first off folding is out of the question.

you say SB has toned it down since 4-handed play started. has he repopped you at any point since then? if he hasn't, then raising and folding isn't terrible. i'd make it 2.5 in this case, but you do need to fold if he shoves.

shoving itself isn't bad, but if SB's reshoving range is very small then simply raise/fold is better. for a good player i'd imagine he'd reshove a wide variety, so i would just shove. since you said SB has toned it down though, i might consider raising and folding to a shove from SB. it really just depends on what you estimate he resteal range as, or whether you think he's aware of the $ bubble
