TL;DR SmartGo One now includes a powerful Guess Moves feature for pro games. You can also combine guessing with pattern matching to train yourself on joseki variations.
Pick a pro game, turn on Guess Moves, then at each turn think about where you would play. As you then play each move, SmartGo will tell you whether the move was:
(a) exactly where the pro played, or
(b) at least in the right area, or
(c) at the right spot, but your timing is off, or
(d) whether you’re in the wrong area entirely.
This is a great way to study pro games and learn about your blind spots. This SmartGo Kifu feature didn’t make it into version 1.0 of SmartGo One, but now it’s back, significantly better.
If you’re lost, tap on Hint, and it will reduce the remaining possible area by about 50%. Still lost? Tap Hint again to narrow the search further.
New in SmartGo One is the ability to guess moves of only one player – just choose whether you’re guessing both colors, only black, or only white. Another new feature is the ability to change the size of the area considered ‘near’. It defaults to a Manhattan distance of 5, but you can now set that anywhere from 2 (more difficult) to 7 (easier).
New in SmartGo One, you can combine guessing with joseki or fuseki matching. In this case, SmartGo will just give you a right or wrong answer – getting close in joseki is not good enough. Of course, this feature also works for guessing both colors or just one.
When guessing a joseki move, one of your choices is to tenuki (play elsewhere), and SmartGo will let you know whether that is indeed a position where it’s okay to tenuki.
At any point, you can turn on Hint to see the full joseki information for the current position. Note that obscure variations that have rarely been played are counted as wrong.
Restrict games for matching
You can now choose to use only recent games for pattern matching, instead of always matching in all games. Joseki change over time, and some drastic changes have happened in the last years since AlphaGo. (See e.g. the just released ‘Joseki Revolution’ book by Shibano Toramaru.) For example, comparing the attach-and-pull-back joseki in games since 2016 with games since 2020, the solid connection has gone from 48% to 91%, and tenuki from 18% to 2%.
When you train joseki, it uses the subset of games you’ve specified in Settings > Games > Games to Match.
SmartGo Kifu kept track of your percentage of exact and near guesses. As yet, SmartGo One doesn’t keep track of any statistics, as the feature is mainly designed to help you learn. But trying to beat your previous percentage might add some motivation, so I will likely add this in a future version. Please let me know what statistics you would find helpful.
Enjoy! Let me know how you use this feature, and if there are any tweaks that would make it more useful to you.
