Lavieri's Promoter has negative value. You'd like to get rid of it, but cannot. The only way to eliminate Promoter is enemy's capturing your Promoter, and he is unlikely to do so. One can think up extremities where capturing the Promoter might occur, a final checkmate in view, but that would be overcome only if you come up with some better move than he/she has planned. Promoter of course lets any captured piece be promotee if opposite piece lands adjacent. So your strategy generally is to get Promoter out of middle of the board and behind lines, where P. is even less likely to be captured. You're stuck with it the duration of every game played so far. Negative value.
