AA preflop - bet size

[SomeOne]

Full Tilt No-Limit Hold'em, $0.10 BB (6 handed)

UTG ($3.70)
MP ($10)
CO ($15.10)
Button ($12.30)
SB ($1.65)
Hero ($17.65)

Preflop: Hero is BB with A, A.
UTG raises to $0.35, CO calls $0.35, 1 fold, SB raises to $1.65 (All-In), Hero ???


UTG raiser and SB reraiser are both donks, but CO is solid player.


How much should i bet here, or do i just shove to isolate against SB?

[no eff eks]

I like a 4-bet to $4.

Everything, that you do, looks strong here (exept folding^^). So your hand is already defined => give nobody the right implied odds, to call.
