Came to a revelation about my approach to WwF games.....
Against MOST opponents, I am in the role of predator. I look for tile placement mistakes and pounce on the opportunity to score big points. I take a lot of risks against them and most of the time they pay off.
There are three players that I have the most trouble with because they are also predators, and if I take a risk, they are more likely to take advantage of it and pile on the points.
I noticed this based on the two games I have going now. In one, I'm the predator. In the other, I'm constantly looking over my shoulder and trying to predict what they might do if I leave this square open.
For the record, I'm ahead in both games, but one is getting a little tense.
