US Championship 1973 — El Paso

1973 · El Paso
Lubomir Kavalek and John Grefe shared the title on 9½/12; no playoff was held.

Surviving score versions

All 78 games are represented. The retained Gilden–Kavalek score ends at 69...Rf4+ and Kavalek–Bisguier at 59...Ke5, as in Chess Life & Review (1973); the 1975 annotated tournament book continues them through 71...Rf3+ and 60.Kf6. These two scores are shorter than the later book’s versions. Published versions also differ in the opening move order of Grefe–Browne; the retained version follows the annotated book. These score variations do not alter the official results.
