This is what happens, connection-wise:
1. A makes a move
2. move is sent to chess.com
3. move is sent to B
4. B makes a move
5. move is sent to chess.com
6. move is sent to A
7. A makes a move
Et cetera.
Say you're A. During the steps 2, 3, 4, 5 and 6, it looks to you as if it's B's turn (since you made your move, and you haven't seen his yet). However, to B it only looks as if it's his turn during step 4 (it was yours during 1, 2 and 3). And in fact te only time that is actually deducted from his clock is the time he takes for step 4.
So if either of you has a somewhat slow connection to chess.com, both of you are going to think that the other is taking longer than what his clock actually changes.
When I play blitz matches with 2 minutes and 0 seconds bonus, some weird things are happening. Once I make my move, their clock takes sometimes atleast 5 seconds to start, but once they make their move, my clock starts to tick down instantly. This is really bugging me, and has caused me to lose alot of games on time, eventhough I play faster then my opponent. Im not sure if this is because they have a premium account, or if its just my internet connection that is "too" fast compared to theirs, and that this might be the problem.
If anyone know why this is happening or have a way to fix it, this would be great
Thanx in advance
