These chess puzzles require a lot of chess thinking in terms of strategy, moves, tactics and ideas. We are going to discuss a unique chess puzzle or composition. This puzzle was composed by Ottó Bláthyby, the Hungarian Engineer. It is a checkmate in 12 moves and we are going to discuss the winning move continuation for White.
It is not a necessary position which may appear in a real chess game. It is just a beautiful composition where your objective as White is to checkmate the Black King. Here White has just one Knight and a King whereas, Black has all his pieces. As the opponent (White), you need to find the best moves in which you can trap Black pieces and checkmate the Black king at the end.
Let me tell you the Black's and White's position in the Board. Black King in D5 and Black Queen in C7, two Knights are in B7 and A1, two Bishops are H4 and A6, Rooks are B4 and C4 and the Pawns are in B5, B6, C3, C6, D3, D4, D6 and G3. White’s King is in F5 and Knight in H5.
If you give a close look in the current positions in the Black and White pieces in the Board, you will understand the Black King is already stuck in between Black Pieces and this is the most positive thing for White. The Black King has only B7 and A1 squares to go.
You need to start with the Check the Black King and the first quite obvious move is Knight to F4 if you mistakenly play Knight to F6 then Black Bishop takes that piece and the game will end there. Black has only a legal move and that is King to C5.
Now you will play Knight to E6 to check the King and at the same time threatening the Queen. Black has to play King to D5. You take the Queen and It will be a check again. King move to C5 and you will pin the Bishop on A6. It will be a check again and the King has to move and play D5.
Now that you have eliminated the Queen and the Bishop, you should go back to the same order. So you will play Knight to C7 check King will play C5, you will play Knight to E6 check King will play D5, Knight will drop back to F4 check King will play C5.
You cannot pin the Rook o B4 if you do that you will lose our Knight by the other Rook on C4. Now if you look at the position of the pieces, you are back to the original position where it all started, just that you have eliminated the powerful Queen and Bishop.
Now you will go for the King to E4 blocking the D5 square. Now, what are the options Black has? It has already freed up some squares so it can move any of the pieces surrounding the King or at least give a check to White. But as you eliminated the Queen and the Bishop the chances become limited for Black to give any check.
So now Black can move only the Rook on B4 or the Pawn on D6, rest all the King surrounded pieces cannot be moved. Between those two pieces, Pawn will be a better option. Suppose the Black plays the Rook to B1, you can simply play the Knight to D3 and will be Checkmate because the B4 square is also covered by the Knight.
Therefore the Black is forced to play the Pawn to D5 which also puts the White King in check. Now you need to control the D6 square so you will play King to E5. Now, what can Black do here as there are no more squares for its King. But here is one more check move Black can play, so Black can play the Bishop to F6 for the check.
But if you are thinking to pin that Knight, it will not be a good idea as the King can get a scope to escape. So there is the logical move to play is King to E6. Black can play Knight to D8 check and you should counter with King to D7.
Now Black is completely helpless as it cannot give any more checks to White. So whatever move Black plays you should simply play the Knight to Knight to D3 and it will be a beautiful Checkmate.
