Puzzles needed for tactics trainer

Hi katonas. This is a tactic from one of my Blitz games:

The tactic: 

See if this works? 

katonas, another self-composed tactic:

See if this works too. White can try drawing it, but I think since Black's Bishop is also dark-squared, Black gets an easy win there. 

Even after 1...Kg7, black will probably still be winning because of his pawn advantage.

This might work:

I can only tag the mainline so this puzzle is incorrect but from the starting position it's black to play and mate in two, I would be pretty siked if it's used. So I Included a versions that is correct,

Tags: mate in two, sacrifice, clearance sacrifice

Here's another one from one of my games that I really like

My Tags: Mate in 3, Sacrifice, Clearence Sacrifice, Queen Sacrifice

Nice pawn endgame here, it's based on one of my otb games but i changed so many things to make it work it's more of a composition.

Black to move and win, white plays 1.Kb8-c7

I have checked with endgame tablebase and these are all only winning moves.

Also the variation 2.g3 Kxc4! (only winning move) could be a tactic

piphilologist, So what is black's next few moves?  Ah, I see.  Nevermind.

that was my point there is no use if he doesn't

the funny thing is metaknight, is that there is a better line after KB2 anyway:

...Rb8+

a) Ka1 Rc1#
b) Nb3 Nc4+ Ka1 Rcxb3+ Rb2 Bxb2+ Kb1 Na3#

Why isn't katonas active?

b) 3. Kb2 Rb8+ 4. Nb3 Nc4+ 5. Ka1 Rcxb3+ 6. Rb2 Bxb2+ 7. Kb1 Na3#

Those numbers really help.  :-p

Baldrick went for the queen.

How about this? (Note that black has just moved his knight from d7 to c5)

Yes, but 3... Rd5 practically equalizes the position.

This is an ambiguious puzzle. After 1. Bxc5 Rxc5, There is 2.Qa8, with Qc8 3. Qxc8+ Rxc8 4. Nd6 (Which leads to a bigger advantage as it actually wins material)

2. Qd8+ Bf8, where white doesn't have to play Nd6, as he has a huge advantage anyway, as after that 3...Rd7 or 3...Rd5 prevents white from winning material

And even in the starting position there is a huge white advantage anyways

For example, in most lines Bxc5 will happen so there is no hurry, because all moves will eventually win like moving your rooks out to active locations or g4 and h4.

This is from a game I'm currently playing, and we're currently on turn 24 (4 on this puzzle).  It's a forced mate, but my opponent may not know this.  I'm not sure if you want forced checkmates, but here is one.  Any ways, the hard part is the second move, because taking the rook with the knight is very tempting.  This is actually what I had planned but realized the second move is much better.  I sat down at my board with pin and paper and worked out all possible moves.

Board is flipped since it's for black:

Probably my best mate so far, although it's technically not finished!

I don't think Kd1 is forced, so you might want to start with the Qxc4.

I'm having problem with the diagram.

Can someone post this for me?
