Junior5 wanted to do Bxf4 after some hours on my pentium200MMX
with an evaluation of small advantage for white(after a long time but less than
half an hour I saw that it wanted to play Bh8)

I think it is too early to resign after Bxf4(maybe Junior has a mistake in the
evaluation and black is losing but you cannot be sure about it in the game).
