King's Indian: Glek, 8.Re1
King's Indian: Glek, 8.Re1
Definition
The Glek System with 8.Re1 is a sub-variation of the Main Line of the King’s Indian Defense (KID). After the classical sequence 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6, White develops the rook to e1 on move eight instead of the more common 8.d5 or 8.Be3. This rook move was popularized in the 1990s by the creative Russian GM Igor Glek, from whom the system takes its name.
Typical Move Order
The most common entrée into the Glek System is:
- 1. d4 Nf6
- 2. c4 g6
- 3. Nc3 Bg7
- 4. e4 d6
- 5. Nf3 O-O
- 6. Be2 e5
- 7. O-O Nc6
- 8. Re1 (The Glek move)
Black’s replies are varied—8…exd4, 8…Bg4, 8…Re8, or 8…Nh5 are all well-tested.
Usage in Play
• White postpones the typical central advance d4–d5, keeping tension and flexibility. • The rook on e1 supports an eventual e4-e5 push and overprotects the e4-pawn. • Black must decide whether to clarify the center immediately (…exd4) or to continue with typical KID kingside play (…Nh5, …f5).
Strategic Significance
- Prophylaxis against …Bg4: By putting the rook on e1, White frees the f3-knight to potentially jump to g5/h4 without worrying about the pin …Bg4.
- Delayed d4–d5: White keeps Black guessing. If Black closes the center incorrectly, White can switch to queenside expansion with b4 or a quick c4-c5.
- Flexible pawn breaks: Depending on Black’s setup, White can choose between e4-e5, d4-d5, or even c4-c5.
Plans and Ideas
For White
- Prepare e4-e5, gaining space and opening the e-file for the rook.
- If Black captures on d4, recapture with the knight (c3xd4) to centralize and seek a small initiative.
- Launch a queenside minority attack: a2-a3, b2-b4, c4-c5.
For Black
- Play …exd4 followed by …Re8 and …Bg4, exploiting the pin on the e-file once the rook stands opposite White’s king.
- Opt for traditional KID play with …Nh5 and …f5, generating a kingside pawn storm.
- Counter in the center with …d6-d5 if circumstances allow.
Historical Context
Although the move 8.Re1 had been tried sporadically since the 1960s, it was Igor Glek who made it a regular feature of top-level practice. His victories with the line—particularly against strong KID devotees in the 1990s—drew attention to its practical value as a surprise weapon. Today it remains a respected, if less common, choice for players seeking to sidestep the dense theoretical thickets of 8.d5 or 8.Be3.

Interesting Facts & Anecdotes
- Igor Glek once joked that he adopted 8.Re1 because he “wanted a rook to look his opponent’s king in the eye as early as possible.”
- In the online blitz era, the move has picked up renewed interest: the quick rook activation works well in time-scrambles, where the subtleties of the main lines are harder to recall.
- Top engines show a slight, stable plus (≈+0.20) for White in many branches, suggesting the line is objectively sound yet still leaves Black rich counter-chances—exactly the recipe that keeps it alive in master practice.
