I just played a 13x13 game with the time setting: Time Control
Simple: 25 seconds per move.
My opponent would always pause and warn me that my time was running out, but I could see 17s on the clock every time, so I didn’t see a problem. I eventually lost the game on time, because my clock ran out at what was shown to me as 15s. Is this a known issue with this time setting? It seems like my opponent could see my clock correctly, otherwise I doubt he would pause as often to warn me.
