If White achieves this, then he is up two tempi (Nf6–e4–f6, plus the tempo White starts the game with). In practice White is usually able to achieve this, but at some structural cost such as having to play c4, which balances out. [4] White can also force simplification with Lasker's 5.Qe2 Qe7 6.d3.
Game being played at Fairchild Air Force Base. Crud is a fast-paced game played on a snooker table (or, if unavailable, a billiards table), usually on military bases in several countries.
