If you don't know whether it's playable, then it probably is. If you can't refute it, then it is unlikely that your opponent will. Everything's playable at some rating (I once saw a guy play a fool's mate because he had to go somewhere and wanted his opponent to win quickly, but his opponent didn't even see it). Until you start playing opponents that the openings don't work on (probably in the 1200-1500 range), then yes, they're absolutely playable.
Lolli and Fried liver Attacks: Are they Playable?
What could the opponent have done to stop the attack?
You will learn soon, when you play against a stronger opponent.
he could have played knight to a5 instead of knight takes on d5. Usually i never get knight takes d5 on the board, usually my opponents all play knight to a5 or knight to d4.
26. Qd3#. If you can't see that, forget the openings.
Lol, when looking over the game I was thinking, "Why not 26. Qd3+ skewering the queen?"
I didn't even notice it was mate 
For the record, I have played as Black 5...Nd4 (5...b5 is more or less the same thing) for decades, and have an almost perfect score with it. However, I think that 5...Nxd5 is better, at least practically- 5...Nd4 is definitely bad.
5...Na5! is best of course, but 5...Nxd5 is better than most people believe. With best play (Lolli's 6.d4!) white has no more than a moderate advantage, and the critical position is not well analysed yet (Houdini looking at it casually claims Black is equal, which is surely wrong).
i had played a game against pfren and lost badly in the fried liver but i dont have the game anymore do u have it pfren?
Yes, I do have it. Here it is:
Not very interesting, factly I barely played a move of my own... this variation has been analysed at Chesspub, and found unacceptable for White. 9.a3? is just a bad move, but white can keep the game rolling by other means (9.Qe4, 9.0-0 or 9.Bb3).
Does 11. Bxd5+ instead of Nxd5 give white anything?
11.. Ke7?? 12. Qf7+ Kd6 13. Ne4#
11.. Kd7 12. Qf5+ Kd6 13. Qf7, how does the king escape?
11.. Kd6 12. Qf7, as above?
These two openings have horrible names. Just because of this I wouldn't play them in hell. When I was a kid I had Black in that variation of the Italian Game that you call "The F&%# L&*% Attack" and I beat the guy!
Been toying around with both of these openings recently, and have had pretty good success with them, but I'm worried that I simply haven't played opponents who know the refutations. Anybody have thoughts on them? Here's a game I played today: What could the opponent have done to stop the attack?
