and if (2Qh7) ? black has to move the bishop (white threats Qh8#) in f6 (if not Qxg7 mates or if Kf6, Qh8, Kg8, Qxg8#), but then 3Qg8+ Ke7, 4Qe6+ Kf8, Qf7#
First of off, you have the position a little wrong. Besides that, you missed 1... Qxf6 as the winning move for black. If white plays 2. Qxf6, then black plays 2... Rxe1#. If white plays 2. Qxe8+, then black plays 2.... Nxe8 3. Rxe8+ Kg7 and wins the game. If white moves their queen out of the way of the rook, they lose to Rxe1# because there is no way to defend the rook. Other words, white just lost the game.
Sorry if someone mentioned this already.
If Carlsen didn't see this easy to spot blunder, Qxe8 this still would have been better for black:
It is still an easy win for white.
This was the position, by the way:
Oops, I got in a hurry and missed another move by white:
In the final position, black will also lose the knight due to 5... Ng7 6. Qd8+ Ne8 7. Qxe8+. Still, the point is that Nf6+ is a blunder.
I'm actually starting to be more interested in what E-kuko posts here
Made you realy have to think
Thanks, E-Kuko. Your puzzle is very interesting.
2. Qh7 would have also worked I think
Why not white bishop take D5, king to F8, Withe Qween to H7 and next move white Qween to G8 mate. Is that not correct?
I'm not sure about this one...
And then the bishop on g7 moves
Why is queen to h7 not the 2nd move?!?!? Blk king cannot move out of the pending mate and nothing could block it. Nor could blk make any agressive move to stop the mate on white's 3rd move.
