If you have nice problems post them here!

119 people look at it but no one posts something.....

I think most people, including myself, are having a hard time understanding what we're looking at here; and what kind of "nice problems" we're supposed to be posting.

Can you please clarify and elaborate?

And people might be wondering why is this on ''Chess960 and Other Variants'' forum

OK, I'll bite. The following Chu-Shogi tsume problem was of interest to me because the solution given in the historic 17th-century manuscript from which it comes was wrong, and in fact already spoils the mate in the first move (f12 x f11). I found the correct solution, which was a mate in 16. (There is the additional requirement in these kind of problems that every move must be a check, which makes such a deep mate much less daunting than when you have to consider all silent moves as well.)

The solution I found is:

1. i12-h12, Kg9 {the King has to stay away from the diagonal e12-l5, because white otherwise can involce the Queen on b5 with check, after which it is over very quickly} 2. k9xj10-i11 {double-move of the Lion, hit and run} i10xi11 {captures the checking Lion} 3. h12xi11 Kg8 4. i11xi6 {check with the 'evil eye' move of the Eagle, which can capture Pawn + King together in one move} Kf7 5. f3-d5 {check through the jumping move} Ke8 6. i6-c6 {check through the other evil eye} Kd9 7. d5-f7 {again check with the jump move} Kc10 8. c6xd7-e8 {removes the black piece 'en-passant' so e8 is no longer defeded} Kb11 9. f7-d9 {this piece could have promoted to Queen here, but then black could have interposed something to block the check, and promotion is not mandatory} Kb12 10. f12xd12 d11xd12 11. a9xd12 Ka11 12. d9xf11=Q {once unpromoted in the zone, promotion is only allowed on a capture, but you make one here} d10-d11 {throws itself in the checking path for some pointless delay} 13. Qxd11 Bc11 {idem} 14. d12xc11 Qxc11 15. Qxc11 Ka12 16. e8-c10#.
