pv is preferred variation.  That means that it is the sequence of moves the
computer imagines is going to happen if both parties do their best.

Killer moves are moves that look like really good ideas at first glance.  In
evaluating what move to make, you want to look at pawn x queen and stuff like
that before some quiet sort of move.  That way, if you run out of time, you will
more likely have finished looking at the good moves.

A pv is more or less the computer's current thinking about what the future
sequence of moves is going to be.

A killer move is something that goes into move ordering as far as which
possibilities we should check out first and foremost.
