How can I find games by titled players that had to deliver checkmate with knight and bishop?

Hi!

As of late, I'm looking for games played by titled players in which one side had to deliver checkmate with knight and bishop. Can anyone show me a solid and reliable way to find these games, for example in the online ChessBase database?

To be clear, I'm not asking for a list of games, or the link to the ChessGames site. I'm asking for a search method that demonstrably works.

Thanks in advance!

Why should they be titled? Most +1600 players can do that easily. I have even won otb with 2 knights against a pawn.

I'll happily relay in DMs why, if you must know. But can you help me with the question I asked?

Here is a detailed, step-by-step guide. We'll have to do two separate searches: one for when White delivers the checkmate, and one for when Black does.

The Best Method: Using the Advanced Search Mask
This method is precise and will find exactly what you're looking for.

Part 1: Searching for White Mating with Bishop and Knight
Follow these steps to find games where White has a King, Bishop, and Knight and checkmates Black's lone King.

Open Your Database: First, open the database you want to search (., Mega Database, or a personal database).
Open the Search Mask:

Press Ctrl + F on your keyboard.
Alternatively, right-click on the database icon in the main window and select Search.
Reset the Filter: Before you begin, it's good practice to click the Reset button at the bottom of the search mask to clear any previous search criteria.
Define the Material:

Go to the Material tab.
In the White section, define the exact material:

Click the King icon once.
Click the Bishop icon once.
Click the Knight icon once.
The display should show: K B N
In the Black section, define the exact material:

Click the King icon once.
The display should show: K
Crucially, make sure the "Or" checkbox at the top is unchecked. This tells Chessbase to find positions with this exact material, not positions that contain this material plus other pieces.
Specify the Checkmate:

Now, go to the Position tab.
In the "Also find" section, check the box for Checkmate.
Specify the Game Result:

Go to the Game Data tab.
In the "Result" section, check the box for 1-0. This ensures you only find games that White actually won, filtering out any games that might have ended in a draw by stalemate or the 50-move rule from this position.
Run the Search:

Click OK. Chessbase will now search the entire database for games that ended with White delivering a checkmate with a Bishop and Knight against a lone King.
 
Part 2: Searching for Black Mating with Bishop and Knight
The process is almost identical; you just swap the material and the result.

Open the Search Mask (Ctrl + F) and click Reset.
Define the Material (Swapped):

Go to the Material tab.
In the White section, click the King icon once. (Display: K)
In the Black section, click the King, Bishop, and Knight icons once each. (Display: K B N)
Again, make sure the "Or" checkbox is unchecked.
Specify the Checkmate:

Go to the Position tab and check the Checkmate box.
Specify the Game Result (Swapped):

Go to the Game Data tab.
In the "Result" section, check the box for 0-1.
Run the Search:

Click OK. This will find all the games where Black delivered the mate.
Alternative (Simpler but Less Precise) Method
If you just want to find games that reached this endgame, even if they ended in a resignation before the actual checkmate, you can simplify the search.

Open the Search Mask (Ctrl + F) and click Reset.
Go to the Material tab.
Set the material for one side (., White: KBN, Black: K).
Click OK.
This will give you a much larger list of games. The checkmated games will typically be the ones with the highest move counts in the resulting list, as the player with the lone king fought until the very end. You can sort the search results by clicking the "Moves" column header to find these games more easily.

By following the first, more precise method, you will get a perfect list of games to study this classic and beautiful checkmating pattern.

I would bet most players below 2100 could not demonstrate the mate. As Some of the the best players in the world have also failed this test.

That was Google AI. And it says your welcome.

I am not sure why most people know about these tools, but do not use them for these kind of questions.

That might actually be an interesting question to ask Google AI. See what it comes up with.

It has no idea, that is. Good.

Like I said in the first text, this is what I didn't ask for.
