Lasker needed to win this game, and he chose the one opening that would make a contented opponent uncomfortable. The Exchange Ruy Lopez trades queens early and heads for the sort of ending Capablanca loved, but it hides a permanent flaw in Black's structure: four healthy king-side pawns against three, and a queen-side majority so crippled by doubled pawns that it can never make a passer. Take one idea into your games, count majorities by what they can produce, not by how many pawns they contain.
White's four against three can manufacture a passed pawn. Black's four against three on the other wing cannot, because the doubled c-pawns block each other.
Doubled pawns are tolerable when a capture can undouble them. When they are asked to advance and create a passer, they simply get in each other's way.
Lasker picked a line that forces the second player to be active. Against a man happy with a draw that is worth more than an extra half-pawn of evaluation.
Watch the lesson, then play the game through on the board below. The board stays with you as you scroll. Make each move yourself while you read. You'll remember a plan you played with your own hands far longer than one you only watched.
After 4.Bxc6 dxc6 the pawn count is level and the structure is not. White's king-side four against three is healthy and can produce a passed pawn by force. Black's queen-side four against three contains doubled c-pawns, and a majority with doubled pawns cannot generate a passer without help, because the front pawn blocks its own partner. Capablanca knew it and said so in his notes, that with every piece exchanged White would be effectively a pawn up. The rest of the game is Lasker patiently steering toward that truth, keeping enough pieces on to avoid a drawn simplification while manoeuvring toward the moment he can play the break. When it comes, 35.e5, the structural verdict turns into a concrete one. In your games, judge a majority by whether it can actually make a passed pawn, and treat a doubled majority as a majority in name only.
Lasker had to win, and he selected the Exchange Variation because Capablanca in this tournament was content to draw. The line gives Black the bishop pair and the illusion of comfort, then removes the queens and asks a quiet question that never goes away. Reti observed that Lasker used this system precisely against opponents who were happy with half a point. The opening choice was not about the objectively best move, it was about which position his particular opponent would handle worst, and that judgement is itself a chess skill.
After 7.Nxd4 the queens have left the board and each side has four pawns against three on one wing. It looks symmetrical and it is not. One of these majorities can make a passed pawn and the other cannot. Stop and assess before you read on.
Material is level and both sides have a majority. Which majority is real, and why?
Look at the c-file. What happens when Black tries to advance the queen-side pawns to create a passer? Think, then reveal.
Lasker converts the structural edge in three stages. First he restrains, keeping enough material on the board that Capablanca cannot trade into a comfortable draw, and improving his knights while Black's pieces sit passively. Second he advances on the wing where his majority is healthy, f4 and f5 and then g4 and h4, gaining space and squeezing Black's counterplay to nothing. Third he breaks, 35.e5 opens the position at the exact moment when Black's pieces are worst placed, and the passed pawn and the exposed king decide together. By 40.Ra8+ the position is over. In your games, follow the same order, restrain first, advance the healthy majority second, and break only when the opponent has run out of useful moves.
Lasker has spent twenty moves improving his position and restraining Black's counterplay. Every white piece is now on a useful square and Black's are not. It is the moment the structural advantage becomes a concrete one.
White to play. Everything is prepared. Which break turns the healthy majority into a decisive advantage?
35.e5, the break the whole game has been building toward. It opens lines at the precise moment when Black's pieces are least able to answer, and because White's king-side majority is healthy the resulting passed pawn is real. Black's queen-side majority, meanwhile, still cannot produce anything, the doubled c-pawns see to that. This is why Lasker was willing to spend twenty quiet moves restraining and improving, a break is only strong when the opponent cannot meet it. After 36.Ne4 the knights swarm, 38.Nxd7 wins material, and the game ends quickly. In your games, prepare the break until the answer to it is inadequate, then play it.
Once the position opens, White's better-placed pieces decide immediately. The knights come to e4 and c5, Black's pieces are tangled on the back rank, and 38.Nxd7 collects material with the attack still running. The crippled queen-side majority has contributed nothing to the game, which was the point from move four.
Lasker finishes cleanly with 39.Rh7 and 40.Ra8+, and the win gave him the tournament. The instructive point is that nothing tactical decided it, the imbalance was chosen at move four and simply nursed for thirty moves. Carry it into your games, when you assess a pawn structure, ask which majority can actually manufacture a passed pawn, and steer toward the position where yours can and theirs cannot.
The rule: count what a majority produces, not how many pawns it holds. In this game: Black's four against three could never make a passer. In your games: before you trade into an ending, ask which majority is real.
The rule: doubled pawns are acceptable when a capture can undouble them, and a liability when they must advance. In this game: the c-pawns blocked each other for forty moves. In your games: accept doubled pawns only where they will not be asked to create a passer.
The rule: a break is strong only when the opponent cannot answer it. In this game: Lasker spent twenty moves making 35.e5 unanswerable. In your games: improve every piece first, then open the position.
The rule: when your edge is structural, keep enough pieces on to stop a drawing liquidation. In this game: Lasker never let Capablanca trade into a holdable ending. In your games: trade the pieces that defend, keep the ones that press.
The rule: practical chess includes the person across the board. In this game: Lasker picked a line that punishes a drawing mood. In your games: steer toward the structures your opponent is least comfortable in.
Because a majority earns its value by producing a passed pawn, and doubled pawns cannot do it alone. The front c-pawn blocks its own partner, so Black's four against three on the queen-side is a majority in name only, while White's four against three on the king-side is a real one.
When they can undouble themselves by capturing toward the centre, or when they are not needed to create a passer, for instance when they hold important squares or open a file for a rook. They are worst when your plan requires them to advance.
Partly structure and partly psychology. It trades queens early and produces exactly this structural imbalance, and Reti noted Lasker used it against opponents content with a draw, because it forces the second player to play actively or slowly get worse.
It converts the structural verdict into a concrete one. The break opens the position at the moment Black's pieces are least prepared, and because White's majority is healthy the passed pawn that results is genuine. Everything before it was preparation.
Played for activity rather than for the draw. The position after the exchanges is not lost, but it is one where passive play slowly loses, because Black has no way to generate his own threats. When your structure cannot create a passer, you must find piece activity instead.
