If you've never played "real" standard chess, maybe you should get some practice before the tournament by joining one of the slow chess groups here on chess.com. This is pretty popular, but there are others:

I woukld like to tke part in the Laval open in the 23 of June. Although I am not too sure on how I will perform at the event even though I have a current rating of 1700 in live standard. Each person will have 1h:30min on the clock with a 30 second increment, do I relly need that much time? Will it impact my performance compared to live standard? Also I wold like to add that I am currently unrated in over the board chess and I will be taking part in section C if I do participate. Will someone please help me with this.
