  4. Namaste, Hello thomas , I have done several tests on your engine , Nirvana chess 64 bit, and the thing I want to say is that Nirvana plays just " too defensive " , sometimes it seems that Nirvana wants a peaceful draw even in better positions instead of fighting for a win . Nirvana is able to beat weaker engines but also makes many draws against them .a good thing about playing passive and solid is that it can also make draws against super engines like komodo & stockfish but the problem is that you also wont be able to beat weaker ones. another problem is the choices for opening.Nirvana usually goes for very drawish passive lines ,which there are little advantages to achieve . and lets talk about some good points, Nirvana's understanding of the endgame , is superb. when the queens are off the board, and the engines should calculate the best ways to play with or against the passed pawns , Nirvana shows great talent. well , I can call myself a " fan of Nirvana chess" and I am not saying that you should change the " style " of chess nirvana plays , but still, you should teach Nirvana to be a little "braver " while it has the possibility . the last thing I want to say is that I am a buddhist,and of course I like the name of the engine . wish you and Nirvana be always successful .
