    Match Play. 5-5 to 7. How should Red play 21?

    I got pinged by XG for playing 24/23, 13/11 here.

    For money that is the correct play but at this match score this play is an error. This will be the last game of the match and Red should play the natural but more aggressive 13/11, 6/5, retaining his ace-point anchor for the time being. As it will be the last game of the match gammons and the cube won’t be relevant after White doubles next turn. Therefore the slotting play becomes correct.

    This one surprised me but I learnt something by studying the rollouts.

      So does XG make the assumption that this game will very quickly become DMP?

      This is not an opening reply that I know at this score. OTB I would play 24/23, 13/11, but I assume the answer must be either 13/11, 6/5 or 24/21.

      Asa matter of fact, I play 13/11, 6/5 after all point-making opening moves at DMP. If there is a time for pure play, it's at DMP and similar scores. If I remember correctly, GNU endorsed this move only after 64P. Perhaps now it's OK after 53P, and who knows about the next version of XP?
