MLavanur won this arena tournament with 8 straight wins. In most of them the time at game end was similar to this one 9:26 – 10:08 of a G/10 time control. The games are mostly pretty bad because the opponents could not think that fast. When you are playing a speed player, you have to slow down and wait for the mistakes.
