Can you be a winner online without a hud

Exactly. Also some HUDs like PT4 help by displaying stack sizes in BB, which save you from having to do those calculations in your head. This alone is already very helpfull, since stack sizes are so important in tournament poker. I am sure, its possible to do well without a HUD, but I am kind of addicted to mine and feel naked without it

Some networks doesn't allow HUDs (like GGPoker). GG has their own HUD but not that much detailed like other HUDs.

Unibet do not alow HUD:....no notes also....u can use notepad for that but...if u can change alias often then it is no use....
but u can win without hud i have done it in unibet....even lex has said it no hud needed...but he is a difrent from us...

I would love to be a consistent player who makes a lot of money playing online poker
