Here is Crafty's thinking on the matter...
The original position:
[D]r1bq1rk1/ppn1ppbp/2p3p1/4P3/3P4/1QN2N2/PP3PPP/R1B2RK1 b - - acd 13; acn
121730605; acs 1000; ce 35; pv Qd7 h3 Rd8 Bg5 h6 Bh4 Re8 Qc4 Qe6 Qd3 Bd7 Rac1;
Note that since side to play is now reversed, a negative score is good for black
(which was the original side to move)...
After Bg4 {Crafty's least favorite of the bunch}:
[D]r2q1rk1/ppn1ppbp/2p3p1/4P3/3P2b1/1QN2N2/PP3PPP/R1B2RK1 w - - acd 14; acn
133018260; acs 1001; ce 5; pv Qxb7 Bxf3 gxf3 Ne6 d5 Rb8 Qxa7 cxd5 f4 d4 Rd1 Ra8
Qb7 d3;
After b6 {Crafty's second favorite -- only .08 pawns behind the original
choice}:
[D]r1bq1rk1/p1n1ppbp/1pp3p1/4P3/3P4/1QN2N2/PP3PPP/R1B2RK1 w - - acd 12; acn
119806627; acs 1000; ce -34; pv Be3 Be6 Qc2 Nd5 Qd2 Nxc3 Qxc3 Bd5 Rac1 Rc8 Rfe1
e6 Bg5;
After Qd7 {still the favorite}:
[D]r1b2rk1/ppnqppbp/2p3p1/4P3/3P4/1QN2N2/PP3PPP/R1B2RK1 w - - acd 12; acn
116385354; acs 1001; ce -42; pv Bg5 h6 Be3 Rd8 Qd1 Qe8 Qd2 Qf8 Ne4 Bf5 Nc5 Rab8;
After Nd5 {very close to b6, and only .12 pawn behind Qd7}:
[D]r1bq1rk1/pp2ppbp/2p3p1/3nP3/3P4/1QN2N2/PP3PPP/R1B2RK1 w - - acd 14; acn
135875436; acs 1001; ce -30; pv Nxd5 Qxd5 Qxd5 cxd5 Bd2 Bd7 Bb4 Rfe8 Rfc1 Bc6
Rc2 e6 Rac1 Rac8 h3 h6;
According to this analysis, about a tenth of a pawn separates all but the first.
Alright, since I made a silly typo, let's turn it into a bit of fun for you
retro buffs. There is a black pawn missing. Could this position really have
happened?
rb1q1rk1/pp2ppbp/2p3p1/3nP3/3P4/1QN2N2/PP3PPP/R1B2RK1 w - - acd 14; acn
110410305; acs 1001; ce 101; pv Qxb7 Qc8 Qb3 Qd7 Nxd5 cxd5 Bf4 Bc7 Qe3 Rab8 Rab1
Rfc8 Bh6 Bh8;
