Your Edge — Even When Chess
Engines Show Triple-Zeroes!

Your opponent is a tough nut to crack. The position — dead even. But hidden in there is one line which gives you a serious chance of winning. How do you find it? You unbalance the pieces! Because when your pieces differ from theirs, you open up plans the other side can’t copy nor stop.

Did you end up with the two bishops against a bishop and knight?

Right away, you hold the upper hand in an opposite-side race to promotion.

Black’s knight is too far to assist their pawns, while
your bishops don’t even have to move to delay
the enemy advance AND support yours

Only have a rook against a bishop and knight?

That means you can attack their 7th or 8th rank in one swoop… while they maneuver for 2 or 3 moves before they can even threaten anything.

The rook can create threats faster than

And when you’re fighting a queen with a bunch of light pieces?

You hit their weak pawns, weak squares, and even the opponent’s strongest piece… because they wouldn’t dare trade their 9 points for your 3 points.

Don’t worry if it all seems advanced right now. You can learn how to unbalance the pieces, and turn those matchups into a decisive edge.
