Hi Madan,
TDA Rule #44: Re-Opening the Bet.
In no-limit and pot limit, an all-in wager of less than a full raise does not reopen betting for a player who has already acted and is not facing at least a full raise when the action returns to him. In limit, at least 50% of a full raise is required to re-open betting for players who have already acted. See Addendum.
Moneymaker66 has already checked and is now facing an all-in wager that is less than a full raise. So, betting is not reopened. He may call $16.12 or fold. Here, a full raise to Moneymaker66 would be equal to or greater than the size of the BB, which is $50.
Regards,
B~
