I think too many people look for a long term winning strategy/system in all tables games and sports betting too, and in my opinion this is a huge mistake. A person could simply search through a list of strategies or systems and hit and run playing the short term game. Very easily achieved. Spend less time on a game. Reduce the risk of losing any profits made by staying on trying to hit again. Easy money.
But also set a stop loss, so that you don't blow all the betting finds as nobody wins all the time, quite often perhaps but definitely not all the time.
