How about it's playing strength? Boris? Kev?

How about it's playing strength? Boris? Kev?Doesn't have much of an opening book (if any) but played the opening ok. I didn't play a whole game.

I had a quick play around with it and it seems reasonable. I fed it the chance to play some simple tactics and it found them all. A couple of things I noticed (admittedly on a small sample and with fast play) -

It doesn't seem to place a lot of emphasis on King safety, a couple of times it was happy to leave its King sitting in the middle on a fairly open board and eventually have it checked.

It seems prepared to swap B+N for R+P on f2 or f7, it did this once itself and on other occasion when I "threatened" to do it myself it defended f7 again.

It seems to have a limited opening book, it always e4 with e5 for instance.

I can't find an option to play Black. I also couldn't find an option to promote to piece other than queen, and furthermore there should be an option to hide the best line display as this gives the player a hint. I would say its playing strength is not more than 2000; after two games, I'm not beating it but having little trouble reaching easily drawable endings. It seems fairly indifferent to pawn structure weaknesses.

As an exercise in pointless sadism I paired it against Fritz11. It was basically lost from move 9:

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Bb4+ 5.Nc3 d5 6.exd5 Nxd5 7.Bd2 Nb6 8.Bb3 Bg4 9.h3 Be6 10.Bxe6 fxe6 11.Nxe5 0-0 12.Nxc6 bxc6 13.Qg4 Qe7 14.0-0 a5 15.Rae1 Rfe8 16.Re4 e5 17.Rfe1 Nd7 18.Rc4 c5 19.a3 Bxc3 20.Bxc3 g6 21.f4 Qd6 22.Rce4 h5 23.fxe5 hxg4 24.exd6 Rxe4 25.Rxe4 gxh3 26.dxc7 hxg2 27.Re7 Nb6 28.Rg7+ Kf8 29.Rxg6 Na4 30.Rd6 Ke7 31.Rd8 Rc8 32.Bf6+ Kxf6 33.Rxc8 Nb6 34.Rb8 Ke7 35.Rxb6 Kd7 36.Rc6 Kxc6 37.c8=Q+ Kd6 38.c4 Ke5 39.Qxc5+ Kf4 40.Kxg2 a4 41.Kf2 Kg4 42.Qe5 Kh4 43.Kf3 Kh3 44.Qg3# 1-0

I just effortlessly slaughtered it with a kingside pawn roll despite needlessly blundering the exchange along the way. With white pawns on f5 and g6 and black pawns on f6, g7 and h7 it actually exchanged on g6 allowing my queen to infiltrate to h7 with forced mate in not very many when it could have kept me out for much longer (and may not even have lost) with ...h6.

Compared to others available I wouldn't say it's "very good" at all; the Queenside one was way better.

Still probably not too bad for only three weeks' work, especially if starting from scratch.
