Hate theory? Love dynamic play?
If so, GM Marian Petrov has a great opening choice for you.
Play the Reti Opening.
It is a low-theory, solid, and very flexible opening.
Most club players don’t expect you to play the Reti.
That means you are getting an instant advantage after move 1.
They expect Reti to transpose to one of the familiar 1.d4, so they can avoid the unknown territory.
That can’t be further from the truth. You’ll still need to be familiar with typical structures and ideas to play it. It’s not a ‘zero theory opening after all.
Time to get started!
