Merc Chess

In days of olde when knights were bolde
and battled ‘pon fields of valor,
twer also knights rouge who’s bane swords were sold
causing stead men to lighten in pallor.

A game then arose, with its colors opposed
to pay homage to noble combatants,
which taught strategy but taught naught, s'tragedly,
of deeds lacking nobilital patents.

Without chivalry and denied heraldry
men marched oft quite unsung to their slaughter,
should stratagems taught belie tactics as fought,
just ‘cause some armsmen’d not done as they’d aught'r?

Victors write history, but no royal decree
saving face can now force us to tarry.
Let us put paid to lore'n, rightly settle the score.
Reenlist the Chess mercenary.

The only variation from real Chess rules is moving a mercenary chess piece (red), after every ordinary move. [link]
(not to imply that your move would not be spectacular or anything)

Once you have moved a merc piece it remains employed by you until control is relinquished by moving a different merc piece.
An opponent can not move a merc in your employ.
A merc pawn can move one square in any lateral direction, and only attack on the diagonal.
A merc pawn can not reclaim your Queen.
