@ThrillerFan - The Owen Defense is not weak, it's just played wrong by most folks who employ it, because they don't properly mind the weakness at b5 (which can be managed). John Owen beat Paul Morphy, Adolf Anderssen, and Wilhelm Steinitz with it. Safe to assume it is sound.
Most importantly, I qualified this with a set of warnings, which your referenced game does not follow. The whole point is that e6 must be played first (before b6), and that c5 must not be played too soon. Your opponent failed to heed both of these.
The idea is to "bait" the e4/d4 pawn center with the look of a French Defense (1. e4 e6), then to transpose into the Owen after 2. d4 b6. Failing to play e6 denied your opponent the ability to fix the d4 pawn (I'd never let you get a pawn to d6), which made the c5 thrust particularly suspect. As Nimzowitsch teaches us, a target must be fixed in place before it can be destroyed!
Try reading the whole post, and then try to UNDERSTAND why each of the warnings are important. I've played this against very strong players, including those at your level in tournament play, and my results are just fine. Certainly better results than I got playing the Sicilian, Petroff's, or the Nimzowitsch defenses, all of which I've tried against 1. ..e4.
Second point, there is no different in principle between a transposed Owen and the English Defense. In both cases, it's the d4 pawn which is your target. Fix it, and that's what the combined action of the b6 and e6 thrusts is designed to do, then develop your light square bishop!
ANY OPENING IS BAD if you don't understand its underlying premises. Despite your opponent's high rating, it is clear that he didn't understand the Owen Defense, and had no hope of playing it effectively.
You might be able to argue allowing d6, but your whole 1...e6 vs 1...b6 is hogwash. I voluntarily played 2.d4 against 1...b6?? And always will, and NEVER will an early c4 come from me against that hogwash.
Also, he played ...e6 long before I ever played d5, so again your theory is garbage! If Black ever plays ...d5 himself, I will play e5 and you will have a bad French, having wasted time fianchettoing your light squared bishop.
Yes, allowing d6+ was bad, but Black is in trouble anyway.
There are 2 mistakes that White often makes in the Owen Defense (especially after 1.d4 b6).
1) DO NOT push c4. Against 1.d4, here it makes sense to play 1...e6. If 2.e4, then 2...d5 and if 2.c4, only then b6. The weakening of both d4 and the a5-e1 diagonal (for ...Bb4) are important! After 1.e4 b6? Or 1.d4 b6?, do not advance the c-pawn!
2. DO NOT play an early f3. This is a sucker move and leads to numerous tactics available to Black on e4 combined with ...Qh4+ ideas.
White should play e4 and d4 - does not matter which comes first - if Black is dumb enough to play 1...b6. Bd3 to follow, not committing yet to Nc3 or c3. Nf3, Queen will usually go to e2, castle Kingside, and what Black does drives Nc3 vs c3 and Nbd2.
And as for your victory claims, that was the 1800s. Nobody knew 1...b6 theory back then. Find me a legit post-1980 world champion (the computer era) that lost to 1...b6 while a GM. Karpov lost to 1...a6, not 1...b6, against Miles. Not saying 1...a6 is good either, bad game by Karpov.
Owen's Defense is garbage! Only time to play 1...b6 is against 1.c4 and only time to play 1...e6 followed by 2...b6 is 1.d4 e6 2.c4 b6. It is all about weakening that diagonal a5-e1 which in turn weakens e4 as the Knight will be pinned upon arrival, even if it goes to d2, as long as c2-c4 has been played!
This should also point out the counter to your last claim of no difference between the English Defense and Owen's Defense! They are LIGHT YEARS DIFFERENT! The advanced c-pawn's negative effect on d4 and e4 (the latter due to the a5-e1 diagonal and the ineffective Queen's Knight, removing a defender of e4 with a piece that can never directly control e4, giving Black light square dominance.
Saying the Owen and English Defenses are no different are like saying the Pirc and Kings Indian are no different! They are VASTLY different due to that c-pawn. Pirc you go for b7-b5-b4 to kick the Knight and go for e4, like in the English Defense. Kings Indian the d4 square is weak and Black attacks and controls the dark squares.
You have got it all wrong if you really thing Owen's and English defenses are the same thing.
