Bishop Verses Knight EPD test suite

Material imbalance is certainly one of important new ideas in chess programming.

Sometimes a knight is better and sometimes a bishop, though they have approximately the same point value in general.

When should you trade a knight for a bishop (and vice versa)?
What about the aftermath of the trade (e.g. with a pawn recapture, has the altered pawn structure changed the value of the trade)?

There is a new test suite in the "Strategic Test Suite" arsenal, the fifth of the series by Swaminathan. These positions have had the stuffings pounded out of them by powerful chess engines to ensure that the answers provided are reliable. Besides the key move, there is also a list of hints in the ce that shows the relative value of alternate move choices.
