User supplied positions will be added next Friday. To submit position to be included:
| Nick | Position (s) | Puzzle game(s) (if any) | Reason |
|---|---|---|---|
| erdmundr | 8/8/3k4/3p4/3P4/3K4/8/8 w - - 0 1 7k/7p/7P/7K/8/8/8/8 w - - 0 1 | In both settings, the win of the pawn cannot be forced, so I want to get a sense for the type of terminal position that might arise. | |
| BehaardtheBonobo (1st) lmabacus (both) | 8/4K3/6q1/3Q4/6k1/8/8/8 w - - 0 52 1k6/8/8/2K5/2Q5/8/7q/8 w - - 0 11 | g14 51... Qxg7 g17 10... Qxh2 | Why capturing the pawn is not optimal for black. |
| mrbdzz | 8/P1K5/3r4/8/1k6/5P2/8/8 b - - 4 6 | g97 6. Kc7 | why 6. Kc7 was not played (my hypothesis = 0 plies draw) |
| Aloril42 | 7k/8/8/8/8/6q1/8/3Q1R1K b - - 0 1 | Play 3-fold repetition or get mated: how long it is? | |
| lmabacus | 8/8/1n2B1k1/4K3/6P1/8/8/8 w - - 0 68 | g22 67... Kg6 | The final position has the black king with only one drawing move, which echos a lot of the other games, but black could have played 67... Kg6 and been guaranteed at least two drawing moves on the next turn. Maybe white can force a stalemate on that move? |
| ccm__ | 5nb1/8/8/8/8/7k/3r4/3Q1R1K b - - 0 1 5n2/8/8/8/8/7k/3r4/3Q1R1K b - - 0 1 | Also total 3 alternative moves | perpetual or a good draw or a not-so-good draw, which is better? |
| ccm__ | 4k3/4q3/3BK3/3Q4/8/8/8/8 w - - 0 1 | Also other move | stalemate or "good draw"? |
| mrbdzz | 8/8/8/8/3k4/8/1K6/8 w - - 0 1 | g63 start pos white to move | hypothesis: black mirrors white's moves until the king has opposition; just like in the other game |
| mrbdzz | 7k/8/8/8/8/8/8/K7 w - - 0 1 | I'd still expect that opposition will be gained by matching horiz/vert moves with horiz/vert moves, and diag moves with diag moves; and the game ends when there's opposition | |
| lmabacus | 8/8/8/8/8/3k4/8/1K6 b - - 0 1 | g63 except shifted down 1 | I'm expecting black to have the initiative is this game and for the game to end after one move after Kd2 or Kc3 |
| BehaardtheBonobo Aloril42 | 5n2/8/8/8/8/8/3K4/1k1B4 w - - 0 1 8/6n1/8/8/8/3kB3/8/K7 w - - 0 1 | KBvKN longest white win and longest black win | |
| BehaardtheBonobo | 8/8/4K1N1/8/8/6k1/8/5r2 w - - 0 56 | g73 55... Kxg3, also additional move later | So that we can know if Black wins in that case, which would mean some win condition is reached when Rg3+ is played |
| mrbdzz | 8/8/8/3K4/3N4/5Q2/3q4/6k1 w - - 0 99 8/8/8/3K4/3N4/5Q2/3q4/6k1 w - - 0 99 8/8/8/3K4/3N4/6Q1/3q4/6k1 b - - 0 99 8/8/8/3K4/3N4/6Q1/3q4/7k w - - 0 100 | g14 98... Kg1 g14 98... Kg1 g14 98... Kg1 99. Qg3+ | Looking for forced repetitions |
| mrbdzz | 8/6K1/6P1/4Q3/6k1/5q2/8/8 w - - 0 72 | g14 71... Kg4 | Looking for forced repetitions |
| mrbdzz | 8/6q1/8/7R/3k4/8/8/K6R w - - 0 4 | g86 3... Qg7 | Looking for forced repetitions |
| mrbdzz Aloril42 | 5r2/8/8/2R5/8/8/2K2k2/8 b - - 0 2 8/5r2/8/2R5/8/8/2K2k2/8 w - - 0 3 8/5r2/8/8/2R5/8/2K2k2/8 b - - 0 3 5r2/2R5/8/8/8/8/2K2k2/8 b - - 0 2 | g90 2. Rc5 g90 2. Rc5 Rf7 g90 2. Rc5 Rf7 3. Rc4 g90 2. Rc7 | Looking for forced repetitions |
| lmabacus | 8/4N3/8/1r6/8/5k2/1B1K4/8 w - - 0 1 | remove moves before g80 4... Rb5 | To see if moves are affected by previously reached positions. |
| Aloril42 | 8/8/8/2K3k1/8/8/8/8 w - - 0 1 | What about kings with more distance? | |
| Aloril42 | 8/8/8/3K2k1/8/8/8/8 b - - 0 1 | above position with 1. Kd5 | What if a bit less distance? |
