Probably because Marco didn't fancy playing a pawn down in a clear position against Tarrasch, and hoped to find a saving resource somewhere in the ensuing complications (which are far from clear unless you have seen this before).

predictable!! :P

should i call this a puzzle or a long game. hmmm

Definitely Long.

SZ.

couldnt get the last move

What happens on 3...Rf8xd8 ? How does White wins material on 3...Rf8xd8 ? Because the game continuation will not work with 3...Rf8xd8

Retifan found it:

3...Rf8xd8 4.Nxe5 Bxe4 5.Nxe4 Nxe4 6.Nd3 f5 7.f3 Bc5+ 8.Kf1!

too much for phillycat, but thanks anyway! MEOW!!!

tough one indeed.

I got all the moves right, don't know why they were right, except for a few.....does anyone know how it finishes out?

jeez, so many moves

THIS IS THE LONGEST PUZZLE I EVER DID>-< *-* SÒÓOOOOOOOOOO LONG #.#

I got no moves right. I solved it by trying all possable moves until i would get the correct one.  When it told me I had solved the problem, I am not sure what got solved.  For those who find the puzzles too easy may I suggest run and butt your head into a brick wall, repeat 2 more times and you may find the puzzles more challenging. 

11 moves out from a typical-looking opening position?  Man.  It's Saturday, all right. X_X

long but easy i want hard!!!!!!!!!!!!!!!!!!!!!

what the heck is this one. its looks like a normal game

brrrrr...

pretty straight forward

holy crap daily puzzle is  usually a 4 move checlmate...

nice lesson!!
