Red = Normal puzzle

Pink = Pink Panther Powerful

Black = Special Mate in 3

Green = Special Mate in 4

Bc3

Bd3.

You should add some pieces for Black. They have so few defenders. I just looked for a pattern in the pieces and found one.

Sorry bgop but after 1.Bc3 black can defend with 1...Rxa2!!

Congratulations Spotlion. You found the answer. I think black needs more pieces, but I think I should make an easy puzzle sometimes. Puzzle 48 is going to be a lot harder... I hope

Adriandmen, you made a lot of sacrificial key huh! 

Reviewing your 2-mover puzzle from 41-47, I notice that your key move is always an explosive sacrifice!

Yes Asorski. In chess I always play agressive with alot of sacrifices, also my style of composing . But sometimes I try something else, like a waiting move etc.

Adriandmen,

Reviewing your work, your 2-mover problems no. 41-46, I noticed that most of your solution begins with an exlosive sacrifice!

In Puzzle no. 41, your key move is a Queen sacrifice but the other piece, a Knight actually threatens mate!

In 42, your key is a waiting move 1. Re1 which treatens nothing but wait for Black to make an opening/a weakness. I also notice the 5 White and 5 Black pawns on f to h-files. "How did the pawns get there"? was the careful critics asked. Don't get embarassed for this is normal to average composer. Look at me, even experts have some (or more) misfortunes. 

You know, a chess problem with a waiting key move is very hard to make. My advise is to keep on composing them. Soon you will get acquainted with how the pieces work together in a problem. Someday, you will find composing waiting problems as easy as ABC!

In 43, your key is again a Queen sac which threatens mate.

Problem no. 44 is another Queen sacrifice 1. Nb7! followed by 2. Nc5#.

In 45, first move is Queen sacrifice threatening mate by Nh5.

Problem No. 46 is for me is the finest among all your compositions. Why? because it carries the principle of a real chess problem: 

a. The key is excellent! First move is a Bishop to be followed by a Queen mate. You remember my excellent puzzle no. 41? The key is 1. Qa7! threatening 2. Nf2#.

b. The position is legal and no other solution is present. Only one key move can do the job! Chess engine indeed is a great help!

c. No useless pieces is present! You remember what I commented about your earliest puzzles? That this or that piece actually no function at all and should be removed? No. 46 is finetuned! Every pieces serves a vital purpose! For instance, Nh1 prevents Qg3# and Nh7 Prevents Qg5#. The pawn on h5 prevents 1. Qh6+. Black pawn at a3 prevents a Rook check on a2. The b3 pawn prevents ...Rxb4 defending the critical e4 square! I mean, the construction is simply amazing! I now see you Adriandmen transforming from a beginner to average to a more professional and oustanding composer!

All I can say is: "goodluck as you search the sea of ideas in this wide world of chess problem composing!"

Wow Asorski. I can see to your comments you really liked puzzle 42 and puzzle 46. Thank you for your review to all problems. I can really learn a lot from you. You can also see I like queen-sacrifices. And a puzzle with a waiting move is hard to make. A good composition is never ABC, because it needs alot of thinking  to make the least obvious move as the answer.

Thank you Asorski, for your honest comments and compliments,

~~ Adriandmen ~~

I mean puzzle 42 is an illegal position. "How did the pawns get there"? I asked. My suggestion is: avoid illegal position as much as possible and check the movement of your pawns.

Consider the following position: This is my original composition but change it later after I realized that this is an illegal position. Black cannot reached this position starting  from the opening array.

To reach this, Black must make 13 captures by the pawn. Considering that White still have 8 pieces on the board plus the captured pieces (13), it is clear that White has 21 pieces all in all clearly illegal.

I improved this one to make it legal. ( Please refer to my original chess problem no. 9 for improvement).

Again, always check the movement of your pawns.
