If you want to consistently:
💯 Reach a position of strength with a safe king, and play for the win however the game starts…
💯 Stay in control and confident of your next move — even when the game leaves your prep…
💯 And become a sharper tactician and strategist whenever you drill openings…
Then you’ll love 100 Repertoires: A Complete Black Repertoire.
This complete guide to playing Black checks all of the boxes in just 100 variations. It’s the 10th Chessable course by the prolific International Master Yuriy Krykun…
And it follows a simple plan for success:
Play “easy to remember” moves to carve out a healthy position and an iron-clad bunker for your king.
Secure lasting positional assets instead of betting on short-lived attacks.
Then build your advantages up to critical mass!
Take 1.e4, for example.
Krykun counters the king’s pawn with the …Qd8 Scandinavian. Because with 1…d5, you’re all but guaranteed to arrive at positions you know better than White.
Then, he continues with a fresh …g6-setup which shelters your king in a fianchetto… semi-automates your next 5 to 6 moves… and intensifies the pressure along the diagonals.

This …g6 Scandinavian can whip up a storm
against White’s most natural moves
Against 1.d4, Krykun counts on the airtight Tartakower-Bondarevsky-Makagonov (TMB) variation of the Queen’s Gambit.
World champions, like Garry Kasparov and Magnus Carlsen, love the TMB for good reason.
It stakes your claim in the center with …d5 and …c5 — exchanges a pair of pieces or two to reduce White’s attacking potential — then plays for a queenside pawn majority, where every exchange pushes you closer to victory!

With a fast-advancing queenside majority,
an unstoppable black passed pawn
is just around the corner!
Now here’s the neat part:
Both Plans Are Effective
against Everything Else!
Facing 1.Nf3, 1.c4, or 1.b3? Simply follow the same TMB formula… and you might find that it works even better against flank openings!

The same …d5 and …c5-push — but
against the Reti, they translate to a sizeable
space advantage and piece pressure
If you run into the likes of 1.f4, just fall back to our trusty …g6-setup, and attack the queenside as usual.

Swap the light-squared bishops. Stabilize
the center. Bullrush the queenside
with pawns. Profit!
With Krykun’s unified openings, studying one enhances your understanding of the others. So memorizing variations becomes easier as you progress through the course.
Now that’s just one perk of having him as your coach.
If you’re hearing about him for the first time, he’s a first-class opening theoretician. One who has contributed to major chess publications like New In Chess, and ironed out the repertoires of many top 100 grandmasters.
But what Chessablers love most about Krykun is:
His ability to pass master-level chess understanding with the fewest variations possible.
This superpower earned Krykun multiple award nominations — plus over 1,700 star-studded ratings from happy Chessable members.
Don’t Just Memorize But Understand!
“What makes Yuriy’s courses so great is the fact that he will not make you memorize hundreds or thousands of lines. But rather he will teach you the openings and help you understand the general ideas and plans in a very accessible way. Being one of the top-rated coaches on Lichess, Yuriy has a lot of experience teaching club players, and it really shows.”
— Marsalkka
