Geoffrey Coleman Vienna Hara-Kiri 5.g4

Playing the final round usually means that you know where you stand where it comes to winning any prizes. A few people who have won most of their games are in contention. The rest are not. In correspondence chess, the rounds have multiple games. In postal chess, rounds took years to play. By the time I got to the 1989 Golden Squires Postal Finals, I knew that my opponents and I: (1) had already complete a dozen games; (2) would play for years without quitting; (3) had knocked off a much of our competition; and (4) we were probably out of the running for the few prizes at the top.

My first game with Geoffrey Coleman was in the section USCF 89SF7. Here we contested a sharp Blackmar-Diemer Gambit Vienna Hara-Kiri 5.g4 Bg6 6.h4 variation, instead of Tartakower's 6.g5 Nd5 7.Nxe4. Probably we were worn out, and being rated close to each other, agreed to a last round draw after the middlegame. My second game with Coleman was played at the same time and is scheduled to be posted on my blog in 10 days.

Christoph Scheerer wrote of this line in his excellent book: "More ambitious but also more risky is the Hara-Kiri Gambit with 5.g4. Sometimes White may even be a pawn up for a change, but in the long run Black will have the superior structure. On the other hand, the position is at least unbalanced, which may allow White to outplay his opponent."
