Rules Update and Measurements

[RMS652]

Good day,

I recently noticed that there has been some changes in the quantum chess game on steam which had previously advertised the rules on which we play here. Instead of a double move, it is now a split move (you pick two of your possible locations), as well as later on selecting both possibilities and merge them at a square where they both reach (merging the superposition states into one where any of those could have happened).
Pawns seem to be now unable to perform quantum moves as well.

Regardless of the rules changing, I was wondering the following:
Say I tried this quantum move which leaves the piece almost empty (just 20%), but I am exercising a check, how can I try to increase the likelihood of my piece being there, as I see when I play that there are moves which cause the probability of a piece to increase, but I am unsure if there are any particular things I could try to make this happen. Or is just a matter as leaving the piece there and hoping I get those 20% odds.
