It is a big advantage to our part if we have knowledge in a certain game what we would like to bet and this could help us to increase our chances of winning. That is why I only put my bet is basketball games coz I have the knowledge of this and I am watching each team performance. But nothing could bring us to the winning streak if we don't have luck, even though we know such a thing and even we apply our strategies.
We deeply know about the games we love and even we could predict the game play of each of the player depending on his history. I personally love cricket and I can actually predict the bets when my favorite players hit the pitch.
I also have knowledge about the tricks used by most of the players which might include their playing strategies and also most of my favorite players are some of the best finishers so I can easily bet and make myself some profits if they are on the pitch and playing more than 2 overs. This is my personal prediction and each of the individual might have his/her own prediction depending on the game he/she likes. We should avoid playing games which we don't gain interest because we can face loss betting in such sports.
