Black blundered on move 3 already ;)
White's blunder is 15.Nb5??
15.Nd5 is better.
15. Nb5 was a blunder, white should go 15. Nd5 and keep fighting
wizard3.1 (free version) analysis:

position after 12...hxg5: Best move: Kd2-e3 Score: +7.27

after 13.h4 gxh4: Best move: Nb1-c3 Score: +3.39

after 14...Rd8: Best move: Nc3-d5 Score: +4.37

after 15.Nb5 Rxd2: Best move: Nb5xc7 Score: Black wins in 7 moves

before that, black's 2...Bb7 (Score: +7.26) was a blunder; best move was g7-g5, score +0.78

In terms of perfect play 1.e3 b5?? is a blunder...in the same sense it is used in #6 for 2.Bb7...1.e3 b5 2.Bxb5 Bb7 has been proven to be a forced white win since at least Nilatac's time so anyone who indeed uses Nilatac for analysis or cheat with it should never play it.

However as long as both sides do not cheat this is a playable move.
cat_person: sure Bb7 is a solved win for white that is intractable for humans to follow, but i would argue that it is at least a mistake compared to say Ba6/e6/Nh6. it creates complications but once you find the main line Bxd7 Bxg2 Bxe8 Bxh1 Bxf7 Bxd2 Bxd2 (or Kxd2) Bf3 Bxg8 Kxg8 Qxf3 Nd7 Qxf8 Nxf8, which i've played on the white side loads of times, black can't make progress unless white makes a mistake.

some nilatac lost openings are definitely playable like 1.c4 d5 but i'd argue this isn't one of them.

fabrice liardet treated the opening here in french http://www.pion.ch/Losing/suicide.html

english translation: "...by playing 1.e3 b5 2.Bxb5 Bb7?, and it's that which we call the 'suicide defence'. as the name of the variant indicates, this combination(*) is much less efficient than against 1.d3 and is worth very little to experienced players; it remains very popular among beginners. certainly black magnificently ventilates their position, but they keep far too few pieces, and in particular they lose their king."

and http://www.pion.ch/Losing/game0.html

english translation: "the inexperienced player could say that things are going well for black; in fact their position is catastrophic as they have absolutely no plan and can only content themselves with watching white advance quietly. at most, black can hope to choose their method of losing: to find themselves in zugzwang with a trapped piece, or to give their pieces and be satisfied with advancing their pawns to a fatal promotion."

(*) when i learnt french in school i was told a "combinaison" meant a wetsuit... going to guess that it means combination here instead haha
#9 I'm inexperienced..so I agree with you..

But for engines..my standards are very high. Any engine that plays anything other than 1....b6 to 1.e3 is a very bad engine since all of them are theoretically forced white wins which are usually impossible for humans but is included in a database less than 1GB for a computer. Hence I dislike almost all existing anti engines.
