Attacking Strategies in Positions with Opposite Castles
A practical guide to the sharpest race in chess — by IM Siegfried Baumegger.
When the two kings castle on opposite wings, the game changes character entirely. There is no more manoeuvring for small edges, no slow accumulation of advantages. Both sides throw their pawns forward at the enemy king, and the game becomes a race — whoever arrives first, wins. As Baumegger puts it: king safety is the top priority, and for a successful attack we can sacrifice the entire army.
Today, we are pleased to present Attacking Strategies in Positions with Opposite Castles by IM Siegfried Baumegger — a complete practical guide to attacking, and defending, when the kings sit on different sides of the board.
Why Opposite Castling Is Different
In same-side castling, an attack that fails usually costs only a pawn or two. When the kings are on opposite wings, the stakes are far higher: both sides are attacking at once, and the margin between success and disaster is a single tempo.
That creates a permanent tension the course is built around:
- Attack as fast as possible — every tempo counts, and a half-move's delay can decide the game.
- But never attack prematurely — launching before your army is mobilised, or while your own king is loose, hands the initiative to the opponent, who is racing toward your king too.
The whole art lies in finding the healthy balance between offence and defence — knowing when to push, when to prepare, and when to switch to counterplay.
The Attacking Toolkit
The course is organised around the recurring motifs that decide these positions, each trained through carefully selected exercises. You will learn to:
- Exchange the key defensive pieces — remove the defenders before you strike.
- Use tactical nuances to accelerate the attack and open lines.
- Find the crucial preparatory move — the quiet improvement that makes the assault work.
- Seize the initiative with sacrifices — investing material to arrive first.
- Force weakening moves in the opponent's king position, creating the targets to aim at.
- Recognise the opponent's resources — seeing their counterplay before it arrives.
- Initiate timely counterplay of your own when defence is the more urgent task.
Together, these turn the opposite-castling race from a chaotic slugging match into a structured, understandable fight — one you know how to win from the attacking side and survive from the defending one.
The Baumegger Method
IM Siegfried Baumegger brings decades of practical and teaching experience to this course, with the emphasis that defines his work: pattern recognition and transferable principles, not rote memorisation. The material is delivered as a structured study file of exercises and fully annotated model games — each opening with its strategic guidelines, then a set of test positions to solve, followed by the complete games and solutions.
A Journey Through Chess History
The examples are drawn from the players who mastered the opposite-castling attack best:
- The classical attacking play of Tarrasch and Torre
- The deep understanding of Smyslov, Petrosian and Fischer
- The dynamic sacrifice of Tal and Vaganian
- Modern battles featuring Kramnik, Gelfand, Yusupov, Vitiugov, Naiditsch and Marin
— alongside Baumegger's own games, annotated from the inside. The range shows how the opposite-castling race has been run — and won — at every level of the game.
How the Course Is Organised
The course follows the Guided Practice method: set up each position, decide on your move and your plan, and only then compare your decision with the solution. Active problem-solving is what turns a guideline into a genuine skill — so the exercises come first, and the annotated games reward you with the full reasoning once you have committed to an answer.
For the Serious Competitor
Attacking Strategies in Positions with Opposite Castles is designed for ambitious players who want to master the most exciting — and most dangerous — situation in chess: the mutual attack, where hesitation loses and precision wins. Whether you are storming the enemy king or holding your own under fire, this course delivers the analytical depth and practical guidance that Modern Chess is known for.
