Opposite-Coloured Bishops: IM Baumegger's Strategic Guide
Few features of a chess position are as misunderstood as the opposite-coloured bishops. Say the words to most club players and one thought comes to mind: a draw. And in a pure bishop ending, they are usually right — the defender's bishop guards a colour complex the attacker can never touch, and even an extra pawn or two often melts into half a point.
Yet the very same imbalance, carried into the middlegame, becomes one of the most dangerous attacking weapons in all of chess. The bishop that draws in the endgame is the bishop that kills in the middlegame.
Today, we are pleased to present Opposite-Coloured Bishops by IM Siegfried Baumegger — a complete practical guide to the position type that rewards the side who understands it and punishes the side who assumes it is always drawish.
A Question of Phase, Not Reputation
The mistake many players make is to treat opposite-coloured bishops as a single verdict — "drawish" — and to stop thinking there. The truth depends entirely on the phase of the game:
- In the endgame, the opposite bishops raise the defender's drawing chances. The attacker's bishop can only ever influence one colour, and the extra pawns advance on squares the defender simply ignores.
- In the middlegame, the logic reverses. With the heavier pieces still on the board, the bishop that rules one colour complex becomes an attacker with no opposite number to challenge it — an attack down the wrong-coloured diagonals meets no defensive bishop at all.
The real skill lies in recognising which phase and which side the imbalance favours — and then steering the game to make it count. This course trains exactly that judgement, from the sharpest middlegame attacks to the most delicate endgame defences.
What This Course Covers
The course is built around a clear, four-stage structure, moving from the middlegame — where the attacker holds the advantage — to the endgame, where the balance shifts back toward the defender.
Stage 1 — The Middlegame: Direct Attacks and Tactics. We begin where opposite bishops are most lethal. With the position open and the enemy king exposed on the "wrong" colour, the bishop joins the attack as an extra attacker that cannot be traded off. This stage trains the direct assault: activating the bishop, sacrificing material for the initiative, and driving the attack home.
Stage 2 — The Middlegame: Strategic Play. Not every advantage is a mating attack. This stage covers the quieter side — using the bishop to increase an existing advantage, transforming the pawn structure in your favour, and preparing the attack rather than launching it at once.
Stage 3 — The Endgame: Converting an Extra Pawn. Here the difficulty inverts. With the queens and rooks gone, the defender's drawing resources appear, and the attacker must know the genuine winning methods: creating a second front, using the pawns and king together, and forcing the defending bishop into impossible choices.
Stage 4 — The Endgame: Defending. The other side of the coin, and the most practical stage of all. Knowing how to hold the opposite-bishop ending — where to place the bishop, which colour complex to control, how to build the fortress — turns countless lost-looking positions into half points.
Three guiding principles run through the whole course, stated by Baumegger from the outset:
- Act as energetically as possible — strive for the initiative at all costs.
- The initiative matters more than material.
- Always activate your bishop and bring it into the fight.
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 stage 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 across the whole sweep of the game:
- The classical handling of Rubinstein and Lasker
- The endgame artistry of Smyslov, Petrosian, Karpov and Fischer
- The dynamic attacking play of Tal, Bronstein and Spassky
- Modern battles featuring Carlsen, Ding Liren, Svidler and Aronian
— alongside Baumegger's own games, annotated from the inside. This range shows how the opposite-bishop position has been attacked, defended, won and held 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
Opposite-Coloured Bishops is designed for ambitious players who want to master one of the most double-edged imbalances in chess — the position that draws in careless hands and wins in prepared ones. Whether you are hunting a king down an open diagonal or defending an ending a pawn down, this course delivers the analytical depth and practical guidance that Modern Chess is known for.
Ready to learn when the opposite bishops draw, when they win, and how to make sure they do what you need — one position at a time? This is the guide that settles it.
