Perenyi Attack Game

12.a3?! or what you played 12.0-0-0!?
12.Bd4 is much stronger because... I'm sure you can tell me why. I would be very interested in your explanation of 12.Bd4

kenible:
Maybe 12.a3 and 16.Kb1 were good, but my idea was to have two threats:
trying to trap the Queen in the corner, with bishop, rook and Queen white, and at the same time having the threat over the e column.
I think Bxd6 would give me initiative, black Queen was so isolated..
transpo:
12.Bxd4 wasnt played.
I think you mean to make discovered check, atacking g7 square, but i think Bc5 puts much pressure on e column with bishop and Queen and checkmate threat.

I realized 18. Bxb4 was a bad move, when black played 20..a5, allowing black's Queen to get away from the trap...

Maybe I am just not experianced, but could you not have completed the trap by moving your rook to 1A @ move 21

Very interesting game! I've played something very similar with the knight sac on d5, and i think that is one of my favorite games i've ever played. i think so far i'm 5-0-0 with the perenyi attack...i'm in love with it! very easily to mess up and get slaughtered though.

I want to add something about your Bxd6 idea, though. I think that in this case, black can simply force a draw, which he probably wants! Actually, white has no choice but to go along with it: I added it as a side line, along with more in-game comments.

Nice analysis mottsauce!
I think that's the idea why i avoided Bxd6, i wanted to avoid the perpetual check.
what about 12.Bd4?

I like Bd4, but I tried analyzing it and I came up with a mess!
I think that after Bd4, black only has two choices to save the bishop on e7 (otherwise white will play Qe3 and Re1). Note that Qe3 covers a7 so black can't just move the knight and play Ra7 to defend.
The two choices are, I think, Qa5 and Kf8. Qa5 has the idea of Qd8 to support the bishop on e7, but in this case the g7 pawn hangs, and now even castling is out of the question.
Really, ugly as it is, Kf8 might be the best option...not sure.

crap, i missed something.
Bd4 loses. Nc5! followed by Bf5! and the mate threats on c2 are too much to ignore.
Bd6 is unequivocally best, going for the draw.
yikes.

You might want to take a second look. The score is 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e6 7.g4 Nc6 8.g5 Nd7 9.h4 Qc7 10.Qe2 b5 11.Nxc6 Qxc6. After 12.Bd4, Black's dark square B is still on f8 not e7.
