out of one's league
out of one's depth
caught on the hop
in too deep
buay tank
behind the eight-ball
away
have someone by the short hairs
aside
throw to the lions
tough nut to crack
have someone there
wear
bunker
zugzwang
can't do right for doing wrong
hard nut to crack
second best
not know which way to turn
out of one's element
noncoper
unsteadily
unwary
narrow-sighted
on the wrong foot
up a gum tree
tough sledding
snooker
noncommittal
with one hand tied behind one's back
fools rush in where angels fear to tread
fence-sitting
absence
over a barrel
out of one's system
draw into
drop in the bucket
careless
on the hop
dig a hole for oneself
swamp
lock into
Hollywooding
frob
know when to fold 'em
unknown quantity
in a pickle
hard put
personality clash
imprudence
stymy
stymie
down bad
centration
indirection
whistle past the graveyard
the cobbler's children are the worst shod
teachable moment
end run
puzzle
sit on one's hands
take matters into one's own hands
underthink
can of worms
halt
amicably
uncoping
the shoemaker's children go barefoot
unseemliness
whose ox is gored
out on a limb
fool
disorganized
underinstruct
box oneself into a corner
paint oneself into a corner
grapple
silver lining
where
incautiously
thwarting
bother
frustration
feel the heat
bright side
foiling
dovetailing
not be 100 percent on something
inconvenience oneself
trouble
in the lap of the gods
crosscurrent
cowardly lion
trouble oneself
sap
saphead
tomfool
muggins
box out
