Mating Net puzzles
Capture all Black pieces leaving King and some Pawns and promote the e2 Pawn to Queen. [A personal note: These kind of puzzles are GM level because GMs are expected to judge whether to ignore an opponent's attack on a valuable piece to gain a tempo. You'll notice that White already sacrificed it's Queen for two minor pieces and a dangerous passed pawn on e7. To solve this puzzle you'll need to keep thinking like a GM.]
This puzzle was somewhat difficult to solve without any help whatsoever
Unfortunately, I can't include any clues with the puzzles because others don't like help. I suggest you use the hint feature whenever you get stuck. Just remember to look for forcing moves in the middle game whenever possible. That means threaten your opponent's high value pieces with your low value pieces to kick them away with tempo. For that reason, usually Knights and Bishops lead the attack to damage pawn chains or the pawn wall in front of the opponent King.
Promote the b-pawn to Queen.
