What would you play, please explain?

I'd play B/24 13/7. You're already behind anyway. Your barpoint is really important here, trying to block White's back man. The other 6s don't offer much anyway.

Time to get real. Theres a saying thats usual true but not always - "do not slot while split". Here that means if your opponent does not hit the slot he will have the ability to attack either of your 2 blots on her side of the board.

So what to do. The 1 is easy, then the 6. If we reject 13/7 as explained above, we come down to 2 moves 20/14 or 11/5. AFter 11/5 white escapes with 65, 64. Hits and makes a point with 11, 22, 21, 52, 62, 44. Then there are the hit loose rolls with 1's, 2's, 5's and 6's. If this sounds like a good idea to you - then we need to play. OTB I would just say I would rather be hit on the 14 point than in my opponents inner board as when I'm hit in her inner board then she will either have made a point or hit loose trying to make another point - and I want to avoid that. So 20/14 would be my gut play.
