I know all the puzzles are Very easy, but I can do hard ones also, and if you doubt that, just look at my tactics rating. I hope the puzzles were fun and/or instructive (depending on your rating)

The endgame problems were cool. Always good to practise those. Good job and thanks.

I played 1...Kh8 in the pawn one, apparently I was wrong 

Any legal move draws in the pawn one. :P

Also, on the K+Q v. K problem, it tells me I am wrong for playing a mate in 1 (Qd8 instead of Qf7). That's why these don't make good puzzles. There are lots of positions in the solution where white has several moves that are equally good.

Yeah, there are also multiple ways of moving the king up.

they are ment to be reminders of basic ideas

But it's not a good way to do a reminder if the solver is being told he is wrong for playing a move that is as good as the move made in the solution. That's just frustrating for the solver.

I will add variations next time.
