I love underpromotions 🙂
Nice, just have to use the right sequence!

3.d4+ Nxd4
4.cd#
or if
3…. cxd (ep)

Nice mate, congratulations for the boy.
i think, it’s not too difficult:
1. Ra1+ Kb6
2. c8N+ Kc5
3. d4+ cxd3 e.p.
4. b4#
3. … Nxd4
4. cxd4#
greets and happy new year, jan
Two nice ideas I see in this problem: 1. minor promotion and 2. en-passant taking. However, the first move is not a ‘silent’ move, and so this is not a very sophisticated problem yet, but… it’s a good one and … may I ask, what’s Tommy’s age?
Solution:
1. Ra1+, Kb6 (only move)
2. c8N+, Kc5 (only move)
3. d4+, cxd3
4. b4 checkmate

1. Ra1+ Kb6
2. c8(N)+ Kc5
3. d4+
If 3. … Nxd4, 4. cxd4#
If 3. … Cxd3 e.p., 4. b4#
1 Ral+ Kb6
2 c8=N+ Kc5
3 d4+ cxd3 ep
4 b4#
Excellent puzzle. I especially like how a dual was avoided on move 3.
Looks like the young puzzlemaker has a unique solution puzzle, as best as I can tell.
1. Ra1 Kb6
2. c8(N)Kc5
3. d4 cd3 (Nd4 4.cd4#)
4. b4#
At move 3, white mates in 5 total by playing b4 first:
3. b4 cb3
4. d4 Nd4
5. cd4#
Tom,
Me, too.
Forced sequence Ra1+, c8=N+, d4+ and depending on black, b4# or cxd4#.
The answer to this puzzle is
1 Ra1+ Kb6
2 c8=N+ Kc5
3 d4+ cxd3( Nxd3) leads to mate because cxd3
4 b4#
ta1+,kb6,c8=N+,kc5,d4,cxd-ap,b4++
Ra1+ Kb6
c8=N+ Kc5
d4+
if …Nxd4, cxd4++
if …cxd4, b4++
Since nobody else supplied the solution (up to the time I’m posting this):
1 Ra1+ Kb6
2 c8=N+!
The only way to force mate in the required number of moves.
3 d4+ cxd3
Or 3 … Nxd4, 4 cxd4#
Black takes the pawn en-passant, but now it’s not available to do the same to the b-pawn.
4 b4#
Good puzzle. But if Timmy decided to become a chess composer, he whould remember that checkmate problems should not begin with a check.
Timmy is Bob Cratchet’s son (Tiny Tim).
Tommy is Susan’s son.
BTW, a chess puzzle can have any form or configuration that is why it is a puzzle, not a game analysis.
He’s 10 I think.
Okie…
Challenge, Tommy: we are waiting for the Valladao theme:
1) Castling
2) En passant and
3) Underpromotion
in the same line…
he turns 12 in march
