I'd shove here, any decent sized raise commits you & 88 is not a hand which wants to encourage seeing a flop or a hand you want to go n go with or a hand that wants to invite someone else in.
I guess 3-betting to 2300 (~3x) has the advantage that you can fold if SB & BB both jam but that's very very unlikely & I don't see many other advantages.
Flat calling is better than folding but it's not going to be particularly easy to play a flop (basically your committed on most boards & he plays pretty perfectly) & you dont want to encourage the blinds in.
