Pocket JJ, Is A on the turn a check behind

So I check behind and check/call a river bet. My thinking is most hands I will beat will fold (except draws), and most hands I am losing to will cost me 2-3 more bets.

If you bet the turn, you should fold to a checkraise.

Occasionally you'll get checkraise-bluffed or checkraise-semibluffed here, but keep in mind that Villain is checkraising a preflop 3-bettor with an ace on the board.
