My Junior5.9 simply captured by Bxd5(evaluation 0.06 pawns for black at depth 15
and 0.16 pawns for black at depth 16)

I guess that Junior6 can also capture at d5(maybe the time control of the game
was too fast)
It wanted to play Rxc4 at depth 9 but changed it mind at depth 12 and prefered
the move Bxd5.

If I give it 81 minutes per game on pentium200 it also plays Bxd5 at depth 13
and it never considers Nf5.
Only at fast time control(when I give it 30 minutes per game on p200) it wants
to play Nf5 at depth 11 and does not change its mind at depth 12).

I think that Junior had not enough time and at longer time control mchess is not
going to win the same opening.

I guess that from Junior's point of view it lost because of a tactical mistake
Nf5(Junior simply did not calculate deep enough).
