A tricky way to beat the RUY!?

I was thinking about this line before i went to bed.Do you think it looks good?

i see you are intending the typical trap Nxe5 Qg5 - okay but you should think about the main line 4. Nxd4. :P

in the diagram position white can play O-O or Nxd4 or something with an advantage.

Yes i thought about that but after exd4 white has to get rid of the d4 pawn if he wants a good position.

The Opening Explorer database shows white winning around 50% with 4. nxd4, black with 30%.  You might catch someone on an off day with it though.

It's the Ruy Lopez, Bird Variation. And it's time to advertise my favourite chess blog. Dana blogs chess (series on this opening).

After 4. Nxd4 exd4, white has a better endgame if all the pieces come of the board. He has a kingside majority and some space. However, his bishop is floating in empty space and the black d4 pawn is cramping. Black will play strongly for ...d5 in most lines, while white has to take his time with reclaiming (or playing around) the centre, when black will sometimes have double isolanis but usually space and dynamic play.

Psychologically though, it's almost black's win, since white will have none of his usual Ruy Lopez space/centre/positional squeeze/typical plans and will have to play it on the fly. Which of course is better for you if you already understand black's plans.

Yeah, in this case, White's position is still decent. While Black's d4 pawn is advanced, it can't really safely advance, and it's not that easy for Black to support the pawn. So Black's position isn't really as good as it looks at first blush.

White would have to be a craven cur to be psychologically beaten by the Bird.  However, it does appear that 5...g6 is under analyzed and might actually be better then 5...Bc5 or 5...c6.

By the way, we are all on the same page that 4.Nxd4 exd4 5. O-O is overwhelmingly the mainline?

I agree 4. Nxd4 exd4 5. 0-0 is probably most common and best. After which 5...c6 is OK to gain time and prepare the ...d5 break, and 5...g6 (underanalysed, and because it's not forcing it's difficult to refute) looks like a good plan to support d4 and delay/exploit c3 by white. 5...Bc5 just looks strange to me, although it's apparently a mainline? I mean, what's it looking at? It doesn't look particularly nasty even after a ...d3 sac.

Also... craven cur. Heh. I like that phrase.

I suppose the point of 5...Bc5 is simply to get the piece out and out of the way. After 5...c6 6. Bc4 d5 7. exd5 cxd5 8. Bb5+ Bd7 9. Re1+ Be7? 10. Qg4 is a problem so Black has to play 10...Ne7 with slow kingside devolpment. Trying to reverse the move order with 5...c6 6. Bc4 Bc5? loses a pawn to 7. Bxf7+. Contra 5...Bc5 6. d3 c6 7. Bc4 d5 7. exd5 cxd5 8. Bb5+ Bd7 9. Re1+ Ne7, which looks about equal.

You should never move your minor pieces twice before move 10

Incorrect.

I have played the Bird variation for some time and I have totally given up on it. Play at your own risk.

for example

How about this trick line with Qg5?

(I in no way endorse this line; it's terrible.)
