THE FRENCH DEFENSE · STUDENT PLAYS WHITE

1. e4 e6 2. d4 d5 3. e5

GRANDMASTER PLAN

Advance with 3.e5 to claim space — then support d4 and build on the kingside.

The question you're already asking

Why not just chess.com or lichess?

Explorers and puzzle sets are where your students already are. Three things they can't do there:

Get the plan, not the percentage

There
The explorer says 3.e5 scores 52% over 80,000 games. Why it's good — and what to do next — is your student's problem.

Here
The coach plays the line, explains the idea at every branch, then hands over the position and grades what they do with it.

Stay graded off-book

There
Repertoire tools drill one move order. The first unexpected reply and the script ends — feedback arrives after the game, if at all.

Here
Off-book moves get a verdict mid-drill: the idea, the score, and the punishment line played out when it's wrong.

Pin a bot to your repertoire

There
Bots play whatever they like. You can't make one defend the French all evening at your student's level.

Here
Pick the opening and the strength — from Pigeon (~600) to Eagle (~2000). The bird stays in book, and every move gets assessed.

Counter Lab — nothing like it anywhere

An opponent that cheats on purpose

Every opening has known slips — the natural-looking moves that quietly lose. Counter Lab plays the opening correctly… until it doesn't. Nobody tells you when.

Learn its tricks. A guided lesson walks the line and stops at every trap: see the slip, play the punishment.
Then face it live. The slip comes without warning, mid-line.
Spot it. Punish it. Engine-verified refutations, graded move by move — near-misses count.

Enter the lab

They played h3?! — your move.

✓ Found it — that loosened the kingside.

Punished: Qg5 g4 Bxg4

The referral program

What you teach, they practice — and you get paid

One vanity code. Your students get structured practice between lessons; you get a recurring share of every subscription you bring in.

You earn25%of every payment your students make, for their first 12 months. Founding partners earn 30%.

They save15%off Pro for their first 12 months, just by joining with your code.

You getPro, freefor as long as you're an active partner. It costs you nothing.

You're paidMonthlywhenever your balance reaches $50 — from invoices your students actually paid.

Your 25% is calculated on what the student actually pays — the list price minus their 15% code discount. Worked through:

Monthly student: $7 list − 15% = $5.95 paid → 25% of that = ≈ $1.49/month to you (≈ $17.85 over their first year).
Yearly student: $49 list − 15% = $41.65 paid → 25% of that = ≈ $10.41 to you in one accrual.
A 20-student club → ≈ $200–350 over the year, depending on the monthly/yearly mix — for sharing one code.
