Can you win this endgame with only 1.7 seconds left to play?
There are two key things to remember when playing in a clearly won endgame, when you are low on time:
1. Always trade pieces, sometimes even to the extent of losing material, if you end up in a better position. This will make your life much easier beacuse it limits the number of moves your opponent can make.
2. Use premoves
When playing with only seconds left (in this example 1.7 seconds) premoves are necessary to prevent losing on time. Use smart premoves to simplify the endgame. Using premoves, in essence, means playing the game one move ahead of time.
