Exactly on point, and by the way, the person was not going to win $14,000 but $11,000, this is if I am right with my calculations though.
Correct. $11,200 to be precise, as the payout was actually 1.008 not 1.01.
I have said it here before that, it would take some one with already a good experience in gambling to wager such an amount on a single bet, he or she is sure not a novice to gambling, and speaking of having respect for money, this like you said, depends on how the money was made, and I also think that emotional (could be spiritual or physical emotion) state of the person at the time of bet also has an important role to play, because I believe that even though money was made easily, its still not a reason to risk such a huge amount in a single bet, not even to win millions or dollar, but a mere $11,000, what is $11,000 compared to $1.4 million dollars?
Personally, I don't think he was very experienced, if he was he would probably know that you can get badly burned by betting on massive favorites, but I'd be guessing he had done that few times before (probably with smaller amounts), was successful and got carried away. It's way easier to stop gambling after a big loss than after a series of wins.
And I suspect he might have gambled with money that wasn't quite his or that he held for some purpose (business funds etc), for the reasons I stated in the previous post (he saw $11,000 as a reward worth the risk).
