There is already a tweet saying that Han has a 200 rating difference between playing in tournaments that relay moves live to the internet and tournaments that doesn’t: https://twitter.com/atl_kings/status/1568656197812891653?s=21&t=kPdURZ0oIf-8T45VkTyDQg https://twitter.com/atl_kings/status/1568656197812891653?s=2... (Live game uses a special board that electronically records the move instantly and broadcast it)
- yesenadam 4y agoA tweet apparently debunking that tweet https://twitter.com/thestrongchess/status/1568810062399021062 https://twitter.com/thestrongchess/status/156881006239902106...

- hutrdvnj 4y agoIf we assume that the data is reliable (not hand picked just to make a case). Then let's check. Two sided un paired t-test. T-value of 4.9. SE of 56.325 Group 1 mean of 2383 with sd 125.56. Group 2 mean of 2659 with sd 119.16 39.7 SEM. P value of 0.0001. By conventional criteria there's about 0.01% chance the differences in the means is due to chance alone. That's 0.0001. I.e. If you were to play 19 tournaments randomly 10,000 times, only 1 in 10,000 would you perform better on live boards as well as Hans did due to chance alone.
