Subject: How would you proceed from this middlegame position?
I recently achieved this position after a funky blitz opening in which
White has a distinct advantage (later confirmed with Fritz +0.91.), but
somehow 'lost the thread.' How would you proceed?

[Event "ICC 5 0 u"]

What plan should I be thinking about here?

19. Nd5! is a big improvement in your 2nd variation. looks winning.
so I guess pushing e5, opening the center, and capitalizing on my space
advantage and better mobility gets a gold star. thanks a lot!

Black can do a little better with 19...Qc6 defending the d-pawn and
threatening Nxe5. White has an advantage after 20. e6! Ne5!

20...fxe6 opens the 7th rank and is the main idea of e6. 21. Qg5! (plan
Qe7+) 21...Re8 (21...exd5 22. Qe7+ Kg8 23. Bf3 and wins) 22. Bf3! h6 (or
22...Qa4 23. Rae1 h6 (23...Qxc4 24. Nc7 Rg8 25. Nxe6+ Kh8 26. Bd5 Qb4
27. Nd8 +- plan Nf7+/Qh6 mate; 23...Qxa2 24. Nc7 Rg8 25. Qe7+ Kh8 26.
Nxe6 plan Ng5 26...h6 27. Ng5! hxg5 28. Qxg5 and Black will be mated
soon.) 24. Qg3 Qxc4 (24...e5 25. Be4 Re6 26. Qf2 +-; 24...Ne5 25. Rxe5!
dxe5 26. Be4 g5 27. Qxe5 and again Black is mate soon) 25. Bh5 g5 26.
Qxd6 and Black can't save the Re8 because of Qe7+.) 24. Qg3 Ne5 25. Nf6
Nxf3+ 26. Rxf3 Re7 27. Nh5+ Kh7 28. Rf8. Black is helpless against
Raf1/R1f7+/Qxg6, the immidiate threat is Nf6+/Rg8+/Qf4 mate.

21. Qg5 h6 22. e7 Re8 23. Qf4 (threat Nf6+) 23...Kg7 24. Nf6 Rxe7 25.
Nh5+ gxh5 26. Qf6+ Kh7 27. Qxe7 Be6 28. Rad1. White will win d6 and has
a material advantage. White can defend against a counterattack on the
g-file (Rf2, Bf1).

Another idea in the initial position would be to push the e-pawn to e6,
cramping Black on the queenside and attack through the central files or
on the kingside. This plan is particular effective if Black doesn't
trade on e5.

For example 16. e5 b6 17. e6 Nf6 18. f5 with the plan to open the f-file
and the diagonal d3-h7.

I like the idea of opening the center and getting the rooks in play,
but 20... Qe5 looks strong in your continuation above.

I've come up with a better variation.

1rbq1r2/1p1nppkp/p2p2p1/2pP4/2P1PP2/2N1Q2P/PP2B1P1/R4RK1 w - - 0

16. e5 dxe5 17. fxe5 Qc7 18. d6 exd6 19. Nd5 Qd8 20. exd6 Nf6 21. Qg5
h6 22. Qe5 Re8 23. Ne7 Bf5 24. g4 Be4 25. Qxf6+ Kh7 26. Qxf7+ Kh8 27.
Nxg6+ Bxg6 28. Qxg6 {and it's pretty much over for Black at this
point.}

This is further evidence that Qc7 is a bad move. This time, it only gives
White two tempi but that's still two too many and Qc7 is hardly forced.
Your brain's alpha-beta routine should have pruned Qc7 by now. :-)

FEN "1rbq1r2/1p1nppkp/p2p2p1/2pP4/2P1PP2/2N1Q2P/PP2B1P1/R4RK1 w - - 0

This is a beautiful position you have as White here. The plan is
simple...push the pawn chain up to expose Black further. One could try
this...

16. e5 dxe5 17. fxe5 Qc7 18. d6 exd6 19. exd6 Qxd6 20. Rad1 Qc7 21.
Nd5 Qd8 22. Qc3+ Nf6 23. Rxf6 {is one possible brutal variation that
comes to mind.}

That's rather wishful thinking, though. Black has given White three free
tempi by letting his queen get kicked around -- it's not surprising that,
in such a sharp position, White can get a strong attack going.

Black's fundamental problem is that the knight's on a truly awful square
where it blocks everything in. The d6 idea is much less powerful after
something like 17...Nb6 18.d6 exd6 19.exd6 Be6.
