1.Ng4-h6+ Kg8-f6 2.Qc3-h8#

1.Rd7-d8 (double +)
(A) 1…Kc8xRd8 2.Qh3-d7#
(B) 1…Kc8-b7 2.Qh3-c8#

1.g2-g4+ Kf5-f4 2.Rd6xf6#

1.Qh5xg7+
(A) 1…Kg8xQf7 2.Nf5-h6#
(B) 1…Kg8-h8 2.Qf7xg7#

1.…Qa5xc3+ 2.b2xQc3 Be7-a3#. What I always find cute about this pattern: 1…Qc3+ works even if there is no c3 pawn and therefore no capture.

Simply 1.Rb1-g1 followed by 2.Rg6xh6#

Slower but also works, with its own prettiness: 1.Qc4-g8+ Rf8xQg8 2.Ne7-g6+ h7xNg6 3.Re3-h3#

Thanks for that link!
