I mostly focus on football matches to increase my capital… I am not necessarily concerned with the odds of the bets, but rather with the “certainty” that the bet event will occur. I usually proceed as follows:
Strategy 1:

At bwin and other providers are in the field of football in the live betting the bet “How many goals are scored between minute 15 and 30 ?”. (always in quarter-hourly intervals) There is here at bwin the option more/less than 0.5 and 1.5 to bet. I select the variant 1.5.

I wait until 5-6 minutes have passed in this quarter hour without a goal, because as long as the live bet at bwin usually remains open, then bet on the result less than 1.5 goals.

The probability that in the last 10 minutes or so still 2 goals fall is almost unlikely, but the odds of about 1.03 with the appropriate stake and low risk quite acceptable. With this, you can quickly earn a few euros on the fast.
Strategy 2:

The half-time bet: If a team is leading 5 minutes before half-time, it is highly likely that it will take this lead into half-time; the situation is different at the end of the game, when the trailing team tries everything again; so bet on the half-time lead!

The odds are generally rather low, but safe!
