The first one is cooked. Bc1 and Ba3 work just as well for mate in 3. Haven't solved the second one in more than 4 ways to tell yet ;)

Cool.

doodinthemood is right, I've made a mistake. In the first one the bishop would have been on the a1 square.  Have someone solved the second one?

The second one is 1.Kf3 g8Q 2.Nf2+ Qxf2+ 3. Kxf2#

Correct, black's pawn can transform into Queen, Knight, Bishop or Rook as well. In all solutions, the first move is Kf3.

Ok,

I have a problem with the solution to the second problem.

After 1.Kf3 g1=Q, where does White play without putting his King into check?

He can't move to e3, f2, or g3. And if he moves to another square, Black just interposes with his Queen. White can certainly check with his Knight, but the best White can do is a draw.

Well, after 1.Kf3 g1=Q white should move 2.Nf2 check, and the only defence is Qxf2... But white's king can capture it, so 3. Kxf2#

Ok, thanks!

First problem has an incorrect position:Bb2 must stay at a1!It is a famous problem by
Galitzki.

I think there is only one solution. 1. Ng5 2. Kg1 2. Ke1 h1=any 3. Nf3+ mate

Yes there is (post #8), but it is not yours. Black defends with 2. .. Kh1. The OP does not understand what a "solution" is and counts all 4 black promotion defenses as solutions.

Problemists call different defenses "variations" provided they require different unique white responses. Here is only the main line after 1. .. g1Q  since white can mate in several ways after other promotion defenses. Another correct way to look at "variations" is as "partial solutions". All partial solutions together constitute the solution to a problem (or endgame study).

easy puzzle bro, you can call it the "Kamikazee Bishop"

1.Bf6 - g7xf6

2.Kf8 - f5

3.Nf7#

The second one is also: 1) Sg5, Kg1 2) Sf3+, Kh1 3) Kf2, g2 promotes into queen, 4) Kg1 mate
