Unusual Checkmate

Comments:

• I don't think I've ever had a checkmate quite like this one!
• [as an aside, Kathee is winging her way to San Francisco to visit our daughter, so I am on my own for 3 days!]
• Note how the advancement of the Pawn in the F column prevents the black King from escaping check by moving to G7.
• The White Knight at G4 protects the White Pawn at F6.
• Basically I hemmed the opponent in including the Black Bishop
• Meanwhile, I had a great Pawn defense!
• The Black Rooks were likewise hemmed in with no where to operate freely
• As this developed I actually did not see this unfolding and was a bit surprise by the conclusion
• The keys:
• Good Pawn defense
• Invalidated the Black Rooks and Bishop but hemming them in
• Opening up the H column
• The Pawn on F6 protected by the Knight
