Its the poisened pawn ,so one could add several pages of analysis to just about every move
27 Rd7 seems to be white's last mistake.
27 Qa4 Ba4 28 Bh5 Bd129 Kd1 looks like a draw.
interesting is 22 Qe4 ( a suggestion from Thomas Luther,afaik) but i think you have to do some homework after 22 .. Ke7

Look at this book loss, and I was using the old book from Wael...

It's not a book lost at all,until the 18th move,Romi was playing the top moves of this variation marked in the Fritz 11 opening book
It's just that Romi didn't understand the position and lost....
Please post more of these games,personaly I think that Oxygen is using a commercial opening book against you....

BTW,when did Romi get out of book

[Dr.Wael Deeb]

Actualy,until the 24th move,Romi was playing with Fritz 11 opening book lines,everyone who has the program can check it....
And here is a quick analysing lines from Fritz 11 after Romi's 24th move:

27. Rxd7??

It's not a book lost Tony,definitely not....

[Roman Hartmann]

27. Rxd7 seems to be the losing move. Hard to believe an engine would come up with this move though. There might be a bug.

Roman

[hawkeye]

is oxygen still private or can it be downloaded? if it can be downloaded where can i download it from?

thanks, steve

Definitely Roman....

[Tony Thomas]

I can assure you, Oxygen isnt using a commercial book, its using a polygloat book instead, and I kind of goat my hands on the book after a lot of begging..Oxygen is still a very private engine, Robindu told me he that he will send it to me once all the processor specific problems are resolved..I am pretty sure Romi goat many bugs, the bugs actually show up more when its running under chesspartner interface due to its lack of full support of WB protocol. Its also possible that Romi has pondering problems, all of my Romi tests are ponder off except when she is on ICC..Good thing the account is not meant to chase rating..

To look at the quality of the book here is an incomplete game against Arasan..

Aha,I see now....
And yes,it's a chess engine/GUI communication problem as well as the pondering issue....
Romi plays in my tournaments with it's current opening book and it had never came out of it with a bad score....
