Why you should shove pf:
pfr equity = 39.655 against 77+, A5s+, KJs+, A6os+, KJos+ (16% hands)
EV = 0 = 2CEM - CM - CB + B + 1
0 = 2C(.39655)(17) - C(17) - C(3) + 3 + 1
-4 = C(2*.39655*17 - 17 - 3)
-4 = C(-6.5173)
.614 = C where C = (.16/pfr) therefore -> .614 = .16/pfr -> pfr = .16/.614 -> pfr = 26.06% for this to be EV neutral so if villain's preflop raise % is > than 26.06% its +EV.
if he was min raising it would need to be
0 = 2C(.39655)(17) - C(17) - C(2) + 2 + 1
-3 = C(-5.5173)
.54 = .16/pfr - > pfr = 29.63% for this to be EV neutral so anything > 29.63% and its +EV
as played check/call the flop/turn/river
EDIT: again this is according to
