1 word is enough, ping

His opponent is getting 1 second, but the displayed timers run locally on the client, so ping plays a role here. His opponent moved at 0.7, but because of the ping between Kramnik and him it takes ~0.2 seconds to be sent to Kramniks client, thus his timer adding 1.2 seconds. Because of this delay, the server communicates a time that is not synced with the local timer, thus the local timer adjusts itself. In this adjustment Kramnik gets 0.1s added onto his local timer (hinting that the ping is somewhere between 0.1s and 0.2s and is getting rounded to the nearest 0.1s on the local timer). He also gets one second, but his timer was about to turn to 3.8 and the time shown after his timer freezes is the corrected server time, not his out of sync local time. You can count the frames; every 0.1s is shown for 12 frames (meaning his phone records at 120fps), 3.9 is shown for 9 frames which means he really had 3.925s (3.9s is shown starting at 3.999s; depending on the server tick-rate it might be more or fewer 9s) on his local timer, the time is then added and corrected by the server. 3.925s is rounded to 3.900s, which is one increment (again depending on tick-rate; likely something like 0.01s or 0.001s) before the timer turns to 3.8 and thus is rounded to 3.8s (3.899). This means he effectively lost a 40th of a second to rounding in this instance, which is not even close to being relevant in reaction time (avg human reaction time is about 10 times that) and negligible (especially when considering that he also gained such small amounts in other instances due to rounding up). Kramnik is (again) making hasty and not at all thought-through judgements about things he does not care to understand. Nothing about this is fishy, this is just how internet technology works.

@@lyxsm Great answer. Kramnik has a lot of issues. That being said, i can understand him airing his frustrations since pings and server times and whatnot is not common knowledge. Especially with people in kramnik's generation

@saz100 Ping is more or less irrelevant; it's the transfer of data packets that determines how fast or slow the connection is. You will have situations all the time were lag exists even with low ping because of this

No, not crazy, just sad that he is no longer a top super GM anymore

His ego can't face reality, and such things end up usually in craziness.

Yes, but Carlsen still wins.
