One last thing...
No way in the world was Martin expecting Nc6. He was expecting O-O-O.
I bet we threw him for a loop.
Still, I envy him because he has a nice position to work from.
We struggle while he just wakes up everyday, and casually decides what he wants to do.
Hoping for complacency on his part.
(but I really think he's going to play Nxc6+)
White playing Knight to the Rank 5…
… O-O-O
Anyway, it get heavier and heavier, but no immediate jeopardy along this line. It's just very tight and we may not be able to defend everything.
And I've now listed the 3 possible, and most likely lines: the Nxc6 line, the Rd1 line, and the Nb5 line.
That's about it… so we wait to see what Martin plays.

P.S. I'm brand new at posting these Diagrams with Moves, so I have a lot to learn on them.
