its about planning
A plan to break open some of his defense, turned out to trap his queen. And soon a little bit, later after my first check a simple plan got me his rook too. And then it became the game of white again.
The game a 5 minute game was a race against time, the whole time.
We didn't play slow, and in the end i had not enough time left to checkmate.
Although i ended with great material win, and I won on time, we where playing in our last seconds.
