| This game shows the strength of Saginaw's Dave Hahn,
a prize-winner in the Expert Section in the Chicago Cup tournament over
Memorial day weekend. Black prepares the fianchetto of his king-bishop
by g6, but never completes it. Instead, he trades off the defender of those
weakened squares. Hahn delivers the appropriate punishment by a vicious
mating attack on the dark squares. — Bob Ciaffone. |

Notes by David Hahn
1.c4 Nf6 2.Nc3 g6 3.e4 3...e5 4.Nf3 Nc6?!
| Better is 4...d6 on this move or the next. |
| Bad; White has only a slight advantage after 6...Bg7. Trading dark-squared
bishops will be fatal. |
| Black foolishly kicks the queen where it wants to go. |
| Thwarting the Qg5+ trade idea and zeroing in on the dark squares. |
| Oops! Black now has to make a very ugly move, since his king-rook is
attacked. Castling, of course, is impossible due to the Nf6 threat. |
| After 14...Rf8 Black would have a terrible position, but this is even
worse. |
| Materially, Black is not so badly off, with a rook and knight for the
queen, but look at the way his rooks are posted. |
| Black misses the threat of Qd2+ winning the Rh6. |
| Once White's rook and bishop enter the game, Black will be pulverized. |
| A temporary piece sacrifice exposes the Black king to deadly force. |
| Mate. Some people seem unaware that a player can prevent this
fate by resigning. |
