After 55...Qf2+, Grünfeld's early hypermodern counterplay has become a winning attack against Alekhine.
Example sequence: 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Bg5 Ne4 5.cxd5 Nxc3 6.bxc3 Qxd5 7.Nf3 Bg7 8.e3 c5 9.Bb5+ Bd7 10.c4 Qe4 11.O-O Bxb5 12.cxb5 Nd7 13.Rc1 b6 14.Qb3 h6 15.Bh4 O-O 16.Rc4 Qe6 17.Rd1 Rfe8 18.d5 Qd6 19.Bg3 e5 20.dxe6 Qxe6 21.Rd6 Qe7 22.Ra4 Nf8 23.Qd5 Rad8 24.Nd2 Rxd6 25.Bxd6 Rd8 26.Nc4 Qd7 27.h3 Ne6 28.Qe4 Bf8 29.Bxf8 Qd1+ 30.Kh2 Qxa4 31.Be7 Re8 32.Bf6 Ng7 33.Qd3 Qxa2 34.Bb2 Re6 35.Qc3 f6 36.Qd3 h5 37.e4 Qa4 38.Nd6 Qb4 39.Nc4 Qxb5 40.f4 Qc6 41.e5 f5 42.Nd6 Re7 43.Qg3 Kh7 44.Qg5 Qd7 45.Qg3 Ne6 46.Qf3 b5 47.Qa8 Qd8 48.Qd5 b4 49.g3 a5 50.Qc6 Qd7 51.Qa6 a4 52.Ba1 a3 53.Qc4 Qc6 54.Kg1 Qf3 55.Kh2 Qf2+.
2. Kostic 1922: long-term Grünfeld pressure
With 55...Rb2, Black's queenside majority and active rook show how a hypermodern opening can convert later.

Study Grünfeld to understand opening theory before engines, early hypermodern centre pressure and Queen's Pawn development. His games connect historical opening preparation with practical play. Use the lesson finder and choose Grünfeld Defence origins.
What is Ernst Grünfeld best known for?
He is best known for the Grünfeld Defence, reached after 1.d4 Nf6 2.c4 g6 3.Nc3 d5. The opening challenges White's centre with piece pressure rather than immediate occupation. Use the Alekhine and Kostic diagram cards.
Did Ernst Grünfeld invent the Grünfeld Defence?
Grünfeld introduced the defence in tournament play in 1922 and became its namesake. He used the idea against strong opposition soon after, including the famous Alekhine game in Vienna. Use the Grünfeld Defence origins replay group.
What was the first Grünfeld Defence game?
The usual historical reference is Grünfeld's 1922 use of the defence at Bad Pistyan against Friedrich Sämisch. This page's supplied replay set includes related early Grünfeld Defence examples against Alekhine and Kostic. Use the origins group.
What does the Alekhine game teach?
Alekhine vs Grünfeld, Vienna 1922, teaches the core hypermodern idea: allow White a centre, then undermine it with piece pressure, breaks and queenside counterplay. Use the Alekhine diagram after 55...Qf2+.
What does the Kostic game teach?
Kostic vs Grünfeld, Teplitz-Schoenau 1922, teaches long-term Grünfeld endgame pressure. Black exchanges into a structure where the queenside majority and active rook decide. Use the Kostic diagram.
What does the Bogoljubov miniature teach?
Grünfeld vs Bogoljubov shows that the opening theorist was not just a dry technician. He could punish king exposure quickly with central pressure and a mating finish. Use the Bogoljubov diagram after 19.Rd8#.
Was Grünfeld mainly an opening specialist?
Yes, his reputation is strongly tied to openings, writing and theory. He also had serious tournament results, but the page value is greatest as an opening-pioneer study. Use the related Grünfeld Defence card.
What was Grünfeld's playing style?
Grünfeld's style was opening-conscious, Queen's Pawn based and generally practical. He was associated with careful preparation and with hypermodern pressure against the centre. Use the opening-theory wins replay group.
Did Grünfeld only play 1.d4?
He is reputed to have favoured 1.d4 very strongly and is closely linked to Queen's Pawn theory. The replay set reflects that emphasis. Use the Opening theory wins as White group.
What is the Grünfeld Defence idea in simple terms?
Black lets White build a pawn centre, then attacks it with pieces, pressure on d4, and timely pawn breaks. It is a hypermodern answer to 1.d4. Use the Alekhine replay to see the idea in early form.
Is the Grünfeld Defence still playable today?
Yes. The Grünfeld Defence remains an important modern opening at master level and in online practice. This page gives the historical origin; use the related Grünfeld Defence guide for practical modern lines.
Is Ernst Grünfeld a good model for club players?
Yes, especially for players who want to connect opening study to middlegame plans. He shows that openings are not memorised moves only; they create pawn targets and plans. Use the lesson finder.
Is Ernst Grünfeld a good model for advanced players?
Advanced players should study him for historical opening evolution and how early theory became practical strategy. The Alekhine and Kostic games are the key starting points. Use the Grünfeld Defence origins group.
What should club players copy from Grünfeld?
Copy his habit of studying openings as structures and plans, not just traps. Understand which pawn centre you are allowing and how you will attack it. Use the diagram captions for the plan behind each position.
What should club players avoid when copying Grünfeld?
Do not play a hypermodern defence just because it is named after him. You must know when the centre is strong and when it can be undermined. Use the related Grünfeld Defence guide after this page.
What is the best one-session Grünfeld study plan?
Use three games: Alekhine 1922 for the namesake defence, Kostic 1922 for long-term pressure, and Bogoljubov 1922 for a miniature finish. Use the three diagram buttons in order.
What is the best weekly Grünfeld study plan?
Use four sessions: origins of the defence, Merano 1924 White wins, Black-side counterplay and Queen's Pawn miniature attacks. Use the Replay Lab optgroups to separate those themes.
What does the Merano 1924 group show?
The Merano games show Grünfeld's tournament strength and range: Queen's Pawn systems, counterplay as Black and tactical finishes. Use the Merano 1924 tournament run group.
What does the Tartakower game teach?
The Tartakower game shows Grünfeld using active piece play and tactical pressure to reach mate. It is a useful reminder that opening theorists still need sharp calculation. Use the opening-theory wins group.
What does the Spielmann game teach?
The Spielmann games show Grünfeld facing a dangerous attacking player and answering with counterplay. They are useful for Black-side practical defence. Use the Black-side counterplay models group.
What does the Colle game teach?
Colle vs Grünfeld shows Black converting long-term queenside and rook activity. It is a good example of not rushing after the opening. Use the Black-side counterplay group.
What does the Kmoch game teach?
Grünfeld vs Kmoch shows direct attacking play from a Queen's Gambit style position. White's rook lift and queen pressure create a forcing finish. Use the opening-theory wins group.
How does Grünfeld connect to hypermodern chess?
The Grünfeld Defence is one of the classic hypermodern openings because Black attacks the centre from a distance. It fits the broader shift from occupying the centre to pressuring it. Use the Alekhine diagram.
How does Grünfeld compare with Nimzowitsch?
Nimzowitsch is the broader hypermodern strategist; Grünfeld is the opening-theory pioneer attached to a specific defence against 1.d4. Use the related opening card to move from player history to opening practice.
How does Grünfeld compare with Rubinstein?
Grünfeld reportedly admired Rubinstein's style, but his own lasting impact is more opening-theoretical. Rubinstein is a technical model; Grünfeld is a Queen's Pawn and hypermodern-theory bridge. Use the quick facts section.
Should this page link to the Grünfeld Defence guide?
Yes. The page should clearly send readers to the modern Grünfeld Defence guide because that is the most natural ChessWorld next step. Use the related guide card near the bottom.
What opening pages should I read after this?
Start with the Grünfeld Defence guide, then compare related Queen's Pawn and Indian Defence structures. This page gives the historical origin; the opening guide gives practical repertoire decisions. Use the related guide cards.
What is the main SEO value of an Ernst Grünfeld page?
