These must have taken you a long time to make. Me and some of the students at my chess club like to think up chess puzzles, too. It can be great fun!

Hey, maybe you could publish a book...

Well, at least they seem to work.

But, as I've said many time before, Composition is a discipline with rules, if you want to make it a serious hobby, it would be good to stick to these rules.

Two things:

1) You have to give a stipulation for each position, what is the objective? eg. Mate in 3 moves, or White to play and win, etc. The solver must know what is expected.

2) In compositions of this type, you should not use promoted pieces (in studies you can). Eg, in your second position you have 3 Rooks. Composers call these OBTRUSIVE pieces. You  have to avoid things like that, or things like 2 bishops on the same colour.

Composing is a rewarding passtime, which can give hours of pleasure to you and your friends, and if you're any good at it, you can even enter competions, or get your work published in newspapers or magazines.

got to have a few flames here mate, here

You have to make sure that you have a single solution for each puzzle. For example:

Puzzle 1: 1. cXb8=Q is equally good, and 2. Qh1 also checkmates.

Puzzle 2: You gave a 3-move checkmate solution, but 1. Nb2+ 1. Ne3+ and 1Nf2+ all lead to a 2-move checkmate.

Puzzle 3. 1. exd3+, exf2! and white is losing.

nice

Ah, in puzzle 1 there should be a pawn on h6. My bad.
