Like you, I prefer this strategy because I enjoy following the matches I bet on. Perhaps this is the healthiest thing about gambling, meaning that gambling games remain linked only to sports matches. All other forms lead to disastrous results in cases of addiction. Gambling companies are not subject to any restrictions in game designs. Personally, I consider slot games and all online games to be a real waste of time, and I am surprised by this great demand for them.
It has pros and cons.
When you bet on a match you are watching/ following, you are likely enjoying the match and every situation in the match. In entertainment aspect, it is good for you to have fun and refresh your mind.
But it is not only good, if you are a type of person who can be affected by emotion, you will make more extra bet during the match. By emotionally bet more, you are taking more risk with more emotional bets. It will potentially lead you to more inaccurate bet decisions.
For me, Sportsbetting is the best skill+luck based gambling game. In order to have complete enjoyment, it is better for choices and decisions not to be governed by emotion, and for this reason it is always recommended not to bet on favorite teams or players because this can lead to many fallacies. Sports betting may share an intelligence-skill quality with card games like poker or blackjack, but the excitement aspect is much greater with sports games.
In the extreme case, playing sports bets governed by emotion is much better than online games that can be controlled by gaming service providers regardless of the expectations and positions of the gamblers themselves.
I would like to emphasize that the House is not responsible for the choices, no matter how illogical they may seem. It merely displays all the games, leaving room for the gambler to choose.
