I don't believe the alternates (Qxa3/Rxd6) are as good as Rxc8 Rcx8 Ncx8 Rd7 Rb3 Qc1 is +4.3 after 14 plies, and black's defense fails low at ply 15 I'd like to see your mainline after Qxa3, as +3 looks rather optimistic. Uri's Rxd6 line is also only +2. >Id: ECM.1100 >Fen: 3R4/1p2kp2/p1b1nN2/6p1/8/6BP/2r1qPPK/Q7 w - - 0 1 >Rb8 looks about the same as Rd7+, both over +3.

The difference is still big and consistent with what I get in other programs.
