Those who understand my teaching approach will be aware of the emphasis I put on endgames. The September clinic was devoted to this phase of the game and I found the following position particularly interesting (see diagram):
In the game Black played 40...Nc5 after which 41.Kd2 Nxa4 42.Kd3 Nc5+ 43.Kc4 a6 44.bxa6 Nxa6 45.Kb5 Nc7+ 46.Kc6 Ne8 47.Kxb6 led to a draw because White can sacrifice his bishop for Black's remaining pawn. Accordingly I think that Black has better chances by trying to keep the queenside pawns on the board and force White's f-pawn to move to a light square; my line is 40...Nc3 after which 41.Kd2 Nd5 42.f5 Nf6 43.Bh3 g5 gives Black definite winning chances.
I should repeat my recommendation that nobody can go far wrong by spending some time studying endgames, and Tiger Chess has a 160 week course on this with many hours of video lessons on the endgame.
