Better to 4bet-induce imo. Would make it like 1,52ish. To give him a chance to think you still could be bluffing and that he would have FE if he shoves. To let him spazz.
Also think you are more likely to get his whole stack if he has the valuehands JJ+ and Ak if you 4bet-induce instead of shoveing.
Hmm maybe not more likely. I guess it won't make that big of a difference, but if you take the spazz in consideration 4bet small is better imo.
