Can a pinned piece still attack a King?

So, check out my final position (black).  I won this game, but only because my pinned bishop on e2 was able to attak the white King's escape route on f3.  However, I can't move this bishop, so I guess a pinned piece can still give check.  Just never realized it before.  This was one of the more interesting games I played.  If you want to see some strange things, please look it over.  Also, I tend to get killed by tricky openings like this one... some how I managed this time, but what do you recommend against these white Queen openings?

Above is an example of the opening trap I always fall for... please help me.  THanks!

On the second move, play Nf6 instead of g6. That will prevent Q moving to d5 to take the rook.

Also, yes a pinned piece can give check.

A pinned piece can give check, but only if removing that piece doesn't put you in a check position yourself. So if a bishop is pinning your own bishop to the king, you can't move that bishop for a check, checkmate or any other move :P

If it's pinning your bishop to your queen for example, you can move it all your own bishop all you like.

On a side note, in the first game, 23. Qd1+ forces checkmate. And 26. Qxf1# gives it.

You can't move a piece that's pinned to the king, but it still can check the opponents king if it doesn't have to move to do it.

Am i the only one crying over 26. . .Bxf1

Aw, we all made mistakes like that at one point :P

Whoops.  now I see that Q f1 is mate. oh well it was a 10 min game, mistakes happen.

I'm not trying to be mean. I can remember making those same msitakes. And it wasn't all that long ago. 

However, seeing it now, and having a cringing reaction to it brings a smile to my face. I'm sure when he sees it next time, he'll smile too, and deliver mate. 

no worries.  I am glad you pointed it out.  I don't analyze my games often enough and that blunder clearly tells me I need to do this more.  Also need to quit playing blitz games and more slow games.
