GO-6-MOKU with restricted dagger

Rules of 9x9 Go, except that there is no passing and the winner is
whoever gets a 6-in-a-row. Suicide is illegal, except that a 6-row
may be completed in an otherwise liberty-less position. No swap.

Neither dagger move may be used to capture, and they must finish
in different groups.
