The board and our range is in the picture below. As you can see in the first two pictures, when our range is quads or 0 equity air, our villain calls with his bluffcatcher 50% of the time vs a pot sized flop bet as is expected, as that is the minimum defense frequency (his range consists of KK only).
When we break the toy game by introducing bluffs with equity, the result was unexpected to me. Villain calls more than MDF. Why is this? (second image)
