playing a 100/43 (lol) your gonna have no fold equity pretty much ever so just wait for tp and stack him

"playing a 100/43 (lol) your gonna have no fold equity pretty much ever so just wait for tp and stack him"

If i have no fold equity is he calling with worse hands? I feel i should be shoving unless he is only doing this with a pair. i mean if he calls with 79 and the like i clearly should be shoving shouldnt i?

also i know top pair will stack him np i just want to know if this specific situation is a +ev preflop move as well as what i should do on the flop
