I train a few tactical exercises

I start with a few tactical tasks. I'm going to use three different stages, and the difficulty of the tasks with levels rising. Let's go!

Level 1: White checkmates!
1)

2)

Level 2: Black is matt!
1)

2)

Level 3:
1) Black wins.

2) Black wins.

The first four tasks are the book "Chess" by Laszlo Polgar removed. The book has an unbeatable price-performance ratio.
The two last I have taken from the book "The Chess Cafe Puzzle Book" by Karsten Müller. I like the scheme of the book very much.

we come to the solutions. I write them in the color of the background, so that you so can not just read. By highlighting the text then however, visible.

solutions

levels 1 and 2 are simple, precise calculations. At level 3 an idea is helpful.

1.1) 1.Txa6 XA6 2.Lg2 TC6 3.Lxc6 #

1.2) 1.Dg8 Txg8 2.Sxg6 xg6 3.Th4 #

2.1) 1st .. 2.Kxg5 g5 Rg8 and now:

- 3.Kh6 DH3 #

- 3.Kh4 DG4 #

2.2) first .. Txh2 2.Kxh2 DH3 3.Kg1 Dg2 #

3.1) The idea is that if we hit the jumper, the white base range of weak! After that we need to get only the other tower of the f-file. So

first ... Txe6 2.Txe6 3.Dg3 h4 g5 4.Txh4 Qf5 5.Te1 Sg4

3.2) Again, one must use the white base line. The tower is tied to the basic series, when the King is in the corner.

first .. DD4 2.Kh1 Df2!

I hope you have enjoyed the tasks.
