Go Capturing Problems: How to Train Your Reading

"Reading" (yomi) — playing a sequence out in your head before you put a stone down — is the engine of strong Go. Capturing problems train it directly: you are given a target group of stones and must find the move that captures it by force. Because the answer is proven, you get clean feedback on whether your reading was right.

Liberties decide everything

A group of stones is captured the moment it has no liberties — no empty points next to it. So capturing is really a counting problem: compare the liberties of the target group with your own. The move you want is usually the one that takes away the target's last escape while keeping your own stones safe.

Capturing races (semeai)

When two neighboring groups are each trying to capture the other, it becomes a race to fill liberties. Count both sides. As a rough rule, if both groups have the same number of outside liberties and no shared ones, the side to move wins — so you fill the opponent's liberties while protecting your own. Shared liberties and eyes change the count, which is why reading the exact order matters.

How to read a capturing problem

Don't play hit-and-hope. Picture the sequence to the capture first:

• Count the target group's liberties and your attacking group's.
• Find the move that reduces the target faster than it can reduce you.
• Always check the opponent's best escape or counter-atari.
• Watch your own short-liberty stones — don't get captured first.

Why it builds real strength

Reading is the most transferable skill in Go: the same counting and visualization underlie life-and-death, fights, and the endgame. Capturing problems isolate that skill without needing full life-and-death theory, which makes them ideal for beginners and a sharp warm-up for everyone.

How to practice

Solve a lot of them, starting easy. On TsumeDojo every go problem asks you to capture the marked white stones and is verified by exhaustive search, so a wrong answer really is wrong and a right one really works. Re-solving builds the instinct to count liberties at a glance. (Eye-shape life-and-death — eyes, seki, ko — is on our roadmap.)
