During the match, I had the feeling that the Phantom was stronger than MM II. Some of the games were very pleasant, as can be seen below (game 17). Some of the games were just a succession of blunders from both sides. An other interesting position is this one :

 

6k1/p2b2p1/p1pb1p1p/Pr1p4/R2P3P/3NP3/5PPN/6K1 b - - 7 32 ; game 18 MMII-Phantom

 

After 31. Ra4 ?? there are several winning moves for blacks. The Phantom found one of the winning move. Could you find it?
