Every honest chess player would prefer a queen sac followed by a smothered mate. This version is lacking the aesthetic quality.

Ah the beauty of mating on the back rank! Nice one.

But the Knight prevents the King from capturing the Queen.

even if this is faster, i would play smothered just because it rocks :D

Yeah, smothered mate looking setup

Na6, Ka8, Qb8+ Rxb8, Nc7# is a way cooler mate.

seriously, why does queen c7 not work? been looking at it for couple minutes now, don't get it.

Excellent... Fifty points for Gryffindor!!

sweet

nice

Lol...I think 95% of us thought this was smothered mate.

very nice!

Good exercise in knight and queen combination.

your solution is not good.

The good one is :

Qd6     Ka8

Nc7     Kb8

Na6     Ka8

Qb8      Rxb8

Nc7

this solution is good but there is a better one:

Qd6+    Ka8  -   Nc7+  Kb8   -   Na6++   Ka8   -  Qb8+  Rxb8   -  Nc7

Soyez s\'il vous plait pertinant, efficace et gentil !

your solution is not good.

The good one is :

Qd6     Ka8

Nc7     Kb8

Na6     Ka8

Qb8      Rxb8

Nc7

There is also 3.Na6++ Ka8 4.Qb8+ Rb8 5.Nc7#, isn t it?

1. Qd6+, Ka8 2. Nc7+, Kb8 3. Na6++, Ka8 4. Qb8+, Rxb8 5. Nc7# is yes, definitely much more elegant.  I cater to the idea that serious chess is a clash of wills and egos, and the cold-blooded ruthlessness with a forced smother mate in 5, with the opponent absolutely helpless, is much more in keeping with the spirit.
