I have a couple candidates from a game:
And from the end:
For this one I know the first post says it must be at least two moves, but I bet some people would struggle with that mate and learn from it.

ClavierCavalier, unfortunately the Fischer v Spassky problem is ambigous as 1…Nf6 2.Qe5 (+6) is an alternative winning line.
Thankyou Spieler999, 1…Na5 2.Qa5 (+1.7) and 2.Qb3 (+0.46) isn’t enough of a difference in gain, so I’ve started this tricky puzzle 2 moves later. 124th puzzle http://www.chess.com/tactics/server?id=468375
For similar reasons your variation 125th puzzle also starts later http://www.chess.com/tactics/server?id=401415
Thankyou Powerlevel_9001 for the 126th puzzle http://www.chess.com/tactics/server?id=436681
Now summer holidays are over, I should catch up over the next week or so.
ARGUING WITH FISCHER?!?!?!?! :-p
Oh goodness! Page 24's gonna take a long time.
And now another one coming up on page 26....
This puzzle has 3 variations, although the third isn't worth a TT puzzle and is never played (or I just hope so 
). Two TT puzzles arise from this one.
As White is already +2 up by material, you could try adding some pieces around and also maybe in the a-file to prevent ambiguous promoting lines.

for the first one, removing the pawn on g2 solves the problem.
for the second one, Re4 (0.00) vs e5(+1.05) is not enough?
How about puzzles involving underpromotion such as this:
This is a position known as Scossi's Mate. Note that since Black' pawn is at the 3rd rank when f2 is played, any active defenses by Black on the checks such as moving to the f-file early, result in Re7 played with Rf7 and the capture to follow, drawing or even allowing White to win. The Rook move to e5 allows White to stalemate the position should Black play f1/Q?? by playing Rf5+ Qxf5 DRAW.
was not sure but will attempt to find some different puzzles as well or at least post some games in which tactics played a large role in creating the wins.

spieler, if you look at the first post of this threat, it has to be atleast like 2.15 or somehing idk think was over 2 though, 1.etc isnt enough unfortunately.
hm, ok. i think you should not be too strict here as e5 leads to a clear advantage for white, but it is up to katonas to decide.

Ah... ;), but the queen pin is more awesome and will piss everyone off when they get it wrong, which is what TT is all about

Unfortunately I missed this forced mate!! I only realised it on the game analysis afterwards.

Ah... ;), but the knight mate is more awesome and will piss you off when you try the queen pin, which is what TT is all about
http://www.chess.com/echess/game?id=56889900, starting with 28... Qb2?
The game's not over yet, so I haven't seen the computer analysis yet, but I think it's solid. Tell me if I missed something...

TT is all about finding the best move, and which case 21. Nxa7# is the ultimate move of this game.

You missed two things but fortunately white still wins. Firstly 31...Qb1+ 32.Kh2 Qg6 fails to 33.Qh4+ Kxg7 34.Qh8#
Secondly 31...Qc1+ 32.Kh2 Rxg7 33.Qh4+ Qh6 34.Rh8+! also wins for white
Thanks, I guess black can delay too with a queen check before ...Rxg7, and push mate back one move. But I think it's still forced mate. My opponent went on vacation with two moves left, but I'll follow up here when I get the analysis.
@LegoPirate there is only one knight at that stage. Although the first black move is probably the most dodgy.
