Hmm, the result is totally different when I show only one variation at a time:

Fritz 7 - Eassa,R
3qr3/3bppbk/3p2p1/p1rN2Bn/PpnNP2P/1B3P2/1PP2Q2/1K1R3R w - - 0 1

  ±  (0.72)   Depth: 12/38   00:02:06  67263kN

I did not realize that showing multiple lines simultaneously would cause the
thinking to change so dramatically.
