In my opinion you have several possibilitiesmadaxeman wrote: How would a "let's agree a draw as you clearly would be mad to come out and attack my mounted army on this plain, and I'm not assaulting that defensive position in the corner surrounded by terrain that you've dug yourself into" play out?
1] Except a bottom score for the round (Fine by everybody else)
2] Come up with a cunning plan to tempt the other player to make a mistake by sacrificing not to much but just enough (Exciting for both of you)
3] Don't bring such a monochrome one-dimensional army in the first place (Maybe only a little twist that turns an OK army into a great army)
