In Response To: Ten Things I Hate About the BG Experience (Stick)

From one of my recent money round matches where if I win I get over 2k, I lose I hover around the $0 mark. This is an example of the kind of play I hate beating me. (these are plays I had from pictures, imagine if the match was recorded)

The score (after 0 games) is: user 2, gnubg 3 (match to 11 points)

Move number 3: user on roll, cube decision?

He cubed, I take, not really a bad cube but one I prefer not to throw if I was in his shoes, the take is such a snore I'd rather try to tick off a small improvement and give my opponent a real decision. Good thing he cubed though because...

How can you make that play? Puke - I'm impressed it's only a .05 error, perhaps it would roll out larger but I'm not wasting the time.

I double here and he takes? Of course he takes...then he rolls 66, then he gets in a recube that's a monster take before I lose the game. Instead of winning 1 as standard outcome, I lose 4.

He cubed me here ... hmm... yea.

These are things you'll see in any given weekend at the ABT and I was still able to get to DMP before losing this match. I hope it provided a bit of entertainment for you, I know it didn't for me at the time.
