It does not matter how many bets you want to do, that can not influence your winning chance, in some days there might be big number of matches which deserve to bet on, like yesterday, there were very important matches in one day, Man United Vs Arsenal, Dortmund Vs Bayern, Atletico Vs Real Madrid, I bet on all these matches, and in other days you might not make any bet. sometimes many matches a day give you a chance to compensate your losses if you lost in one match, or you can make a parley.
Finding value in sports betting is the most important thing you must do to be successful, by aiming money you should stick to the method of finding value and though there are a lot of games available to play online, that does not mean that you have to play them all.
For example, there's a game that both team in your thinking has a 50% chances of winning, would you still go with it? I guess not good because you are then relying to your luck, there's no value then.
But you should consider that there are many types of betting, I do not bet only on a team to win or on a draw, you can bet on both teams to score, or match goals number, match corners, over/under ........
in the example you gave, if both teams have 50% chance, I might choose both teams to score or over/under 2.5 goals, that depend on the match Circumstances and on my analyses for both teams.
I think he is talking about if the team has both 50/50 do you still bet on them.. For me if i am thinking for money or sure win i will not choose both team.. instead i'll go to other game in sports betting since it is not the only game i will find more team that has chance to win than confuse to choose in both team.. So that i am surely that i am using my skill to choose than always relying in my luck.. We know that everything needs luck but you should use your analyse and be smart..
