london system vs colle system vs italian game for attaking

Do not focus on attacking, focus on avoiding mistakes first.
You can only attack after you have obtained some advantage.
You do not win or lose because of the opening, but because of tactical mistakes.
Attacks are possible with the London, as well as the Colle, or the Italian.
Pick one and stick to it so as to accumulate experience with it.

I like attacking more than defending. Nobody grows up wanting to be the top defender everyone wants to the lead scorer on a football team

how to stop making blunders ?

Think about your move. Decide. Do not play your intended move, but imagine it played on the board. Check it is no blunder: does not hang any piece, or pawn, does not run into checkmate. Only then play it.

Play Evan's Gambit a variation of Italian Game.

Why is it that in bullet, i am not late in making my move, i am 10 sec. Far from my opponent and suddenly they will still out live me in time. Does checks make additional deduction in time or do my opponent use a bug to slow me down. Just asking. Thank you

At post #9 I am sorry to tell you Philippines has low internet speed causing LAG in.speed chess. Play 5/0 and slower to avoid LAG problem.
