I think white has very little, if anything, after 14...Nd7! 15.Bf4 Nxe5 16.Bxe5 Bd6, when white has a tough time to achieve something with either 17.Bxd6 or 17.Rfe1.
I think Karpov's manouvre 14...Bd6 15.Bf4 Ne8 gives white a very unpleasant initiative- factly, I have won every single corr. game I have played as white.



Actually the main game is still in progress, but this is out of inertia- the final position is a tablebase win. Muhl defended very inventively an extremely difficult position, and he should have earned a well deserved draw after 56...Kb8 (instead of the catastrophic 56...Kb6??), and one move earlier, 55...Rxe3+ also draws (although your engine will disagree) - it's a very nice position, well worth an endgame study.
Not much to comment on the other two games- Black were effectively "stalemated" on the board, the final positions are comical.

19.Bd2 is the move there and a corr game of mine went 19...Qxc4 20. Rfc1 Qd4 21. Be3 Qa4 22. Nc5 Bxc5 23. Bxc5 Rf7 24. Rd1 Rc7 25. Rd4 Qa5 26. Rd8 Rxc5 27. Rxe8+ Kf7 28. Rh8 Qc3 29. Qd1 Qe5 30. Rc1 Rxc1 31. Qxc1 Rb8 32. Rxc8 Rxc8 33. Qxc8
there has to be a better defence than this (for example: 24...Bd7) but it's not easy for black at all, that g2 bishop is a monster

I noticed several titled players playing 5...d6 just recently.  Incidentally = or unclear with best play was the view of it in old-timey sources like Bagirov in ECO and Emms in NCO.

Regarding c5 and c4 against the Karpov thing, I noticed this:

after 15.Bf4 Ne8 16.c5 Qxc5 17.c4 my score in correspondence chess is 4/5: 3 wins and 2 draws
so yes, I think white is better

when I recently looked at this, I couldn't find any advantage for white after 5.Nf3 d6, planning b6 in most lines but now e4 can be met with e5

I dont play this with any side so I have no idea but White has slightly more space and play at bfile and blacks pieces are crawling at the back rank, but on the other hand White has also a double pawn.
Houdini 4 calls the position 0.08 at depth 28 so there are no obious advantage to White, if there are any.

In the line 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 O-O 5. Nf3 c5 6. dxc5 Na6 7. g3 Nxc5 8. Bg2 Nce4 9. O-O Nxc3 10. bxc3 Be7 11. e4 d6 12. e5 dxe5 13. Nxe5 Qc7 14. Qe2, I have come across 14...Nd7 in a couple of places recently, portrayed as favorable for White.  Is there supposed to be a problem with 14...Bd6 15. Bf4 Ne8, which was considered adequate when Karpov played it back in the dark ages (1990s)?
