The mental adjustment to the value of one’s hand in the light of the previous bidding. For example, a holding of K-x is likely to improve in value if one’s right hand opponent bids the suit but decline in value if one’s left-hand opponent bids it.
Even a holding of small cards can improve (or decline) in value as the bidding progresses. For example, if you have 8-5-2 in a suit and RHO bids it, you will treat this as a poor holding as any honours partner has in the suit will be under the bid.
However, if LHO supports the suit strongly, you will place partner with a shortage and adjust upwards, knowing you have no wasted values in the suit.
