Welcome, madoldmanI am looking for a directmate problem (ideally, mate in 2) with the following feature:

all first moves by white (except, of course, the mainline solution) lead to a forced win by Black (or maybe a draw.)

Cheers!

It might be a bit obvious, but

1 Ne4! N~ 2 Nc3#

and if White does anything else, Black mobilises his queen.

If the black queen out of play in that first problem was a bit inelegant, here's a 6-man kindergarten problem

Try 1 a3? a4 2 Kd~ and Black frees his king

1 a4! b5 2 axb5#

In that first problem, White has 11 options; in the second, 6. If you like the idea of White having many options, how about these?

White has 15 options. One wins in 2. 14 lose.

Try 1 Qa~? b1=Q+!

1 Kd~? b1=Q+/Ka2!

1 Qb3! b1=any 2 Qxb1#

White has 19 options. One wins in 2. 3 draw. 15 lose.

Try 1 Rd4+? Nd3! 2 Rxd3"!" (White has already blundered one half-point; this is the only move that doesn't blunder the other) Kc1 {Ke1} 3 Rxc3 Kd1! 4 Rc~ c1=Q/R/N (c1=B? 5 Kd3! wins) 5 Rxc1 Kxc1 draw

1 Rf4?/Rh4? Nd3! 2 Kxd3"!" c1=N+! drawing

1 Rg4? Ne2! and Black wins at move 11

1 Ra1! Ke1 2 Rxc1#
