If we were behind in the match, I'd hit loose with 15/9 6/3*.  At 2-0 I'm more cautious, so I'm going to vote for playing it safe with 15/6.  Yes, this makes two ugly candlesticks, but I don't like the look of his zone so I don't want to be hit. I wish there was a more flexible play, but  I'm not seeing it.

Actually, I think 15/9 6/3* has much to recommend it - we're probably going  to leave a blot anyway before long, and doing it now with his poor board and blot on the 5 makes some sense.  I just don't have the cojones to vote for it, but I could have my courage bolstered by the right argument.  Anyone?
