Thanks for the responses. I saw all the options but chose the blitz rather than the naked ace point. Blitzing does win more gammons but 20/15(2) 6/1*(2) wins more games without losing the gammons that 20/10(2) does. 20/15(2) 6/1*(2) might even be the DMP play.
Mike Taper asked for the game sequence up to this point; I don't have it on me but I'll try to remember to dig it up and post it later.
