docile?

Dopey...

+1

Legit.

OH YEAH!

Slow and positional.

flaccid

Sharp - essentially means the position is very dynamic and/or tactical. Usually this means the pawn structure can also rapidly change. 

The opposite is solid - typically means there are few if any weak points, and typically the pawn structure is more clarified and cannot rapidly change. 

Interesting 

Thanks for the laugh - I needed it.

placid

Dull

I look at GM positions that seem dull, drawish, etc. and then when I see what they to with it to develop threats, attacks and even stranglehold mates out of that blandness, I think ALL positions are potentially sharp. Perhaps it is just the players like me who are dull and cannot see the sharpness present until someone better points it out.  

Well ok. maybe just two kings on the board is not sharp.
