P = 1, N = 3, (WA) = 3.5, B = 5, (BW) = 7.5, R = 7.5, Q = 13.5 is just a guess at middle game piece values under Alice Chess rules. Recently I thought about adding some Chu Shogi pieces to this variant. Multiplying the numbers for N, B, R by 1.08 brings us very close to the Zillions estimates that Antoine Fourrière listed in this article. Zillions values a Queen in Alice Chess as slightly lower than the total of a Bishop and a Rook (just as it does for FIDE Chess). The relatively low value of a Knight is probably because it is "Alice colorbound" (light squares on one board and dark squares on the other board).
A simple Alice Chess endgame with all chessmen on the first board: WHITE: King (f1), Pawn (a6) BLACK: King (a8).
After 1. a6-A7 a8-B7 2. A7-a8 and promotes. The Black King was never on the right board to make a capture. Looks like a Pawn may be worth fifty percent more in the endgame. Variant Chess: Volume 6, Issue 42 is available on the web, with three games on pp 20-21 and the article "Paradoxical Endings in Alice Chess" on pp 28-29.
