At a camp I was at recently they taught...
Step up (towards home) with the foot closest to the ball,
Then pivot so you have "belly to the ball"
Follow through with the other actions described by Tee.
At first I didn't like this stepping away from the play at 2nd. And making that step with the foot closest to the ball seemed counter intuitive... now I've got it. They didn't explain it well at the camp, or I missed it.
Yes, the "step-up" is AWAY from the initial play at 2nd but it is TOWARDS the proper and final position (to get the good angle) at 1st.
In the play first described F6-F4-F3, BU at position B, the first step towards home with the right foot is away, distance-wise, from 2nd. But the subsequent pivot towards the ball on that right foot gains you the needed angle for the play at 2nd. And the initial step also got you closer to the half-way point of the 1st baseline (end of the 45 foot line) for the proper angle to make the call at 1st.
Alone, the initial step seems counter-intuitive. In the big picture - smart move!
