Villain is 27/19, 3bets 14% sb vs btn. His raise cbet oop is 15%. We are slightly deep (120 bb) but I have no idea how that changes his 3bet range. He might add more of the suited broadways into his calling range, or might 3bet them more. Important to note, that BB is a passive-ish reg, who squeezes only 1.7%, so that enables villain to call wider, so I definitely include 44 in his range as well.

Villain generally respects me, but he views me probably as a relatively aggro, bit stationy reg, but I'm not sure of this of course. 

I have two notes on him:

1. he donked flop with TPWK in a BB vs BTN situation.
2. gives up on river after a c/r bluff on flop and turn barrel. 

I'm not sure about either streets. We might be happier if we don't see a spade. It could also be better to get it in on the flop, but I elected to call. 

If I construct his range as following, then we have a plus EV shove on the turn:

[b]Board: [/b]8:spade:Q:spade:4:diamond: 2:heart:

[b]       Equity     Win     Tie[/b]

[b]MP2  [/b]  47.73%  47.73%   0.00% { 5s4s }

[b]MP3  [/b]  52.27%  52.27%   0.00% { 88, 4h4c, AsTs, JsTs, Js9s, Ts9s, As3s, As2s }

Of course if we add AQo and AQs, our equity is much worse on the turn:
