great exercise! while these may be the "best moves", are they the only good moves that black or white could have made to win??? At the least these are the moves a GM made, I suppose

Sometimes your puzzles depend on moves by your opponent that they may or may not make,sometimes the opponent makes bad moves that you cannot depend on in a game,so I don't feel to bad if I miss a few.

Good puzzle.  This position is actually quite common, so this is very useful :)

arrrrrrrrrrrrrgh, that was way too hard, I only got like 4 moves correct.

Decisive opening moves.

I recognised the setup for the Tarrasch Trap (interestingly, I was reading about it only last night) but it'd be bragging to say I worked it all out in advance.

As always, it's amusing to read the comments from people who think they know better than Tarrasch or Marco. 

So suggest something already!

Long One :)

very long one, however, i managed to solve it with no errors.

long tough one today

so very long

Anyone said easy?

took more than 4 mins

half way

Just lack 11.... Nd3 12 cxd5 Nxe1 13 Rxe1 Kf7 and 14 Bb4 or Bh4

Wowowowo! Awesome!!!!!!!

You can't solve 85%. It is how you say in mate in 4 I solved 3 moves

The puzzle ended there because white has just forced a piece win that black can no longer save with any defensive or counter measures.

Some of the toughest puzzles to solve are ones where the puzzle outcome is greater for the winning side than, with best play on both sides, it really should be.  Black had opportunities on moves 2 and 4 to remain only down a pawn, and probably be down positionally as well, but not losing a clear piece.

nice problem... I hope that the staff posts more problems like these.

nice but very long for a daily puzzle!
