Hi!
Today Hossa lost a game in the following position because he didn't take care
enough of his king:
4r1k1/1Bpq1ppp/1bNp4/P3p3/3PPnb1/2P5/2Q2PPP/4RRK1 b
Hossa had white against "blunite" and the last move was a5? Black won with Bf3!!
How long does your program take to see that Bf3!! is winning (or does it find an
even better move?)? Here is the analysis of Hossa:
