Great moves puzzles
Black resigns in 5 moves. Start with a great move and keep exerting pressure on Black's Queen and King.
Although 2 pawns down in material, White's King is reasonably safe and White's Queen-Rook battery on the g-file is threatening. But White needs help from a third piece and a great move to make an effective attack and take a material lead in 7 moves.
Although a long puzzle at 11 moves, it contains 5 great moves to find. In this position Black is up two pawns of material. But there are no immediate threats to White. On the other hand, White's pieces are well connected with a couple of long range threats. Can you find the great moves that will end in Black losing its Queen?
White's c-pawn and d-pawn look threatening. Can you find some great moves to support their advancement?
White and Black are equal in material and both have threats on the two middle files. Both would like to clear their respective file of their opponent's pawn to control the file. Can you take control of the e-file and prevent White from controlling the d-file? Find a great move to achieve this.
Clear the diagonal between the White Queen and Black King. Finish the puzzle by finding a nice pin to win material.
In this position Black has a +3 material advantage. But the eval bar is 2.2 in White's favour. White finds 4 great moves and a brilliant move to end the 11 move puzzle with both Queens off the board and a +3 material advantage and an eval of 4.1.
White plays with 100% accuracy and forks Black 3 times in this 5-move puzzle. How does Black play these forks and keep the material equalized?
You have a tough opponent who plays with an accuracy of 98.0 in this 10 move puzzle. Can you play like Stockfish to capture the Black Queen and both Rooks?

The first puzzle is already suspicious.
1. Rc8 is the most obvious, boring move in the position, the first move anyone would think of (and play) in a blitz game. It would me much better to start the puzzle on move 2 and end on move 4.
For the latter the reason is that 5. Rc6 is not the only winning move, and probably not even the best. Many moves win just as much, like Rc7+ or Ra5 or Ke5. Depending on the depth, Stockfish either prefers Ke5 or Rc7+ as the "best" move, but only by a slight margin.
