Obviously it was because you didn't care enough to examine the bag rigorously to make sure it was absolutely perfect before you moved with it. Case closed.

Touch move rule -- once you've begun to examine the bag for holes, you're obligated to move with it even if you find one.

I have dropped three of my black pawns, one twice ... heads came right off. I'm trying to correct the problem but until then, epoxy to the rescue.

Any hints on how to correct the problem?

Is this happening in the French?  If so, be warned: eventually the pawns will revolt and behead the queen.

hehe, in blitz games OTB, i constantly (accidentlly) knock over pieces to confuse my opponent where pieces are to win on time :)

Well, the more skilled the player is the less often he drops pieces. When he gets stronger he drops a tempo or two, or he drops an important square. Or he drops a forced winning continuation in a position that appear as if it is a drawn position when it is not. Or he drops a stale mate combination or he drops a good defensive move in a difficult situation.

The point where a player never drops anything would be the point where he never lose a game even playing against the world champion or against the best computer software available. Since that is never going to happen for probably 99,99 % of all chess players the problem of dropping something can always be discussed, and lots of frustration can appear when you analyse a game after it was finished.

The good news on this is that playing chess will continue to be exciting, challenging and great fun.

@Blueknightshade

I think you dropped a few hundred 9's there.

I drop my opponents pieces.

Interesting ...I guess not everyone has time to dedicate to chess. IF i dont drop pieces I will probably be 200 points higher in otb chess. But I drop pieces all the time. I play online otb slow blitz games usually with increment.

Occassionally I dont drop a piece and I end up defeating someone much higher rated than me. 

Now on CC i see no reason to drop pieces but it happens esp if not so into the game.

Re:  zxzyz comment #15:  Every person post is better thn I am (I think).  I drop more pieces in CC games than live or OTB.  Reasons:  not into the game; in a hurry; forget previous plan/problems; inattention due to casual play; lack of focus.

 I think it was Tartakower who said "It is always better to sacrifice your opponent's men"

With both essays and chess games, there are several problems. You can look at something for ten minutes without seeing a quiet mistake. Maybe you do not have time to check every possibility. And then there are the misconceptions- thinking that an opponent can't take a piece because of a threat that, it turns out, can be countered.

In all the above cases, experience helps. Maybe it is not a coincidence that it is a CM asking this question, as if every potential dropped piece were obvious if only we spent a split-second to look at it.

I came up with a plan for not dropping my money when drunk - spend it all on drink.

I've got the same problem. Only recently have I started playing games of decent quality in CC chess from my point of view (I've only got 4 CC games finished up to now though ), but usually when playing CC or live, I just become careless and/or lose my focus.

I drop peices when i play to fast.  when I play slow I get nervouse when I see a good move... I just cant win...  actually I can, I just mess up though...
