Yes it should be bad Jim.

Why not try:
Code:

if ((nScore=Quiesce(nAlpha, nBeta, pvLine) < nAlpha - nMargin[nDepth])
         return nScore;



Note i didn't figure out how this works out at depth 0 for you.

Also maybe add to the margin pvnode*128 and drop the pvnode condition for the betapruning.
