a range was. We played too many hands, chased every draw, and called it reading souls when a bluff got through. It was cheap tuition and it was fun, which is exactly what poker at that level should be.

The problem is that the habits you build at $10 stakes follow you when the money gets real.

The $2,000 hole

When I started playing for stakes that mattered, I ran into a losing streak and did what most new players do: I chased it. Over multiple sessions I tilted off about $2,000. Not in one dramatic night, which would at least make a better story, but in a slow drip of forced sessions, oversized calls, and revenge pots against players who were not thinking about me at all.

Tilt gets described as an emotional problem, and it is. But looking back, mine was mostly a knowledge problem wearing an emotional mask. Hand by hand, I could not tell whether I was making good decisions and running bad, or making bad decisions and blaming luck. That doubt is what tilt feeds on. When you cannot tell variance from error, every lost pot feels unfair, and unfair feels like a reason to play looser, longer, and worse.

What changed

What pulled me out was not a heater. It was switching from replaying grievances to reviewing hands. After sessions I would go back through the spots that stung, reconstruct them honestly, and try to work out what the right play actually was, not what would have won.

Two things happened. My game improved, and the stakes escalated as the winning did. But the second effect mattered more: the doubt went away. Once I could look at a lost pot and say with confidence "that was a correct call that lost" or "that was a mistake, here is why", losing stopped triggering the spiral. Variance became boring. Boring is exactly what you want variance to be.

If you want the full routine, it is written up in study, do not play. It is the single highest-leverage habit I know of in poker.

Why I built jarvispoker

The review loop that fixed my game was clumsy. Photos of hands sat in my camera roll for weeks. Reconstructing a spot meant scribbling stacks and positions into a notes app, then trying to reason about ranges with nothing but instinct and a few charts.

What I wanted was simple: take the photo I already had, get the spot reconstructed, and see what the math says, so I could compare it against what I actually did. That tool did not exist in a form a recreational player would use, so I built it.

That is jarvispoker. You upload a photo of a hand, confirm the cards and the action, and get a solver-backed answer with equity and reasoning attached. The engine behind it is an open-source DCFR solver running on precomputed spots, the same math behind the preflop charts and the rest of the learning section. For the everyday decisions between big pots, the pot odds calculator covers the foundations.

What it is and is not

jarvispoker is free and needs no account. It is built for the calm after the session, not the pressure during it. It is a study and review tool, never live-play assistance. Using solver outputs during real-money online hands breaks every regulated site's rules and gets accounts banned, and it also skips the entire point: the goal is better instincts at the table, and those are built in review.

I still play. The tool exists because I still make mistakes, and I would rather learn from them for the price of a photo than for $2,000 a lesson.

Bottom line

I lost $2,000 learning that tilt is what happens when you cannot tell your mistakes from your bad luck. Reviewing hands honestly is what fixed it, and jarvispoker is that review loop turned into a tool: photograph the spot, reconstruct it, check your instinct against the math, and carry one lesson back to the table. Start with the hand that stung most this week and run it through the analyzer.
