The finish of the game involved a very forcing sequence, so it is not surprising that computers chose these moves. It is intersting that in the starting position the computers analysis starts with f5. This move must be mostly for the purpose of preventing Be4, but Qd5 does this as well, and with other added benefits. The computer does not see at this point that accepting the exchange sac is unsound. > >[d]r1bq1rk1/pp3ppp/4p3/8/1bNP4/3B4/PP2KPPP/2RQ3R b - - acd 15; acn 1002531606; >acs 36008; ce 62; pv f5 Qa4 a5 a3 Be7 Ne5 Qb6 Rc2 Rd8 f4 Qxd4 Qxd4 Rxd4 Rhc1 Rd8 >Rc7; > >It is interesting that even in the last position, the chess program does not see >the problem.
