In some matches wild ass guess is better but in some you just already know like you can be sure 99% which team's gonna win. Like in West Indies vs Bangladesh this round. Bangladesh is not a good test match team except they recently defeated Pakistan in their backyard (that was a fluke and India proved it by beating them inside 2.5 days). Now they are in the backyard of mighty West Indies who are still very formidable, especially in tests at home.
