Here is the row with analysis:

[D]1r1qrk2/1pp2p2/p1n1b2p/6p1/3P4/P2BPNP1/2Q2PP1/R1R3K1 w - - acd 16; acn
546132125; acs 1000; ce 116; pv Be4 Bd5 Qc5+ Ne7 Bxd5 Qxd5 Qxc7 Rbc8 Qb6 Kg7
Rxc8 Nxc8 Qc7 Nd6 Rc1 Rc8;

I have seen the same thing happen many times.  In fact, I have several wins
against Arasan  because of its resign bug.  I have had Arasan resign when I was
down as much as a full piece (on several occasions) for no apparent reason.
Being an unspeakable cad, I accept.
;-)

I have reported the bug to Jon Dart, who has also heard of reports of it from
others.
