Have you ever played a '!!' move?

here is another... my opponent believed I had dropped the queen... this one was a blitz

My opponent wasn't a bad player (around FIDE 2100 I think), but strangely he didn't even try to get the two pawns and lost very quickly without a fight. After 1.Ke2 0-0-0 I would have played 2.g4 Nxg4 3.hxg4 Qxg4 4.Rh4 Qg2 5.Qg1. It's probably not the computer's first choice, but I would assess the queenless position to be rather easily winning. I have an extra piece, all of my pieces (especially the rooks) are well placed, and his two pawns are not really going anywhere.

That's how I usually feel about things, too. I think I never attached a "!!" to a move I made, but I didn't let that keep me from posting that neat diagram above. 

You wrote: "Is something wrong with 0-0 instead of Ke2 or is that just me? If you're really worried about an attack you can trade queens with Ne5. eg. 1. 0-0 g5 2. Ne5"

The point of 1.Ke2 is to protect my rook, so that 2.g4 wins the piece. If black's bishop had been on e7, 1.Rh2 would have served the same purpose. After 1.0-0 I still retain a positional advantage, but there is no quick win in sight.

@Rumo75: thanks for the answer and the move order how to force exchange of queens in that position. That looks very promising indeed. Even the placement of the king in te centre is now an advantage for white.

Am I the only one who can't see what Rumo's move was? :s I only see the board.. no move?

It was Ke2 (from deduction from later diagrams)

In one of my recent games I played a move that turned a position that was equal into a position where my openent resigned imediatly

If that is the case he resigned in an even position.

Yeah, or he blundered in a even position, in which case, the position was no longer even. :-)

Exactly.

I loved watching this. Beautiful in my opinion. But... have you tried running it through a chess computer? According to Stockfish, every single move he made, after Qd8, was a blunder. Also, Stockfish doesn't agree with your commentary; "[Rxb7] is his best bet" -- Stockfish marks this as an absolute blunder. Also, ...f5 is what turns this into a mate. He should have played ...f6 and avoided the mate. You're still up loads in material, though, and are in for a comfortable win. :-) (but that's because of black's bad moves -- not forced)

Anyway, don't get me wrong. This is way, way, way above my level, and I absolutely loved this. Mistakes are (perhaps the most important?) part of chess, and here black did many. That makes room for aesthetically beautiful combinations, such as this. :-D

I recommend running your games through a chess computer, especially if you feel like you did something truly genius. The computer will probably give you at least one way to drag your spirit down, lol ... :-) 

This was better than the last one I posted because I could also have done it without f5.

Danieman, I don't have Stockfish, but I found some online computer to use. Have you tried actually playing it's recommended lines? I know for the online one it freaked out, saying we were equal, only a move later to say I was up 4-5 points.

I'll post the analysis in a bit.

No, I haven't, and I don't think that would have helped anything. My rating is just slightly above 1000 (blitz), and the computers marks all my moves as blunders, so me playing any lines wouldn't really give any answers at all. :-D

Looking forward to your analysis! :-)

Probably not, but at the time I think I did.  

And of course this one from years ago:

The number of !! moves I've played is zero next to the number of !! moves I thought I've played and were refuted by the computer afterwards :( This one was refuted pretty soundly
