2nd is better then nothing
Swog, you were right the only way for you to win was to DD for less ($1,100). And you were also right that by doing so you could have gone from 2nd to 5th place $2,500, a $7,500 loss.
BR1 Macway had 1st if the dealer made a hand (which they did).
BR3 Shin had 1st with a dealers bust.
BR2 had 2nd no matter what.
With the chance of you busting I think I would have done the same as you.
However I think they're were several bad plays made or (not played) on the last hand.
BR5 Evelynn should have DD for less if she wanted any chance of winning. I would have keep back $250 to assure 5th place. She ended up in 4th place for $3,500.
BR1 Macway made a horrible bet only betting $500. Both BR2 (you) and BR3 could catch him with that bet. He needed to play $1,600, this would have given him both high and low for the win and enough to cover your DD had you (BR2) gotten a DD as well. Only a swing would have beaten him. As it turned out he won anyway, congrat's on the $20,000.
BR4 Ryan should have DD in their position since they're were three players in front of her, for any chance of her winning. She moved up to third and collected $6,000.
BR3 Shin was the only player to DD on the last hand (he had an 8 & 2) and caught a 3. He dropped from BR3 ($6,000) to BR5 ($2,500).
So should you have DD? Who knows, look at the results from below.
BR1 - WRONG thing and WINS
BR3 - RIGHT thing and drops down 2 places (-$3,500)
BR4 - WRONG thing and moves up one place (+$2,500)
BR5 - WRONG thing and moves up one place (+1,000)
I guess in gambling "Wrongs can make a Right"....LOL!
