- I find chess puzzles like these annoying - - because a Chess newby could put the king in by sacrificing the queen and take it from there - then when the black king tries to escape - just accidently every possible square it being attacked or controlled by various white pieces - what white skill / what white luck / what coincidence / - well if one is smart enough to play a black who unluckily or unskillfully lets you control so many pieces around his king around hit KING - and all his pieces are out to lunch and on vacation = = = well do you really need to study a puzzle like this ? should one not study more advanced material 

- on chess analysis - I would say that black is playing on whites side - and possibly got paid to throw the game

===== I once saw a book about chess puzzles that had a special name - there was only ONE possible solution for check mate - - and if there was more than one solution then it could not be considered one of these puzzles - well I found these ones interesting - but these puzzles which blatently show the solution ( like how long / really how long - does it take before anyone and everyone ( including chess newbies thinks - well I guess I should sacrifice my queen and put the black king in check - making the black king defenseless ? ) -- how long 5 seconds 10?

Honestly, I have no idea what you're talking about.  I thought it was a very nice problem.
