When do you stop playing risky?

As a player who likes unsound openings I go for gambits or attacking lines.Such as Max Lange Attack Lativian Gambit Grob Orangutan and etc.

Im rated at 970+ but before I study these lines when do these openings end up being useless what rating range do you using them and what lines are worth while.Thanks in advance to help me not waste my time in end less study.

prob. 1500+ in club games.

Garbage lines.  I'd choose a couple more reputable openings if you're going to study them.  I'm not one of those people who'll say "Don't study openings til bla bla bla, only tactics bla bla bla."  I get that openings are fun to study...and if you want to spend time on them, then choose something worthwhile.  

Never (actually I play more stupid than risky - but then I love durian....so whatever).

You sick bastard.

You stop playing risky when it is no longer working for you.

Your rated 970 and your openings are your primary concern?

Don't play bad lines - many openings have been sent to the rubbish heap because they're actual rubbish. Sharp is perfectly acceptable, gambits are perfectly acceptable, and it's even OK to play 1.b4?! here and there in blitz, but don't make that your main repertoire. Play 1.e4 with white, play the Sicilian and Gruenfeld with black, and stick to attacking games that make a little more sense. I promise that you will find rich attacking possibilities hiding in the sidelines of more 'mainstream' openings.  

Try studying tactics and middlegame startegies, that should be your main concern untill you're something like 1300. Then you'll understand the openings much better and you'll have use for them. But still at that level study tactics. Tactics tactics tactics. Focus on that.

If you need to improve your rating then move from dubious openings to reliable ones.

Also just dont over do the preparations for the openings. You need to develop tactical & positional feel for the game.

I am presenting few games with one of the most reputed openings with for your benefit:

Game 1: Nimzo-Indian Defence. I was playing black & drew with a higher rated opponent in blitz game

Game 2: I think you like playing attacking chess- so why not try Sicilian. There are many variations to it as well:

Here's a game with Sicilian Opening

Game 3: King's Pawn (e4). Legendary US chess player Bobby Fischer termed this opening "Best by Test."

In this game again, I am playing against a player with slightly higher rating. Do whatout for "Venus Fly Trap" that I used at the end to mate my opponent's king.

Hope this will help improve your skills & rating.

@Bareilly, G1 is not a Nimzo, and G3 is an especially bad game...the opening played by the Comp(which makes the game worthless) is inapplicable to any learning, really.  Not to completely shoot down your post, but even G2 is questionable at best(you played well, but your opponent most certainly did not).  

Yes in G3- the opponent played badly, but I wanted to showcase "Venus Fly trap" to prove that one can get tactical shots even with solid openings.

G1 is a Nimzo though my opponent did not procced with book move order. Probably he mixed up some moves.

Contrary to popular belief I feel that the higher your rating is the more legitimate gambits become since you actually have the tactical vision to take advantage of any mistakes your opponent makes.  

On other note, until you are literally 1800+, learning good locations of pieces and opening ideas is much more important than any theory period.  Anyone who tells you differently is either someone trying to sell a book, misinformed, or a coach who wants to get more money out of you by teaching you for more hours.    

G1 is not a Nimzo, just because you play Bb4 doesn't determine the opening.  Takes two to tango! 

Thank you for all the comments so far I've learned alot from just listening but what gambits do you tend to call "sound"?

Which one?

WOW rdecredico, how did you know he was going to ask?

No, this is spam:

in my case never. my need to be creative is way too high.

if I see something risky  but tempting I play it even it may lose a rating points.
