4 positions from Fidelity Phantom - MM II
 

Hallo,
I am doing a match between these 2 machines (1min/move). During the 17th game, I have taken 4 positions which can be used as tests for your engine (or for you).
The solutions are given at the end. Note that "easy" or "hard" are just relative words ;) Note also that the Phantom and the MM II have not seen the best moves, except the last. Note also that "winning" is also a relative word :p

• ; game 17 Phantom - MMII black wins (hard)
• ; game 17 Phantom - MMII white is lost even with their best move (hard)
  
• ; game 17 Phantom - MMII white wins (hard)
• ; game 17 Phantom - MMII white wins (easy)

Solutions :

• 1/ winning move 25...Nh4
• 2/ even the best move 32.... Bc1 (or Be3) is loosing, for instance look at the Fruit 2.1 analyses lines:
• 14/47 00:37 39 267 399 1 058 211 -2,48 1.Bc1 Rxa2 2.Qxa2 Rxe5 3.Qg8+ Kb7 4.Qf7+ Bc7 5.Rg1 Rh5 6.a5 a6 7.b5 Rxb5 8.Be3 Rb2 9.Bf2
• 14/48 00:52 56 288 295 1 072 223 -2,26 1.Be3 Rxa2 2.Qxa2 Bxe3 3.h3 Qxg2+ 4.Qxg2 Nxg2 5.Kxg2 Bd2 6.Rf1 Bxc3 7.Rf8+ Kb7 8.Rf7+ Kb6 9.Rxg7 Bxb4 10.Rxh7 Rxe5 11.Rd7
• 15/51 02:11 139 916 580 1 062 940 -2,25 1.Be3 Rxa2 2.Qxa2 Bxe3 3.h3 Qxg2+ 4.Qxg2 Nxg2 5.Re2 Nf4 6.Rxe3 Nd5 7.Rf3 Rxe5 8.Kg2 Re7 9.Kg3 Kb7 10.b5
• 3/ after 32...Rg6?? winning move 33. Rxf2
• 4/ after 43...a6?? winning move 44. b5

Hope you like them
