Although the way Romania played against Ukraine I will say the match is a worthy risk. I will use a strategy I once read in this forum. That is Play Romania to win and then if they take the lead I will play Belgium to win or draw. Because Romania taking the league means Belgium odds will definitely increase.
There are tons of risks with that kind of insurance bet in such a game at such nuts odds.
You take Romania to win at 7:1, good, Romania scores and you think Belgium at suddenly 2:1 would be your safe bet.
Now, what happens if Belgium scores first? You're done for with that bet and Belgium will go down to 1.2 at most for the win and probably not even 1.05 for a draw, so you're going to have to bet maybe even x20 just to balance the table
You're not only betting at a risky stake first but you're also trying to insure your bet in the game, diminishing the returns with another risky gamble.
Why not simply go for the goal or for first-half handicap?
I would be so sure to conclude that Portugal will destroy Turkey, maybe you are underestimating them. Turkey comfortably defeated Georgia 3-1 whereas Czech Republic couldn't win them and almost lost to them. Remember than Czech Republic always won Portugal if not of the late goals that helped the later win 2-1. Based on this analysis, I think the best result Portugal can get tonight is a draw. If I'm to bet on the match, I will go with both teams score to be on the safer side instead of going for outright win.
Ddi you actually watch the games? Or are you just looking at the results?
