I believe these ones can be safely dropped from ECM. They have one of the following wrong with them: 1. Two equally good key moves that make for a problem that is much too easy 2. An outright cook in the key move that is found quickly 3. A faulty defense (book error) that make other key moves just as valid 4. The key move leads to nothing really decisive making it not fit the traditional understanding of what a combination is (also because of a error in the book). 14 16 17 19 28 29 31 43 51 54 63 68 70 71 76 81 84 91 96 99 109 119 131 137 144 145 148 153 180 186 190 193 198 208 215 227 228 231 259 270 274 292 293 298 300 310 312 313 315 321 330 338 345 349 356 366 377 381 390 396 397 411 420 425 434 440 447 462 464 467 474 489 494 497 501 504 505 510 525 539 557 559 560 561 562 592 593 624 627 634 653 677 683 686 691 693 701 702 730 735 754 755 758 767 811 827 836 846 858 860 864 866 865 867 868 875 879 I'll leave this post up for feedback before I assemble together a new draft. Any questions on these deletions? The new draft will also contain changes made to key moves as well as a fix to the epd positions that were in error in the original.
