When it comes to gamble in sports betting the first thing I evaluate is how much knowledge and skill I have about the sport I am betting on.
Definitely knowledge and skill goes along way in gambling,
There is no how you predict a game without having a knowledge of what you are doing. The knowledge plays the role of skill but people often get confused of skill in gambling. When they talk about skill in gambling, they specifically talks about how knowledgeable you are to predict possible outcome and it plays accordingly, even it is not %100.
I should bet after considering whether I am fit to bet on that game or not. But there are many gamblers who think that betting more will increase their winnings which is a completely wrong assumption.
Although in this aspect of betting more to increase the chances of win is a normal thing. For a person to win you must play many times as possible, you will lose more before win. If a person doesn't play more how would the person increase his chances of winning?
