No problem my friend. The D-Pad ( directional buttons ) on the left of your controller. Quick rundown -
: left - classic play = excellent for breaking the line
: right - pivot = fly half holds on to ball while players make snaking runs round, useful for in and around the 22, not for distance gain
:up - dummy switches = the fly half fakes passes to fool defence.
: down - in the pocket = the fly half sits back to give more room for a kick. useful in either 22 to kick clear, or kick for a drop goal.
If you can't understand me, just let me know and I'll try to make it clearer.
