Subject: Why do grandmasters love these moves?

Author: Andrey Popov

The following four positions are taken from Dann Corbit's best7.epd file.
In these positions GMs use only one move more than 100 times.
They never use other moves (at least in Dann's games collection).
The grandmasters' opinion seems to be strange.
Which positional reasons can your suggest for GM's choise?
1)
[D]r1bqk2r/1p2bppp/p1n1pn2/8/P1Bp4/4PN2/1P2QPPP/RNBR2K1 w kq - bm exd4; c0
"exd4(105)"; am Nxd4;
Grandmasters love exd4. Why not Nxd4?
2)
[D]r1bqk2r/pp1n1ppp/2pbpn2/6N1/3P4/3B1N2/PPP2PPP/R1BQK2R w KQkq - bm Qe2; c0
"Qe2(196)"; am O-O;
Grandmasters love Qe2. Why not O-O?
3)
[D]rnbq1rk1/ppp2pbp/3p2p1/3Pp2n/2P1P3/2N1BP2/PP1Q2PP/R3KBNR b KQ - bm f5; c0
"f5(180)"; am Nd7;
Grandmasters love f5. Why not Nd7?
4)
[D]rnbq1rk1/ppp2pbp/3p2p1/3Pp2n/2P1P3/2N1BP2/PP4PP/R2QKBNR w KQ - bm Qd2; c0
"Qd2(180)"; am Nge2;
Grandmasters love Qd2. Why not Nge2?
