WHITE PLAYS AND WINS
 
I played the first move of this sequence a few minutes ago in a blitz game, then I messed up with the order of the moves. Try to do better than me. White moves and mates (however this is not a 100% line, you'll see why after the puzzle). Difficulty: 2300/2400.

BLACK TO PLAY AND GAIN ADVANTAGE
This is more like an exercise for your strategical skills. As you get better in chess and you have more experience, you'll understand material isn't everything in a game; there are other aspects which may be more important, depending on the situations: king safety, development, position of your pieces, weaknesses, strenghts, open files/diagonals and pawn structure (this may surprise the lower elo readers, but sometimes pawns may be stronger than entire rooks!). In this puzzle, you have the opportunity to damage two of those aspects, creating a long term weakness that may give you the win (in my case, it didn't ahah). Difficulty: 1900 (much easier with the hint). 

Don't forget to tell me what you think about the puzzles! Good bye!
