99 donked twice.

How about just calling the flop with the intention of raising a safe turn card? Then if CO 3-bets the turn I'd let it go. If CO just calls the turn raise it seems that this play is likely to allow us to showdown for free on the river. Forgive me if this line makes no sense at all - I haven't played any limit holdem in a long time.
