Here are some more comments on positions 101 thru 150. Once again, cross-checking is needed and welcome. No. 112 (Qc6): This one's correct, and also difficult and subtle. Black is a piece up but what to do about the threat of perpetual Ng5+ ? Qc6 throws a piece and gets it back like this: Qc6 Qxe5 Bb7 Re1 Kh8!! Amazing. Recommend: No change. No. 115 (Nxh7): Correct and difficult. Recommend: No change. No. 117 (Ne7+): The key move is a 1-ply combination, but Ra7 is much stronger and neat. Recommend: Change key to Ra7. No. 123 (Nxd6): The key move is not really satisfactory, I think. Stronger is Bxe5. If dxe5 Nh4 and if Rxe5 Nd7 both win a piece. Recommend: Change key to Bxe5. No. 130 (Rxe7): I nearly wrote off this one as incorrect, but it works: Rxe7 Qxe7 Qf3 Kg7 Nce4 dxe4 Nxe4 Qe6 Bxf6+ Kg8 Qf4! wins. Should be quite difficult. Recommend: No change. No. 131 (c5): I get g4 Bg6 c5 etc. It looks like a transposition since after c5 Nxd5 white should play g4 immediately or the next move. Recommend: Add g4 as side solution. No. 133 (Rxe4): Seems correct, though the score is unconvincing. Recommend: No change. More analysis please. No. 137 (c6): c6 doesn't look like it really works. Anyway I get Qe2 which is more convincing. Recommend: Change key to Qe2. No. 142 (d3+): I don't see the point to the key. d3+ Kh1 and then what ? I tried Qa1 and Qf2 but they fail. Recommend: Get rid of it. No. 145 (Bd4+): Bd4+ does something, but is a waste of energy. I find Rf2! an original way to guard the rook which incidentally wins a piece. Recommend: Change key to Rf2. No. 148 (Rfc8): I think it's correct, but I need a stronger machine for this than this notebook. At long analysis I find only Nxf4 for a draw score, but a long analysis of Rfc8 starts showing plus scores. Recommend: Needs more analysis. Amir
