Watcom-Patzer on K6-233 DOS Window under WinNT 4.0 (16 MB Hash ?)

It.5  0:02  -M7   Bxa8
       0:03  3.35  Ne5
It.6  0:06  3.70  g4
It.7  0:22  3.62  g4
It.8  2:01  3.12  b6
It.9  3:28  3.46  g4

That is the version with lazy evaluation window = 130 ( = two pawns ).
Djordje, if you want to reproduce it, set the variable "poswin" to 130.

The previous version that had a lazy eval window of 96 (1.5 pawns)
needs very long to see that Bxa8 looses. So a minor change produces
very different results.

When Patzer sees at iteration 5 that after Bxa8 it gets mated it removes
this move from the move list. That helps in this position but is it
correct?

I did not have the time to investigate if is really a mate in 7 after
Bxa8.
