Go vs Chess

Chess has more rules and fewer moves. Go has fewer rules and more moves. That single trade explains almost every other difference between them.

Rules: Go is far simpler

Chess needs six piece movements plus castling, en passant, promotion, stalemate and the fifty-move rule. Go needs: place a stone on an intersection, capture groups with no liberties, do not repeat the previous position, do not commit suicide, count territory at the end. That is it — see the rules in ten minutes.

Complexity: Go is far bigger

ChessGo (19×19)
Moves available per turn~35~250
Typical game length~40 moves each~150 moves each
Legal positions~1044~2.08 × 10170

This is why chess fell to computers in 1997 and Go held out until 2016: you can brute-force chess with enough search, but Go needs positional judgement, which had to wait for deep neural networks.

How they feel different to play

What AI did to each game

Deep Blue beat Kasparov in 1997 with search and hand-written evaluation. AlphaGo beat Lee Sedol in 2016 with neural networks and self-play, and the open-source engine KataGo that followed now plays far beyond professional level and is free.

The practical consequence for you: a top-level Go teacher fits in your pocket. TseGo runs KataGo on the device, and can also play deliberately at 15 kyu when that is what you need.

If you play chess and want to try Go

  1. Start on 9×9, not 19×19 — it is the "blitz" of Go and games take 10 minutes.
  2. Expect the first ten games to feel formless. Territory intuition arrives suddenly, usually around game 20.
  3. Do tsumego from day one — it is the closest thing to chess tactics puzzles, and it works the same way.
  4. Play a rank-matched bot rather than a strong one; being crushed teaches nothing in either game.
