    Given a polynomial x10+a9x9+…+a1x+1\mathrm{x}_{10} + \mathrm{a}_{9}\mathrm{x}^{9} + \ldots +\mathrm{a}_{1}\mathrm{x} + 1 . Two players alternately choose one of the coefficients a1\mathrm{a}_{1} to a9\mathrm{a}_{9} (which has not been chosen before) and assign a real value to it. The first player wins iff the resulting polynomial has no real roots. Who wins?
