| agb2002: White can take the knight closer to the black king with 30.Nf5: A) 30... gxf5 31.Rg3+ Ng7 (31... Kh8 32.Qf6+ Ng7 33.Qxg7#) 32.Qf6 and mate next. B) 30... Ree8 31.Nh6+ Kh8 (31... Kg7 32.Qf6+ Kxh6 33.Rh3#) 32.Nxf7+ Rxf7 (32... Kg8 33.Nh6+ Kh8 34.Qxf8+ Rxf8 35.Rxf8#) 33.Qxf7 wins ... |

Sep-21-23 C Liang vs Z Zhang, 2001
| |
| agb2002: Black is two pawns down.
White threatens Bxf8 and Qxb5.
The white bishop is defenseless. This suggests 32... Nd3+ 33.Rxd3 Qa1+: A) 34.Kc2 Rf2+ 35.Rd2 (35.Kb3 Q(R)xb2#) 35... Rxd2+ 36.Kxd2 Qxa1 wins an exchange with more or less balanced material but the white king is more exposed. |

| agb2002: How annoying: I was so focused on the black king that overlooked the simple 24.Ne6+ f6 25.Qxc5. |

Sep-20-23 A Antunes vs A Bejaoui, 1997
| |
| agb2002: White is one pawn down.
The rook on b8 and the black knight are defenseless. This suggests 19.Nc6, with the double threat Nxb8 and Bxg7: A) 19... Bxc3 20.Nxe7+ Kg7(h8) 21.Qxc3+ and 22.Qcx 5 wins a piece. B) 19... Bf5 20.Nxe7+ (20.Bxg7 Kxg7 21.Qxc5 Bxb1 22.Nxb8 Bf5) 20... Kh8 ... |

Sep-19-23 A Needleman vs A Cordero, 2003
| |
| agb2002: White has two extra pawns.
The black queen is defenseless. Hence, 44.Rd8+ Kxd8 (44... Ke7 45.Bg5+ f6 46.Bxf6+ Kf7 47.Qxe4 is even worse) 45.Bg5+ Be7 46.Bxe7+ Kxe7 47.Qxe4 wins decisive material. The alternative 44.Bg5 Qa8 (44... Qxg4 45.Rd8#) 45.Rd8+ (45.Qd4 is interesting) 45... ... |

Sep-18-23 A Kovalev vs A Ushenina, 2003

| agb2002: Black threatens g4.
White can attack the black king with several pieces starting with 15.Rxe6+: A) 15... fxe6 16.Qxe6+ Kf8 17.Qxh6+
A.1) 17... Rg7 18.Nxg5 Re8 (due to Ne6+) 19.Ne6+ Rxe6 (19... Kf7 20.Nxc7 Re1+ 21.Bf1) 20.Qxe6 Bxh2+ 21.Kf1 Re7 (21... Rf7 22.Bh6+ Kg8 23.Qg6+ Kh8 ... |

Sep-17-23 M Ragger vs M Leon Hoyos, 2008
| |
| agb2002: White has an extra pawn.
The black queen protects the bishop and the rook on e2. This suggests 30.Qxe2 Qxe2 31.Bxd4+: A) 31... Kg8 32.Rg7+ Kf8 (32... Kh8 33.Re7+ wins a piece) 33.Rcc7 A.1) 33... Qd1+ 34.Kh2 Re1 (34... Qxd4 35.Rcf7#) 35.Bc5+ wins (35... Re7 36.Rgxe7; 35... Ke8 ... |

| agb2002: White is one pawn down.
Black threatens Qxe2.
The knight on e7 protects c6 and g6. This and the threat suggest 28.Rxc6 (28.Kf1 Nxd4 looks bad for White) 28... Nxc6 (28... Qxe2 29.Qxe7) 29.Nf4: A) 29... Qxd4 30.Nxg6 fxg6 31.Qxg6+ Kh8 32.Qh7#. B) 29... Qe1+ 30.Kh2 Qxf2 31.Ngxe6 fxe6 |
