WHen I let Baron search after 4..Kxb7 it returns a major score for white at
first, but at depth 25 the score begins to drop:

depth 26 (1195 secs, score 262):
5.Kd6 Bb1 6.g7 Ba2 7.Kd7 Kb6 18.Ke7 Kc7

The rest of the PV is not available from the hashtable.
7.Kd7 instead of 7.Ke7 is a clear sign of troubles - pushing the repetition over
the horizon...
It might require a lot of thinking and a lot more depth before Baron shows a
draw score.
