I have two questions, firstly, next month I will be playing in a tourament with a time control of 45min (1 1/2 hr game) is this fast or a slow game ? secondly how many types of time control are there ? can u name them, for example in the world chess champion is 40 moves in 2.5 hrs, is this correct ?

there are alot of time controls . for one the time control you are playing is pretty standard, that i know of and its a long game. i have seen game 90 and game 60. i have played in game 30 as well. here is the fun part alot of tournaments let you play add time or delay time. so the tournament i play at that is game 30 you can chose to play 20 min with 5 sec delay "the black player with clock gets to chose". i for one hate this any time under 30 min is rated as blitz or standard. as for 40 moves in 2 1/2 hours most times i think they are FIDE but i might be wrong,  most times they go 40 moves in 2.5 then 20 moves in 60 min then blitz

45 minutes is pretty fast.  It's not blitz, but it's not standard either.  I usually end up pretty rushed in for example 30 minutes for all moves.  Then again, I consider all moves in an hour and 5 to be rushed.  I think a 3 hour session is fairly normal for amateurs, of say 35 moves in 1hr15 and 15 to finish.  I think most FIDE games are played over a 7 hour session of, for example 40moves in 2hrs, 20moves in 1hr, 30mins to finish.  I believe a 5 hour session is the minimum for fide to rate a game. 

Hi KCO

Only just looked at this thread, sorry

Its this an over the board tournament?

If so... in the ACF a "standard" time length is a base time of 1hr per person or more.  Anything less is classified as rapid.
