| 2016-10-29 03:36:02 | MoreKnock | Invalid | This isn't the sort of problem that has only 1 right answer... Why not C15, C14, or D14? For that matter why not C11 or D11? |
| 2016-11-08 16:41:08 | macao | Invalid | too many right answers |
| 2016-11-08 17:43:38 | Doton | Invalid | There is only one move in the problem and there is no explanation at all. |

| 2019-07-09 17:33:13 | iopq | Invalid | let's not pretend only one move is correct, lol |
| 2019-08-19 04:20:06 | Starline | Invalid | more good moves, alphago disagrees with answer, no good explanation for why, just bad problem |
| 2020-01-12 09:51:51 | twop | Needs Fixing | слишком много вариантов |
| 2020-03-29 03:37:51 | Cane | Invalid | This problem has one solution but many correct answers. |
| 2020-12-13 03:26:44 | evanbd83 | Needs Fixing | Needs more variations and more of them marked as correct. |
