Case contract

Input [game(D/H/S/C/G), trumps_held, hand, schneider, schwarz]. Base D9 H10 S11 C12 G24. Matadors count the unbroken run from CJ down the trump sequence (CJ SJ HJ DJ then A T K Q 9 8 7 of the suit; grand only jacks), either held ("with") or missing ("without"). Multiplier = matadors + 1 (game) + hand + schneider (implied by schwarz) + schwarz. Return base * multiplier.
