Crafty 16.4 never even looks at Bxc3, as far as I can see. Here is the result
run at my normal time controls:
r1b1k1nr/pp2ppbp/2p3p1/2p5/1q2P3/2NP1N1P/PPP2PP1/R1BQ1RK1 b kq - acd 14; acn
86151418; acs 771; ce -62; pv Bd7 a3 Qa5 Bf4 O-O-O Ne5 Be6 b4 cxb4 axb4 Qb6 Qd2
Qd4 Ra5;
Here is the log of the analysis, showing that crafty never even considers the
bad choice mentioned, even from the first printouts at 1/3 of a second. On the
other hand, crafty is not too thrilled with the eval, at -.62 pawn. My burning
question is, is Nf6 definitely better than Bd7?
