It has happened that Phalanx scores 6-2 against another engine at blitz level and than loose the rest of the games. When you take a look at the pgn-file you see that Phalanx looses in <=40 moves. Sometime <=20 (!!). Because of this I only play Phalanx with /mg=1 against other machines. So I get very good results for Phalanx and I think it is very strong. Could you please test it with the option /mg=1 and post or email me your experiences ?
