Difficult one.

Tarrasch trap

Why did the solution end when it did...with no checkmate shown? Is it so obvious they didn't show it? Help please!

Wouldn't this pull a win instead of a draw?

Edit: Nevermind, Queen to h8 or h7 is checkmate.

what happens if black takes with the knight on move 4 instead of move 5?

This puzzle is a well known trap out of the Ruy Lopez Opening (I don't remember which variation...), where black plays 0-0 which is a mistake, losing a pawn. I believe all these moves are forced.

11. C4 was devastating!  Eleven (11) deep!  Thanks for the lesson!

nic one....good puzzle

Easy. First.

Wow, hard one...

This is a known trap, black has to take on d4 before 0-0.  I've actually played this in a game, so I got the puzzle really fast (although I was unaware black could avoid the loss of a piece for so long).

long... indeed

can somebody explain this?

In the final position, Black must either lose a piece or give Rook for minor piece in a quiet position. Between masters, the win is then just a question of technique, but it would take a long struggle before it was done. Marco resigned on the spot, knowing there was no realistic chance of saving the game.

I personaly think that they should try to include a few more puzzles like these, instead of having the large majority being games of "mate in (2,3,4)". It makes great variety for the daily puzzle, and the variety is a good benefit.

I second that notion.
