fh is the % of nodes searched that were fail-high nodes.  I'm not exactly how
they are computed.

pawns is extensions done for passed pawns (reaching 7th, and some 6th ranks, I
think)

thrt is the amount of mate threat extensions done.  It happens when null-move
detects a mate threat, and possibly at other times (I'm not sure)

Hope this helps.
