I think I know at least one answer...how about the rest of the Herd?

Although XG says it is a small error to double, this seems to me to be a very good practical double. For one thing, passing would be a HUGE error, but some players will pass this one.  I'd gladly eat the .014 theoretical equity loss in exchange for a pass here.  For another, when you hold a close decision you can make the same mistake over and over again; you can only make an wrong double error once.  So if you're trying to lower your overall PR, doubling when you're not quite sure you're at the DP can be effective.

So, good double.  MASSIVE error to pass and I'm glad the herd was able to make the correct decision. (I was away over the weekend and missed the action, so I can't take any credit for this.)
