My opponent resigned before I did

Am I missing something?  Doesn't 3 Bxf7+ work there too?

Looks like it does indeed

In the first diagram I want you to show another solution possible. It is much more complicated and does not lead to clearcut victories as the other moves, nevertheless. Hope it is correct. In the second one a game I resigned in a moment of panic having miscalculated, while I was winning the game. At that time: , now .

after nxb,rxr+,Qxr.......or, nxb,rxQ,rxr=white is ahead

@EddySallin: What you say is the main line. HicetNunc added the move Re7, I added the move Re7: to his line. Best move is the main line obviously.

Sorry,maybe i was not clear.....Where ever black Q was(say d8,Qxb and white lacks a winning answer.....or if the Q, was on 6th rank the Q, can X b.+... Blacks Qa5 is the one move that creates a winner into a loser, and sets up the b.+s that allow white to win.

@EddySallin: I was ahead in material and I thought that the combination was good. I knew the coverage of my back rank the moment I played Qa5:, but only two moves later I had forgotten it. It is only now that I see that after b6 I had to lose. The resemblance with the combination of Shivsky becomes bigger and bigger. :-)

Before Qa5 did u have a winning game ? Where was your Q. located before Qa5 ?

A winning game? Hmm, at that time became it difficult. My queen was at d2, hence the move Rd8 pinned the pawn that defended the knight. The next move was not that obvious - at least now it is clear that my combination should have gone wrong.

I could have played c3 I suppose. Required is that my queen is on a black square to prevent any action from the battery Re7/Be6.

But maybe could I have played 26. Ne6: Re6: 27. Re6: fe6: 28. Qa5: Bd4:+ 29. Kf1 Bf6, which is more or less equal. I think it is in blitz easier to play with the queen, because you have less pieces to coordinate and it is very mobile and can give a long range of checks in open positions.

Qa5 is an outright lost. Bd6+,re7(to block)allows bxr+,k moves to a white square,bxp+ and your Queen is lost.    My point is the odd position. I agree about blitz w/ Queen, plus perp. check can sometimes bail u out and it's easier w/ Queen.    Have a good day.

@EddySallin, I can not understand the moves you make and do not know what the position is you are talking about. Bd6+ is not possible in any circumstance.

Oh, now I understand. I was talking about my game, you were talking about the game of Shivsky. You are completely correct in your findings about that game. That queen has never been my queen, because it was not my game.

For reference/clarification: In the original game which this post was about, I  believe I moved my Queen from Qb6 (from where Qxd4! looks like the move I missed)

Poor guy probably focused on Qe3, Nxd5. (cliche voice) But sometimes the best defense is a good offense! Hur hur hur

Very funny post indeed! To be fair, if white wanted to resign but, say, the rules didn't allow for resigning, he wouldn't play Bd6+ (else he wouldn't have wanted to resign).
