you didn't offend i'm just confused. I wasn't talking about 5. dxc5 which I completely agree with you is bad for white. I was asking about 6. dxc5 which as near as I can tell you agree with me is at the very least is = for white if not better. So your comment is strange in this context as you make it sound like white is in for a bloodbath with 6. dxc5.
So, in the Philadelphia Open this past weekend I only faced d4 once as black and played my first non-blitz Tarrasch Defense...AND got this line with 6. dxc5...go figure.
See below, but go easy...LOL. We were only in the U1500 section and my rating just recently went to the upper 1500's (dropped some after this tournament).

Opponent offered a draw and I accepted. Was an interesting game.
I haven't analyzed with a computer or that much on my own yet, but here are some of my thoughts:
- Talking to my opponent after the game, he considers c5 a bad move...guess because of the isolated pawn stigma. Also interesting was a comment I heard from a reasonably well known US GM talking to another player (assuming who was also in the open section) about how that player needs to avoid getting isolated pawns in his games...of course if they are just weak with no counter-balanced strengths this would be good advice.
- I think Na4 is more normal versus Ne4?
- Most games I found on a quick search go for 7...Bxc5 8. Nxc5 Qa5+ 9. Bd2 Qxc5, but after Rc1 and some piece exchanges I figure I got my pawn back but the isolani on d4 pawn loses some strength? Apparently still best if strong players are going for it though.
- 8. Qc2? Didn't seem good, just Ng3 I figured.
- 10. f3...I was expecting g3 and Bg2.
- 11. Qb3 seemed like a strong move. Threatening removing the guard on my queen.
- I accidentally repeated moves 3 times trying to gain some time back on the clock but my opponent didn't claim the draw until after we made another move or two so appeal for draw was denied.
- At move 33/34 I thought I had some advantage in the endgame as it would be easier to create a passed pawn on the queenside, but maybe not really.
- 38...b5 maybe not so good after Ra1, but I thought the way the game went was better for me.
- 41...Ra3. I looked at blocking the d-file with Rd3 but was worried about white blockading my a pawn and then still being able to push on the kingside.
- after 44 Ke4, Black must watch out for mates
- 46...Kf8, in time pressure again. I think Ke8 forces draw as white has no useful discoveries.
- after 47. Bd5, I think Rc7 was my best play but still a draw at best for Black. Black also has some mating ideas, but nothing seems to work with Re3 check. My opponent offered a draw and having not much time and unable to find a clear way to push the a-pawn, I accepted.
Hope you enjoyed this Tarrasch Defense!
