Another Q sac 1.Qh6+...Nxh6, 2.Rcg1+...Kh7, 3.Bf5+...Kh8, 4Rxh6#.I liked the way the Q sac forced black N to take Q,now you could use your R to check,forcing Kh7,now you had use of your Bf6, to force Kh8,and then the final blow Rxh6#.Could see mate from begining,nice set up.Good day Chess head's

nice!

interesting! :D

At first I was looking at 1. Rxh6+, couldn't make it work, and then realized the importance of keeping a rook on the h-file the entire time, keeping the knight on h6 pinned.  For example, if 1. Rxh6+ Nxh6 2. Rg1+ Kh7 3. Bf5+, then the knight is free to play 3...Nxf5 because it is not pinned, as opposed to the puzzle solution.  Once I realized all this, I got it rather quickly.

sunday already,last page

interesting.. took a while to get it

Takes a little careful thought - good puzzle !

Very nice queen sac. I tried first with the rook, but it'd break the logic really.

More puzzles please! :D

well then

It is a matter of finding the first move. The rest is forced.

A beautiful one. Thanks, Chess.com!

wow...impressive...

1. Rcg1, with the immediate threat of 2. Qxh6#, looks like it ultimately works, but because it is not a check, it allows black time for stalling/defensive moves beginning with 1...Qxc2+ that should delay mate for more than four moves. 

nice...

Good one

Good one.

solved in 2nd time

Nice one.

Not too difficult

First time doing it without making a mistake :D
