Okay what about 2nd half overs, 45-60th min ? Downside is that for a win we need 1 or more goal for a win. It can be tricky, as the 1st half could be very active, last 15 min momentum shows high intensity, but if one is impatient and do not wait for the next 15 min period 45-60, you can also burn as the 2nd half turn out to be different than the first.
However, from my experience if you have a good feeling and a read on a certain competition and the intensity piles up, then there are some good spots for betting and we can not wait for a 0,5- refund line. I have taken a lines where you need 2 or more goals to win, but definitely these spots are tricky. If intensity is high enough, then obviously 20 minutes to 2nd half is a long period enough where you can already secure the bet without waiting to 70-75th minute.
