$10+.75 HU DS - min4bet with 50bb effective

My Reads/thought Process for this hand:
-His stats are very weak-tight, like 50/10, really more of a caller than a raiser. -I'm certain he's slightly tilting despite the match having gone on for under 50 hands. I've basically ran good and pulled off a pair of good mediumsized bluffs, just running him over before herocalling with top pair when he instapotted rivering a runner runner flush draw. That hand was maybe 5-6 before this one, and the stacks have basically evened up.
-I've 3bet multiple times in the match mostly from getting good cards. This is like my 3rd time with TT.
-I think he's less likely to have super premium hands like QQ+,AK because he minraised pf. This is an incomplete read / obv uncomfirmed, but it was what I felt was true at the time. All of his "honest" pf raises have been mid-high PPs, suited broadways (at least the ones he's shown down), and the minraises have been weird marginal connector, broadway-rag type hands. Of course, when he min-4bets, I have no idea what to think.

I'm sad to say I have no clue what is optimal here.

On one hand:
I think against his range, a shove here could be bad because I believe I have a massive edge against him postflop and to take a marginal flip against some spastic-played PP, AJ+ range where he might be weighted towards KK/AA if I can give him credit for that.

Yet:
That same 22+,AJ+ range I have 60% equity against. And it's entirely possible his range is wider than this. As mentioned above with the tilting, it's entirely plausible he cracked a few hands ago and wants to start shoving 50bb stacks around with KTo.
