Your favorite attacker

Tal, Morphy, Kasparov, Fischer(maybe?)

Who is your favorite attacking master?

I agree: Mikhail Tal, Bobby Fischer.  They where great!!

For my money I'd have to say Kasparov, it's hard to find someone that worked harder over a chessboard than he did. I'm a bit young for the Fischer era to have enchanted me, though I do agree with his fighting spirit to never go for a draw unless every bit of play is squeezed out of the position.

nezhmetdinov was, is, and will be the best attacker of all chess players.

  My favorite attacker chess master is Frank James Marshall(09-10-1877 to 11-09-1944) was the U.S. Champion from 1909-1936 and was one of the world's strongest chess players in the early part of the 20th Century.  Marshall was best known for his great tactical skills.
