    The dangers of a bishop at h3....

    Got back from Greece almost 2 weeks ago (in the nick of time) and am still in the obligatory back-from-abroad self-isolation, which of course means even more Internet blitz than usual. Here's an fairly entertaining queen sac that takes advantage of White's back rank weakness.

    White: Hapless victim # 1,841 Black: K. Casey


    1. d4 Nf6
    2. Nf3 d5
    3. g3 c6
    4. Bg2 Bf5
    5. O-O e6
    6. c4 Be7
    7. Qb3 Qc8
    8. Nc3 Nbd7
    9. Bf4 O-O
    10. Ne5 h6
    11. cxd5 exd5
    12. Rac1 Be6
    13. Na4 Nxe5
    14. Bxe5 Nd7
    15. Bf4 Re8
    16. Qc2 Bf6
    17. e3 Bd8
    18. Bd6 Bc7
    19. Bxc7 Qxc7
    20. Nc5 Nxc5
    21. Qxc5 Qb6
    22. b4 Rec8 (with
    23. a4 Qd8
    24. b5 b6
    25. Qa3 cxb5
    26. axb5 Qd7
    27. Qa6 Qd6
    28. e4 dxe4
    29. Bxe4 Rab8
    30. Qxa7 Qxd4
    31. Bb1 Bh3
    32. Rfd1 Qd5!!
    0-1

    Simple but effective. The threat is mate at g2. Taking the queen doesn't work, the rook check first makes no difference, and 33.f3 Qxf3 is still winning, since if 34. Qa2, Black just trades rooks and then wins with ...Qe3+. There's no defence.

    Cheers,
    Kevin

    Very striking exploitation of back rank weakness.

    GM Nunn said that humans have trouble seeing both strong retreating moves and collinear moves, his term for a piece moving on the line of an enemy attack without taking that piece. 32... Qd5 was both.
    “The history of the 20th century is full of examples of countries that set out to redistribute wealth and ended up redistributing poverty.”
    “There’s no point blaming the tragedies of socialism on the flaws or corruption of particular leaders. Any system which allows some people to exercise unbridled power over others is an open invitation to abuse, whether that system is called slavery or socialism or something else.”—Thomas Sowell
