Junior5.4's evaluation of the position after 14.h4 is 1.15 pawns advantage for
white.
Junior5.4 wants to play 14...Qb7 after 14.Qg4 with the idea
15.Qd3+ f5 16.exf6+  Kxf6 17.Qf3+ Nf5 18.Nh7+

Junior4.6 played 14.Qg4 in the 1000 seconds per move nunn match that is probably
not the best move.

I am not sure if the programs that play 12.Bxh7+ play it for the right
reason(14.h4) and I think that it is not so simple to win with 12.Bxh7+ even
after 14.h4
