Trying to dig into teaching games.
There’s no flag about that, so I tried to filter on game name.
I looked for the string “teach” which could possibly appear in various combinations.
I’m keeping only 9x9 and 19x19 boards and considering both handicap and komi.
Here’s a summary:
| Ranked | |||
|---|---|---|---|
| Board | False | True | Total |
| 9x9 | 1980 | 1841 | 3821 |
| 19x19 | 9713 | 2340 | 12053 |
| Total | 11693 | 4181 | 15874 |
About 9k games have actually a title such as “Teaching game” or similar.
Many are like “Please teach me” or “Looking for a teaching game” or “will teach new and high kyu” and so.
Some are… interesting? 
Such as
- destroy the timeout losers! teach them how to resign!
- Not here to teach, not here to learn, noone just another bot
- ultimate teachin
- beginners or teachers pls
- Teaching Lesion for me
- nick sibicky told me i have great talent for making go teachers sad
- looking for a teacher-typeofthing | send me a message in the chat
- three go teachers have given up on me so far
- Teach Me and I’ll Teach You?
and so on 
Let’s see some charts: handicap VS komi.
9x9 ranked games.
Best part are no handicap, standard komi (5.5)
9x9 unranked
Same as before plus a few funny games with 500 komi or 50 handicap
Same chart but removing handicap > 9 and extreme komi:
19x19 ranked
Mainly standard options: no handicap with standard komi or handicap with 0.5 komi.
A single -40 komi game.
19x19 unranked
Some 9 handi with various komi. A few extreme values.
Same chart but removing handicap > 9 and extreme komi.
Standard combinations as seen for ranked games. Looks like reverse komi isn’t very popular on OGS.
Each small dot is 1 to 3 games in this chart.
