AK value call then squeezed vs 2 TAGs

CO is a std TAG who is running a mostly unimaginative 18/14. Steals 30%.
SB is an even bigger Tagnit running 16/13 over 150 hands. His A2S is 20% so I doubt he is 3betting too light here. My notes do not mention 3betting light.
I'm running my std 21/17ish. Haven't been out of line but my A2S is 35% & SB might see a good opp to squeeze here.
First, what do you think of my play just calling the CO TAG who will fold to most 3bets & probably only call with better hands? I'm sure the common answer will be to 3bet CO with a wider range, but the opportunity just hasn't presented itself at this table & I don't know his opinion on my usual 3betting style. Probably thinks I 3bet a little light, but not crazy light.
Second, where do you go once the Nitty TAG 3bets and I'm sitting on AK IP? Is this a 4bet>fold>call?

Preflop: Hero is Button with A, K.
2 folds, CO raises to $3.8, Hero calls $3.80, SB raises to $14.2, 1 fold, CO folds, Hero calls $10.40.

Flop: ($33.20) T, 6, T (2 players)
SB bets $22, Hero folds.

Final Pot: $33.20

Any more than 100bb deep I don't like this play. When the SB squeezes I'm tempted to make it $35/call.

I like your preflop play much better with AA than AK, but even then I don't think it's necessary with nits in the blinds. Just 3-bet to about $13 and stack off.
