stick to one's guns

choke off

cut corners

the old school

in over one's head

stomach for

under arms

face the music

call A's bluff

rise to the occasion

from strength

straight face

strike a balance

freeze out

turn green

guinea pig

get a move on

strut one's stuff

a good bet

hang about

stumble upon

tie the knot

horn in

take A by storm

break ranks

swarm with

strut one's stuff

put one's foot down

in the driver's seat

swear by

beyond one's wildest dreams

like clockwork

in the know

blow up in A's face

take a bow

by inches

air out

take A by storm

well out of

on a shoestring
