I think is fold.
1) It's EV+ to call (or reshove) if we give him a 23,7% shoving range:

2) But, if we lower it just a little, up to 22%, it would be fold:

3) The previous assumptions are made in ChipEV, do not consider icm considerations. Therefore we have to be more cautious with a hypothetical call (or reshove).
That's why, if we do not have the certainty that BTN can be shoving here above 35-40%, we should fold.
