Polish Defense after Nf3 :: 1.Nf3 b5?

.


.
90 Games w/ 2 1 Time control
White wins 44 (49%) Draws 25 (29%) Black wins 20 (22%)

Again I ran a tournament because I was a bit stumped in a couple of 1 min matches on Chess.com. Although I held off in a few games, the guy still got me a couple of times. The tournament was run so I can see the good defense. I was mistakingly following up b5 w/ e4 and that usually left my pawn structure messed up or some piece running around the board all crazy like. It seems e3 or a kingside fianchetto is the appropriate defense. Suprisingly, the move ...Bb7 wasn't used right away by Black. Well, now I like this defense. It adds some 'flava' to the opening and I can usually throw off the opponent and in some cases win the h1 Rook. Kinda like how the h8 rook can drop in the Orangatang when the beginning is played horribly wrong. Also, since this opening is way below 30% for Black, I'm gonna stick to the good'ol Nf6... for now.


Engine note: So I ran this tournament with a bunch of engines. I downloaded some new ones too and my new favorite 'free' engine is Fruit 2.3.1. That engine is baaaaaad. I haven't squared it off against Fritz 11 because my laptop went out at home and my Fritz cd is stuck inside. I didn't have a chance to bring it to work. Still, Rybka would beat out Fritz a bunch and now Fruit is giving Rybka a run for its money. Naum 2.0 is good but I'd like to see 3.o. Now to the details:
