About the Glek Defense

The Glek Defense puts the queen's knight on a6 with 7...Na6 rather than the main-line 7...Nc6. The rim square looks awkward, but once White plays d5 the knight reroutes to c5, and it also guards c7 if Black plays ...Qe8. White's main replies, 8. d5 and 8. Be3, are about equally popular, with 8. Be3 Ng4 9. Bg5 Qe8 a common sequel. 8. Re1 scores best for White in practice, and engines rate White's position as clearly better.
