Very neat miniature. A study in geometry ! It seems that the two pawns can be removed in this setting:

WKd1, WQc1 BKd8, BRc2 BLI a5 H#3 2 Solns.
1.Rc8 Qc3 2.LIe1 Qe5 3.LIe8 Qd6#
1.Rc7 Qc5 2.LId5 Qd6+ 3.LId7+ Qf8#

Mixed color bristol is a bonus, but the solns. are slightly uneven with cross check in only one of the solns.

Julia ,Seetha,
Thank you for the mixed Bristol. The cross-check can be eliminated shifting WK say to h1.
The prob. is ok even with NOWK

You are right Ganapathy. I saw that the WK is not needed. I liked the cross check effect, that is why had WKd1!

Ganapathy, in your original version, the white queen was free with lot of choices. But reducing two units is a worthwhile price, I believe. Thanks for publishing it jointly.

Here is an example using set play.

h#3*
white Qg3
black Kd8 Rc8 LIf6

1…Qg3-g7 2.LIf6-h8 Qg7-f8+ 3.LIh8-e8 Qf8-d6#
1.Rc8-c7 Qg3-e5 2.LIf6-d4 Qe5-d6+ 3.LId4-d7 Qd6-f8#

Matching checks, with mate by Qf8-d6 in set play and Qd6-f8 in real play! The white queen could start on g5.

Thanks Geoff. The set play idea is very neat and the interchange of W-moves is probably valuable. But the play has become more symmetric.
