If the other hand has won 2 times in a row, right?
Then,
Any Selection's Back price is greater than 0
AND Any other Selection's consecutive wins is equal to 2
AND Trigger Expression matching_number is equal to 3
Of course set "Selections" field to "All matching selections".
Another way:
AND Any Selection's consecutive wins is equal to 2
AND Trigger Expression matching_number is equal to 1
And "selections" field set to "All but matched" (assuming it's poker and there are 4 seelections)
