Ron's chess-playing skills

As I am not a chess player, I cannot add anything substantial to that 
part of the discussion (sorry), but one thing has bugged me since my 
first reading of SS.  As Steve pointed out:
> And, as someone else pointed out, Ron had two chess pieces (Harry &
> Hermoione) that he had to guard at all cost, as well as trying to
> overpower his opponent. That substantially complicated the chess 
game.

So I wonder:
What would Ron have done had it been necessary to sacrifice Harry or 
Hermione?  I have been looking for clues in the other books as to 
Ron's charactor, and have not come to a solid conclusion.  I am 
thinking of a situation where it had to be done not only to secure a 
victory, but also to avoid imminent defeat.  No time for stalling. 
Now or never.  

Opinions?
