The latest installment in this best seller: No. 681 (Rxh7): This is a bad one: Rxh7 Qxd1+. Worse, the simple Qh2 wins easily (h5 Be2). Recommend: Changed key to Qh2. No. 683 (Rxh2): I don't know about this. The continuation I analyze is 1... Rxh2 2.Kxh2 Qh8+ 3.Kg1 Nxg4 4.Rf7 Qh2+ 5.Kf1 Qh1+ 6.Ke2 Qxg2+ (not Qxc1 7.Rf1) 7.Kd3 Nf2+ 8.Rxf2 is unclear. Recommend: Drop it. No. 684 (Nxh7): I don't find a continuation for this knight sacrifice. Recommend: Investigate. No. 686 (Bxh7+): Maybe it works but I cannot find better than a draw after 1.Bxh7+ Kxh7 2.Qh5+ Kxg7 3.Rd1 Recommend: Investigate. No. 687 (Bxh7+): I think it's bad: 1.Bxh7+ Kxh7 2.Nxf7 Kg6 is better than it seems, though 3.h4 Qc6 4.h5+ Kh7 5.g6+ Kg8 6.h6 is scary. Recommend: Drop it. No. 693 (Bxh7+): 1.Bxh7+ Nxh7 2.g6 Nf8 black seems fine. Recommend: Investigate. No. 698 (Bxh2+): It's probably bad 1...Bxh2+ 2.Kh1! and black is in trouble. Recommend: Drop it. No. 699 (Bxh2+): I think I see a problem here: 1...Bxh2+ 2.Kxh2 Qh4+ 3.Kg1 Bxg2 4.Kxg2 Rc6 5.Bf4! and white holds. Recommend: Drop it. No. 702 (Rxg7+): Rxg7+ is right, but Rxf7 is just as good (Kxf7 Rf5+). Recommend: Add Rxf7. No. 706 (Rxg7): There seems to be something wrong with Rxg7, but fxe6 is clearly winning: fxe6 Bxe6 Rxf6 game over. Recommend: Change key to fxe6. No. 712 (Nxg2): This is bad: 1...Nxg2 2.Nxb7. A nice refuation on the opposite side of the board. Recommend: Drop it. No. 718 (Rxg7+): How is this supposed to work ? I see: 1.Rxg7+ Bxg7 2.Rg1 Rc8 3.Bxe4 Kf8 4.Rxg7 b3! how does white improve on this ? Recommend: Investigate. No. 719 (Nxg2): I can't see anything decisive out of the key. Qe6 looks like the best move (+108). The threat of Qg4 wins a pawn at least. Recommend: Change key to Qe6. No. 722 (Rg3): 1.Rg3 Bd7 2.Rxg7+ Kxg7 and what comes next ? Recommend: Investigate. No. 725 (Rxg2+): Black can choose between two winning moves: Bh3 and Qf3, both look better than the key. Recommend: Drop it. No. 730 (Nxf7): I get Nxd7 (Nxd7 Bd6 +114). Nxf7 doesn't look less convincing. Recommend: Drop it. No. 754 (Bxf7+): I can't find a winning line: 1.Bxf7+ Kxf7 2.Qb3+ Ke8 3.Nd5 Bd6 Recommend: Investigate. No. 758 (Bxf6): I am guessing that the intent is 1.Bxf6 gxf6 2.Nxf7 Kxf7 3.Qh7+ but I don't see that this leads to a win. Recommend: Investigate. No. 762 (Nxf7): I don't know how this is supposed to work. E.g. 1.Nxf7 Kxf7 2.Qe6+ Kf8 3.Bb3 Nd5. Recommend: Investigate. No. 764 (Nxf7): I have a bad position. White has three knights ? Recommend: Find the right position. No. 766 (Nxf2): The best moves looks to be Bxh3 (Bxh3 Qh4). Recommend: Change key to Bxh3. No. 767 (Bxf7+): This is unclear. Bxf7+ is the best move, but how does it win ? (1.Bxf7+ Kxf7 2.Rxf5+ Kg7 3.d7 Nxd7 4.Qxd7+ Kh8). Recommend: Investigate. No. 769 (Bxf7): Be7+ is clearly better (Kg8 Bd6). Recommend: Change key to Be7+. No. 799 (Nxg6+): Rxf5+ is better (exf5 Nd7+). Recommend: Change key to Rxf5+. Amir
