Isn't the Queen is either alone or with a small contingent of "Elite Bodyguard"? I don't think a lone woman or 20-30 elite soldiers will be able to take on even 1000 peasants with pitchforks (the size of a regiment) I highly doubt anyone will go to war with. You can just attack them from the side with your Infantry Regiment (at least Men-at-arms) at G4 that are covered by F4 and while the Queen's guard are distracted you can rush and potentially capture her with the Infantry at H2 or send in the Cavalry at G1 if the Elite Guard aren't equipped with spears. Having no troops close by Black can only hope to counter F4 with the Infantry on E6 and rush the Infantry at H7 to H4 and hope they are fast enough to assist the Queen's guard and escort the Queen back. Anything more would expose the flank too much and make it vulnerable to a counter attack. In other words this tactic is a complete failure as it leaves White at a great advantage and potentially destroys a third of Black's infantry. But the bigger question is what is the Queen of all people doing on the battlefield.
