Keep in mind that it's not only the MO market that you can trade with CS...you can trade any other market...it always comes back down to taking a position and trading around that position as the match goes into play.
It's the initial position that is key to all this I feel. Do the homework, study the stats and look at team sheets/team changes etc. Take what you believe is the the most likely outcome for the match and select the market that gives you the best odds to support your opinion....as well as choosing the market that allows you to trade appropriately should the trade go against you...
Sadly, there is no substitute for actually 'doing it'! Just keep the stakes low until you are comfortable with whatever strats you are learning about. Once you become totally familiar with the strats that you've chosen, then you can begin to increase your stakes/profits (but slowly....

).
