The problem over time

Hello ... In an absolutely winning position, I was defeated by time, although the opponent had expired on my timer ... It was very disappointing ... I ask to figure out the situation ... I was online and burned green

Play with increment if you don't want this to happen.

Increment? What is it like? I had 4 minutes of time

Increment is when for every move you make, you get a certain amount of time. This makes it harder for you to run out of time. For example - 3+2 Blitz.
