Some of you have asked me about chess on this forum ... I had to think of that yesterday, when I had to put together tactical exercises for children. If you want, you can try them. I have 5 different levels of difficulty with 20 exercises each.

Here is the first level: It is pretty simple. It presupposes that you know the rules (and the value of the pieces) and basically tests your ability to spot mates in 1 or pieces that are not sufficiently covered.

Weiß am Zug means White to move.
Schwarz am Zug means Black to move.

17 the smothered mate by a pawn is nice.

Weiss vs. Schwarz played to a draw:

Wow. Most boring game ever.

If anyone wants to post their answer or has a question, you can do that here; I will correct them.

The second level is still pretty simple: It tests basic tactics (like double attacks or discovered attacks) and mates in 2.

Wow. Most boring game ever.

The 1890 game is more boring than the 1883 game. The 1883 game is a draw, but the symmetric end is elegant.

Wow. Most boring game ever.

How do you piss off a French player?
You take on D5.

You mean Bxf6

You would have to specify which rook, but from your comments I can tell that you mean Rfxf7.
#6 1. Bg2#
#7 1... Nxd5
#8 1... Nf4#
Which knight?
#9 1. Bh5#
#10 1... Nxd4
That's not right (That move would, in fact, lose a piece)
#11 1... Bxf1
#12 1. Rxh5
#13 1... Qh2#
#14 1... Qxg2#
It's white to move

1. Qxe5+ Qxe5

There's a better solution.

In a typical game of mine the one to make less blunders wins.

Good! Just one mistake. I will post the next level later.

 

[Bitmap]

The next level is in a different format ... Putting the pictures from level 1 and 2 into a text document just took too much time and I had some trouble sorting out how my new version of chessbase works (they managed to make it worse than the previous versions).
The side to move is indicated by the white or black circles next to the diagram (on the right side).

Level 3 features a mixture of motifs at work in some short combinations (usually around 2 or 3 moves)

 

[scrabulista]

In their 5th encounter (1895), Weiss finally beat Schwarz.

 

[Bitmap]

For good measure (and your personal benefit), I will post the rest of the exercises.

Here is level 4:
