Is true that knowing everything about a particular sport those not grantee you winning always but is an added advantage when you are gambling because it brings you more wins.
If you have a friend who is an expert in the other sport where your knowledge is limited and he gives you a game to play, a game with good odds, there are many who will abandon any principle they have about gambling on only the sport they are familiar with and try out their luck on these games. My point is that it is the best practice and one of the basic principles to increase your chances of success by betting on only sports that you are familiar with, but just like other principles, it is always more difficult to practice.
