Other things are not equal: it already is a draw per 5.2.2.
There can be no success as it already is a draw.
Besides it is not my rule, it is Capablanca's.
Moreover it is a position of 3 men and all positions of 7 men or less are strongly solved.
The rule is: 'Other things being equal, any material gain, no matter how small, means success'.
Where do you mention further calculation or evaluation?
Any remote chance of answering my original question, "What other things are not equal here, pray?"
