Sorry if I'm interjecting and grabbing the wrong end of
the stick here but surely something is obviously missing
in this analysis. The chances of 2 doves surviving long
enough to meet each other in an environment otherwise
infested with hawks must be very low or require some
additional assumptions about the environment such as
that there are places doves can go to meet that hawks 
can't easily get too.

I'm sceptical of this but I could be wrong and would
be interested in the research.

I though Tit for Tat as per Axelrod's studies and others
latter only applied in two party games with repetition.

A getting vengence on C for tats by B isn't tit for tat in
the common understanding of tit for tat is it?
