Very obvious but good for an easy problem.

another Q sacrifice

Takes few minutes to figure out the first move ( queen sac). Then the rest is easy :
Qd5+ NXd5
Bg4+ Ke5
Rf5+ Kd4
Rd5+ Kc4
Be2+ Kb4
a3# halleluya
2 stars

Very obvious?

Wow, I am impressed that you found this to be very obvious.

I had a hard time working this one out to the end mostly because I had a hard time visualizing the last move. I thought 6.a3 allowed Ka5, forgetting that my rook covered that square.

On top of that, White had more than just one candidate move. The solve rate (63%) shows that it belongs in the "easy" section, but that it wasn't "very obvious" to many.

Shulman-Feldman, Riga Open 1986

It took me a while to find the root game. The source is wrong. Shulman, who never won a FM title, had a fantastic result, tying for first ahead of Shirov, Tal, and other GMs.

Here's the complete game.

[Site "Riga"]
[Date "1986.??.??"]
[Round "?"]
[White "Shulman, Vladlen"]

[PlyCount "43"]
[EventDate "1986.??.??"]

Interesting puzzle

I looked at the bishop giving check first but that didnt lead any where. Then I thought about a queen sacrifice and hey ho it all starts to unravel . Yet again a queen sacrifice starts it all!!!! And I still didnt think to look at it first move.

I enjoyed this one

Without the queen sac the black king will escape via f7. It also deflects the knight, and now the bishop check cuts off the f file by clearing it for the rook. After that the natural checks are pretty easy to find, and ending with a pawn mate is always pleasing.

Fun...

There are only two checks to lead with, and (especially as a puzzle) it's not hard to think 1.Bg4+ Kf7 is going to let Black's pieces get in the way of mate in 6 so 1.Qd4+ seems like the right line to analyze first. A few easy decisions to make about which checks to follow in the later moves, but its just a matter of looking for the most forcing moves first. Still I agree with fezzik, it's hard to anticipate what will happen until you've put some work in.

Nice puzzle

Not very obvious for me as I missed on my first attempt.

yet another Q sac

I agree with some other posters about the frequent Q sacs. I'm only an intermediate player, and have nothing to brag about on a chess board, but these puzzles are made easier, whether 2 moves, or 6, such as this, if you approach them thinking the Q sac is involved. So I do, and I keep doing well at such puzzles when a regular puzzle book would stump me more often. This is not a complaint, just an observation. I am thankful for the puzzles and still delight in doing them. Considering my rating, perhaps I need to employ more deliberate Q sacs in my game!

@gearbreaker

No I think that the problem with players of your rating level is that they sacrifice their queen rather too often

Also note that I found that the first move was forced immediately, but wasn't predisposed to looking for queen sacrifices. I looked at the position just as I would in a normal game. The only thing that took a few seconds was figuring out the rest of the continuation, but that's not because I was looking especially for queen sacrifices.

Here's the difference:
The beginner thinks he can't sacrifice his queen, but often does.
The master knows he can, but rarely does.
