Weird and interesting spot. I think there is merit to all three lines depending on dynamics.
I think the fold is the worst option. I mean we are getting almost 4-1 to call $70 with an OP and a BDFD and BDSD. Those are insanely good odds to peel regardless of what MP does.
Shoving seems bad as all it really accomplishes is folding out the hands in MP's range that we crush. I suppose it could fold out some draws that we would like to fold out, but so could a smaller raise if he is competent. Clearly he snaps us with 2P+.
The small raise has merit too as it can let us get away if MP shoves over us. That saves us $$ in bad spots. But I just don't see it adding to our EV all that much against an unknown and it almost commits us given 40%+ of our stack will be in.
I actually like calling here due to our relative position vs MP. We can call, see what he does (he could fold you know) and then re-evaluate again. Yes it gives incredible odds to MP to come along with almost all his range but given that we may be beat in at least one spot and we likely aren't going to get monster draws to fold anyway, it protects our stack while potentially allowing us to proceed. Maybe we bink a great turn card (like 9
orT
) or a Q.
I just don't think our hand has enough current value versus an all-in and MP to be more aggro here, but hate folding too.
