losing against Stockfish

[lucasart]

For fun, I just played a game against Stockfish. I wanted to know how much of it I could hold, without any cheating:

• Time 15'+15", no takeback, no viewing of computer PV line, or even its evaluation, only the board was visible.
• To give myself some advantage, Stockfish plays without any opening book, and I played with the white pieces.

Of course, I tried my best to play some solid and boring chess, and avoid any complication:
[White "lucas"]<br> [Black "Stockfish"]<br> [Result "0-1"]<br> [TimeControl "900+15"]<br> <br> 1. d4 e6 {-0.18/28 45s} 2. c4 {11s} Nf6 {-0.14/26 20s} 3. Nf3 {7.4s}<br> b6 {-0.09/26 13s} 4.

The game losing blunder was here:
r2r2k1/1b2qpp1/1p2p2p/p1n5/8/P1R1PN2/1PQ1BPPP/2R3K1 w - - 0 17
It is so tempting and natural to play b4, kicking the knight away... But, Stockfish obliterated me in just two moves, after I played it:

17... Be4!
r2r2k1/4qpp1/1p2p2p/p1n5/1P2b3/P1R1PN2/2Q1BPPP/2R3K1 w - - 1 18
Hum... where does the queen go now ? There's no Bd3, and Qb2 loses (at least) the exchange, so Qa2 is what I played. Perhaps Qb2, losing the exchange, was the least of the worst, but I did not foresee Stockfish's next killer move...

18. Qa2 axb4!
r2r2k1/4qpp1/1p2p2p/2n5/1p2b3/P1R1PN2/Q3BPPP/2R3K1 w - - 0 19
Black threatens to push the pawn, white can't take the pawn, Rc3 is lost no matter what white plays. May as well play Rc4, hoping to consolidate a bit after losing the exchange...

19. Rc4 Bd5 20. Qb2 bxa3
r2r2k1/4qpp1/1p2p2p/2nb4/2R5/p3PN2/1Q2BPPP/2R3K1 w - - 0 21
OK, it's totally hopeless now. May as well do sepuku, and die like a samurai:

21. Qxb6 Bxc4 22. Bxc4 Rdb8
rr4k1/4qpp1/1Q2p2p/2n5/2B5/p3PN2/5PPP/2R3K1 w - - 1 23
OK, I resign...

Nice experiment, btw b4 looked so natural to me too I am also going straight to the trap . Would you fancy a game on playchess? I am a ~2040 rated player, we can try some quick time control (3+1 for example), if you are interested
