SWINDLE MODE

Messrs. Jimmy Walker and Harald Faber have perhaps forgotten about "swindle
mode".  I believe this was first introduced by Bob Hyatt in Crafty.

Hiarcs7.32 knows that it is a draw, but White is a pawn up and what's wrong with
trying to win this?  So it makes the  best move under the circumstances hoping
that Black will blunder.

Take note that after white moves here, Hiarcs7.32 will immediately show an
evaluation of draw for Black.  But after black moves white will again show an
evaluation of +1 and try to win.

In short, Mr. Ripple, hiarcs7.32 has accessed the 5-man Tablebases, notes that
it is a draw, but still tries to win it.

I may be mistaken, but I think I read about this from Steve Lopez, either one of
his T-Notes or a posting here.
