What difference does it make if the player is strong if you are using (even encouraging) chess engines? I don't get that at all.
What is strong enough for the human player in your book? I love to play the white side of the KG. I have some pretty impressive (and high rated) victories using it in OTB chess.
While to super computers can finagle out a miniscule edge for black (likely) in many lines of the KG (especially accepted), many human players falter under the relentless pressure hour after hour.
In the KGD, it's a different matter entirely. I think those lines stink for black. It is like giving white an automatic edge.
To answer your questions:
I played the strongest chess players I could find up to over-the-board master.
This exhibition was based on both sides using chess engines. A player with a chess engine is stronger than chess engines alone.
In this exhibition we found some very good lines for Black. Lines that can be used over-the-board.
For any opening [including the Kings Gambit in this case], it is not so good to play White knowing there are lines where you get a disadvantage from the opening. [it does not matter if you think the lines stink or not]
The lines are quite easy to play for Black and White has to fight to try and draw.
Black has at least one dozen ways to a good game in the King's Gambit (the counting was done by GM Short, who's playing the white side pretty regularly) and about half of them are in the declined lines: 2...Nc6, 2...Nf6, 2...Bc5, 2...Qh4+, 2...d5 3.exd5 c6, 2...d5 3.exd5 exf4, and so on. To claim "In the KGD, it's a different matter entirely. I think those lines stink for black. It is like giving white an automatic edge." you need first and foremost a fat arse- else where you could pull that big thing out of?
Finding an easy, risk free edge for Black, isn't an easy task, though.
IMO Black's best chance is in the rather forgotten line 2...exf4 3.Nf3 Nf6! which I may (or may not) analyse in my blog in the foreseeable future.
Oh...and yes. In case someone has not understood that yet: engines are quite useful for analysing. I won't charge you for that piece of info this time...
Engine use during games: Not even once.
I would love to see an analysis of 1. e4 e5 2. f4 exf4 3. Nf3 Nf6! by pfren or anybody else as I think it gives Black some advantage.
What is your point?
Wow, I've played the KG for many years. This feels like the same group that disparages the Morra gambit and yet its' scalps are legion.
I don't ever recall having any game where I struggled as white against 3. --- Nf6. I would love to see the analysis.
As white I have ventured both 4. e5 (most direct, but probably most tricky for both sides), and 4. Nc3. I think white get's a big center.
IM Pfren - you are clearly a stronger player that I, so I say what I say with humility and respect. Also, I have taken up running again lately after a hiatus to work off my phat arse.
Oh, and 1. e4 e5 2. f4!! () Qh4+ ?? stinks for black if white plays correctly. I have played many of those games against players from 1000 - 2000. Don't recall a single loss.
3..Nf6 is what I hate seeing the most as white. It's really annoying because I feel like I'm down a pawn but am not getting the usual central pressure.
Even as a King's gambiter as white I know its not the best or most solit. yet not many people actually know how to handle it (on either side if we're completely honest) and hell its fun to toss caution to the wind and say "I'm going to attack all game, I dare you to stop it". all I want is to have fun. and I accomplish that
