    The Damiano Defence 
    (Knight Capture):
    Black’s Worst Choice
    By
    Michael Quigley
     
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5
     
     
     
    Although, not technically Black’s
    worst choice (3…g5 is mate in 5) it is
    bad enough to have this title, for
    Black’s first move after our initial
    position.
     
    White responds with an immediate
    check on the Black King.
     
    4.Qh5+
     
    Black has 2 options:
    •  4…g6 blocking the check section
    1.1).
    •  4….Ke7 moving the King out of
    check (section 1.2).
     
    Despite Black’s choice, White should
    play the same move.
     
    5.Qxe5+
     
    1.1
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    g6 5.Qxe5+
     
     
     
    At best, this move losses the Black
    player the exchange (a Rook for a
    Knight).
     
    Black has four options:
    •  5…Qe7 – blocking with the Queen
    •  5…Ne7 – blocking with King’s the
    Knight
    •  5…Be7 – blocking with the King’s
    Bishop
    •  5…Kf7 – moving the King out of
    check 
    We will now examine these four
    options in the order they are listed
    above.
     
    1.1.1
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    g6 5.Qxe5+ Qe7
     
     
     
    If Black chooses to block with the
    Queen White should take the Rook, as
    any Queen exchange favours Black.
     
    6.Qxh8
     
     
     
    This is the 3rd
     Queen move (4.Qh5,
    5.Qxe5+, 6.Qxh8) in the thematic
    move order for White, which we will
    see repeated in the other defences after
    Black plays 3…fxe5 and 4…g6.  Any
    resulting position after these two
    moves is a winning position for White. 
    White is a Rook and two Pawns up for
    the loss of a Knight. 
     
    Black cannot trap the White Queen and
    capturing the pawn on e4 with check
    allows White to capture the h7 pawn
    and create an escape route for his
    Queen.  Both of these are analysed
    further below.
     
    Analysis
    Black cannot trap the White Queen,
    because after the moves  6…Nf6 7.d3
    the White Queen’s Bishop can come to
    Bg5 allowing the White Queen to
    escape.
     
     
     Analysis
    The second option open to Black is to
    try to re-gain some material by taking
    the White pawn on e4 with check.
     
    6…Qxe4+ forces  7.Kd1 due to the
    fork on the g2 pawn.  Now, Black has
    to either move his King’s Knight
    (7…Ne7 8.Qxh7) 
     
     
     
    Or protect the Knight (7…Qe6
    8.Qxh7).
     
     
     
    Although, White has lost the ability to
    castle and is behind in development his
    material advantage should win this
    game comfortably.
     
    1.1.2
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    g6 5.Qxe5+ Ne7
     
     
     
    Black takes his King out of check by
    blocking with the Knight.
     
    However, White can go material up
    and hold a winning position.
     
    6.Qxh8
     
     
     White will be looking to bring his
    Bishop to h6 to put pressure on the f8
    Bishop or remove the pawn on h7. 
    The White Queen cannot be captured.
     
    1.1.3
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    g6 5.Qxe5+ Be7
     
     
     
    Here Black chooses to give White
    more material to go with his won
    Knight-Rook exchange.
     
    6.Qxh8
     
     
     
    And the Knight is  lost to any move,
    except a King move, because White
    can play his bishop to c4 and stop the
    King defending the Knight.
     
    6…Kf7 7.Bc4+ d5
     
     
     
    Forced, because 7…Ke8 (7…Kf8
    8.Qxg8#) 8.Qxg8+ 9.Bf8 Qf7#.
     
    8.Bxd5 Be6 (8…Ke8 9.Qxg8+) 
     
    9.Qxh7+ Kf6 10.Bxb7
     
     
    After examining all three possible
    blocking manoeuvres, to get the Black
    King out of check we can easy surmise
    that Black loses material without any
    real compensation.
     
    Black’s fourth and final option is to
    move the King out of check.
     
    1.1.4
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    g6 5.Qxe5+ Kf7
     
     
     
    Black places his King in a position
    where he has no escape square.  White
    needs to exploit this fact rather than
    snatch of the Rook on the h8.
     
    6.Bc4+ d5 7.Bxd5+ 
     
     
     
    Analysis
    Black’s moves are forced and he must
    now give up his Queen with 7…Qxd5
    8.Qxd5+ or suffer mate in 9, which
    follows the forced moves  7…Be6
    8.Qxe6+ Kg7 9.Qf7+ Kh6 10.d3+
    Qg5 11.Bxg5+ Kxg5 12.h4+ Kh5
    (12…Kh6 13.Qxf8+ Kh5 14.Qf4 Nf6
    (can be any move) 15.Qg5#) 13.Qf4
    Bb4+ 14.Ke2 Nf6  (can be any move)
    15.Qg5#
     
     
     
    From this analysis, we can see that
    Black should not block the check from
    4.Qh5+ with 4…g6.  Now we will
    examine what happens when Black moves his King out of check with
    4…Ke7.
     
    1.2
    1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+
    Ke7
     
     
     
    Analysis shows that the move 4…Ke7
    is worse for Black than 4…g6.
     
    Again, White takes the e5 pawn with
    check, forcing Black’s reply.
     
    5.Qxe5+ Kf7 6.Bc4+ d5
     
     
     
    Black is forced give up material with
    the move 6…d5 or suffers a forced
    mate, analysed below.
     
    Analysis
    Black’s other option is mate in 11 with
    the best moves played.  6…Kg6
    7.Qg5+ Kh6 8.h4 Qe7 9.d3+ g5
    10.Bd2 d5 11.hxg5+ Kg7 12.Bc3+
    Nf6 13.gxf6+ Kf7 14.Qh5+ Kg8
    15.Qxd5+ Be6 16.Qxe6+ Qxe6+
    17.Bxe6#
     
     
     
    7.Bxd5+ Kg6
    Black now has an escape square, but
    White has a winning position.
     
    8.h4
    A great move setting up many lines of
    attack: leaving Black’s position lost.
     
     
    8…h5
    Or the move 8…h6 are Black’s best
    options, giving up the Rook on a8, but
    providing escape squares for the
    struggling King.
     
    9.Bxb7
     
     
     
    Black’s best move is  9…Bd6 where
    White should play  10.Qa5 for
    maximum advantage.
     
     
     
    Analysis
    If Black does take  on b7 there is a
    forced mate in 8.
     
    9…Bxb7 10.Qf5+ Kh6 11.d4+ g5
    12.Qf7 Bb4+ 13.c3 Bxc3+ 14.bxc3
    Bxe4 15.hxg5+ Qxg5 16.Rxh5#
     
     
     
    From this chapter we can clearly see
    that Black’s immediate re-capturing of
    the White Knight, with the move
    3…fxe5, will lead to either a quick
    victory for White or a middlegame
    were White has both material and
    positional advantages.
