Black missed 1...Qa1+ 2. Rxa1 Rxa1+ 3. Qb1 Raxb1# or 3... Rbxb1#.
White missed 2. Qxf7+ Kh8 3. Qxg7#.
Black missed 2...Qd1#.
Remember, both sides have a weak back rank. Otherwise 1. Qxb7 would be a really nice move.
Since Bryan681972 already pointed out the mechanics of the failings of this puzzle, I will allow myself to be a little more judgmental and (in the words of The Simpsons' Comic Book Guy) say: worst puzzle ever!!
Edit: This is regarding the puzzle Vasu1613 posted and not the original chess.com puzzle.
Interesting puzzle. Not a forced mate, but if I'm not mistaken, the only way out for Black is by sacrificing his Queen, and what a cowardly thing to do that would be!!
Mate is forced, but can be extended for another move. Sacrificing the Queen doesn't help, eg 1. Qf6 Qe6 2. Qd8+ Qe8 3. QxQe8#.Mate can be extended to 5 moves by not taking the Bishop.1. Qf6 Rg8 2. Bxf7 d5 3. BxRg8+ KxBg8 4. Re8+ QxRe8 5. QxBg7#
On 1. Qf6 Rg8 2. Bxf7 d5, quicker is 3. Bxg6+ (3. Be8+ or 3. Bxd5+ also work) Qf7 4. Qxf7#.
Quite right, overlooked that in my haste!
easy one, but i still don't understand why the picked up piece isn't where the cursor, but with 2 squares under it
Does anything prohibit black from not taking Bishop at f7?
Something like taking the other Bishop instead for example
If black plays 2...Bxh6 instead of 2...Qxf7 then any of the following moves also result in checkmate in four: 3. Bxg6+, 3. Be8+, 3. Bd5+, 3. Bc4+, 3. Bb3+. Those moves force 3...Qf7, and then 4. Qxf7# is checkmate.
