Beginners typically decide each chess move by considering the consequences. Expert players, in contrast, primarily us...

@Minerva,

Happy to help. Let's take a look at (B) and (D).

(B) says, "A beginning chess player should use pattern recognition
techniques when deciding what move to make."

This is tricky, as the writers are attempting to get us to think that
chess beginners should use the same techniques as experts. The problem
with this is that it assumes that the usefulness of the pattern
recognition techniques is transferrable to beginners. This is almost
certainly false, as the expert has played in far more chess matches,
so her pattern recognition techniques are likely to be of greater use
to her than for a beginner. Thus, we can get rid of (B).

(D) says, "In playing chess, an expert player relies crucially on his
or her memory."

The definition of "crucially" is "with decisive or vital importance."
The stimulus tells us that expert players primarily use pattern
recognition techniques. While "crucially" is a strong word, we know
that experts have to use their memory in order to use the pattern
recognition techniques, and we know these experts mainly use these
techniques, so this wording, although strong, is supported by our
stimulus.

Does this make sense? Let us know if you have any more questions!
