The idea is that you need krpkr, krnkr, krbkr, krrkr, and kqrkr, in addition to krpkr. if you don't get them all, it will appear that an underpromotion will avoid the mate, so just getting kqrkr won't solve the problem. >A little example : > >[Event ""] >[Site ""] >[Date "1999.08.12"] >[Round "?"] >[White "Bringer 1.5"] >[Black "CM 6k 1.03"] >[Result "1/2-1/2"] > >1. d4 Nf6 >2. c4 e6 >3.
