I am interested to know if the above position can be held by black.  White is
short on time but can force perpetual by Qe6.  Although a rook is better then a
bishop, most of the time, should white exchange queens here?  I am only an
average player but after doing a little analysis on this position Crafty reports
the following on a fairly slow machine. (Pentium 350, 256 mb ram)

8/4b1k1/R5pp/2p1pp2/1pQq4/1P1P3P/1P3PPK/8 w - - acd 15; acn 170618898; acs 900;
ce 155; pv Kg1 Qxc4 bxc4 h5 g3 Kf7 Kg2 Bf6 Rc6 Be7 Kf3 g5;

Although white is reported to have a 1.55 advantage after Kg1 I wonder if the
position can be held by black.  I also took a look at the position with white
taking the queen and the ce still appeared about the same with black capturing
white queen with cxd4.

8/4b1k1/R5pp/2p1pp2/1p1Q4/1P1P3P/1P3PPK/8 b - - acd 17; acn 186582676; acs 902;
ce -151; pv cxd4 Kg3 Kf7 Kf3 h5 Rc6 Bf6 Rb6 Be7 g3 Bf8 h4 Be7;

Question is with queens off the board can the white rook start chopping up the
black pawns while the black bishop exists? Can someone run this on better
hardware and tkae it a bit deeper to see what falls out?

Thanks
