I don't really play on corners at all, that is a specific thing that some people do care about and follow, but usually what I gamble is either the winner, or the over/under on the goals scored, that's about it.
There are people who bet on even the amount of yellow cars, that is not something I like to use too much to be fair, they go into the research mode and literally check how many yellow cars the ref gave on his previous games and all to play that, it is really not that common thing and I rather not. Just winner and goals are obvious enough. Specially when we are talking about one-off games like these, it is really hard to make a bet like that because teams usually play differently compared to most of their games, it is do or go home games.
Sometimes if both teams' chances of winning are the same then we will bet on the other side like the corner kick in this match the potential is very good as the two teams fight for life and death so their efforts will be higher here, I just checked the final result Aberdeen 1 - 3 Hacken and total corners kick are 15 it exceeds the target of what the gambling market provides. By the way Hacken only drew in the first leg and today they are win it's a bit strange to see them win when playing away the opposite should have happened.
