Hiarcs 7.32 finds b4 at depth 9/27 after 19 seconds on my Pentium II 350 MHz
with an eval of +3.78.  At depth 10/30 after 75 seconds, the eval goes up to
+4.03.  This is its best move.
My other old Chessbase programs do not find b4 after 3 minutes of analysis each:
 Fritz 5.32, Comet B02, Crafty 16.6, and Doctor 3.0 prefer rook moves which they
evaluate as winning for White with a +2.xx advantage.
