White to move. Mate in 4.

Hey, Charlie.  Cool puzzle.  The key is to make sure that black Rook doesn't clear the pawn and create a check to the white King.

How is your wife doing?

nice

 Thanks

Nice job Charlie... Thanks god I solved it , meaning that I learn by playing against you. I think you should put there the acknowledgments for the defeated player, though .

See you during the weekend, hopefully.

Perfect.
