Thanks Sarah! The story behind the above position is this:
In the game CM 8777-Aristarch, from my Nunn1 tourney, CM here played
10.b3? - which looks to be a very dubious move. I tried several other
good CM personalities + the original King - with the same result:
9/11, 10/12 and 11/13 = 10.b3? 10.Rd7! is much better and would secure
a draw. Nice to see such improvements from CM8 to CM9.
Here the game CM 8777-Aristarch:
