OK. Here are two, but they have been posted here recently. Some chess programs
go completely nuts when you give them these crazy positions:


[D]8/PPPPPpPk/3rq3/1b1r2b1/2BR1B2/3RQ3/pppppPpK/8 w

Here I don't know what is the best move.


[D]8/8/pppppppK/NBBR1NRp/nbbrqnrP/PPPPPPPk/8/Q7 w - - 0 1

Mate in one: Qh1#
