Quoted from bruinfan:How about changing the game or creating handicaps?
With my family, competition nights are handicapped. All scores are converted to accommodate scoring discrepancies (JJP games vs. Williams are very different scores) and then a predetermined percentage handicap is applied. We have fun discussing what the handicap will be and why. This strategy evolves as we evolve and makes the end result scores comparable. When the others in the family win in this way, they feel like they truly won, and I don’t have to sacrifice my own games. Lots of smiles all around!
