Yeah, that one was pretty obvious.
In the meantime, I'd like to post my first "puzzle". It's not really a puzzle, it's one of the most famous games in the history of chess, or more pricesely, the ending of that game. It's called the "immortal" game, between Andersen and Dufresne in 1852. One of my favorites, the one I read about around ten years ago for the first time
As you can see, the next move of the black is check-mate.. but! white can win.. but every move has to include a check. It's a mate in five. Can you guess the winning combination? it's pretty easy..

The white f6 pawn moves to e7
The black c6 knight kills the e7 pawn
Then the e1 white rook attacks the e7 horse
The e8 black king moves to d8
Finally,the a4 white Queen moves to d7
Mate..
or I made mistakes?

.. and the response is

remember, you have to check the king with each move..

White: E1-E7
Black: C6-E7
White: A4-D7
Black: E8-D7
White: D3-E4
Black: moves King somewhere (out of check from Rook)
White takes the Black Queen? E4-F3
ok I don't know further, or was it the wrong way?

It's good thinking, but taking the queen isn't your priority. You want to win in five moves
The first two are flawless, the third.. you've selected a good piece, but you can make a better move with it

Oh man I love this match
Hint: You need to be ready to sacrifice one or more of your pieces for the glorious mate. All the moves are forced for black. You need to be accurate. One mistake in the five-step combo, and you'll get mated.

Almost perfect Ash, you're becoming quite a chessmaster here 
But
d3 b5 + leads to
c7 c6
Which screws up the rest
A better move is
d3 f5
and from there, the way you answered.
Very good anyway! I'm impressed

So it's something like this:
E1xE7+
C6xE7
A4xD7+
E8xD7
D3-F5+
D7-E8
F5-D7+
E8-F8 or E8-D8, doesn't matter
A3xE7#

Hi all.
So, how did you solve my previous puzzle? It wasn't a hard one I think.
P.S.: Good match, Ash!

It's seems like I'm again too late  . First, Asheera was right, because after 3.Bb5++ black can't play 3. ... c6, because, they are double checked from bishop in b5 and rook in d1, but you, Doomforge, were right in the another way, 3.Bb5++ don't win, because it will be 3. ... Ke6! 4.Bd7+ Kf6* and black wins .
Second, why here isn't writed more variants? Example: 1.Re7*+ Ke7* 2.Qd7*+ Kf8 3.Qe7* (Be7*) or 2. ... Kd7* 3.Bf5++ Kc6 4.Bd7* or 3. ... Ke8 4.Bd7+ Kd8 or Kf8 5.Be7**. What can do white after 1. ... Kf8 or 1. ... Kd8? Black still has an extra knight and may can do a mate?

right, I forgot about the rook Oh well, even the best of chess players make stupid mistakes sometimes. The point was it's not the best move around. As for "other combinations", they are possible perhaps, but the mate in five is actually well-documented and I didn't have to watch for other possibilities. Yeah, I'm kinda lazy.
Next puzzle soon, maybe you won't be late this time.

Ok, Doomforge, after 1. ... Kf8 2.Re3+ and 3.Rf3 wins a queen and maybe a game (example black could sacrifice his knight to b4, being able to take your rook in f3, or simple move with a knight in the e5 - it will be very complicated). About your variant, why after Kd8*(black), Bf5+ black should to go Ke6, they simple can take a bishop in f5 with his queen! Then white can't Qd7+, because of Qd7* Rd7* Kd7*, black has more a rook and a bishop, also f2 and g2 squares aren't good defendet ? It's seems like, that black can good defend in this position .
