Reinfeld position #422White to move
Here's what I came up with in about half an hour.
Static analysis - White is down two pawns for far superior development and an attack.
Before listing candidate moves, I wanted to check Black's counter-play so by null-moving White we can see that 1. ... Qa1+ 2. Kh2 leaves the Black Queen attacked and compelled to move - handy if for example Re8 is attacked at the same time.
Candidate moves.
A. 1. Qh5 - mating attack
B. 1. Ng4 - double attack on the Rook and Queen
C. 1. Nd5 - triple attack, Nxc7xc8 also threatened
D. 1. Rh6 - to break up the castle, mating attack
E. 1. Nf5 (or N-other) - discovered mate threat
F. 1. Rxh7 - mating attack
My analysis, starting with the variations that look simplest:
A. 1. Qh5 Qg6 2. N?? Rxe2 3. Qxe2 Qe6 Black looks ok - Crafty gives White a small (+1.5) advantage.
D. 1. Rh6 gxh6 White has nothing more, Black is winning. Actually crafty gives Black a winning Queen ending at depth 14 - 2. Nd5 Qa1+ 3. Kh2 Rxe2 4. Qxe2 Nd7 5. Qe8+ Kg7 6. Nxc7 Rb8 7. Nd5 Qd4 8. Bxb8 Nxb8 9. Qxc8 Qxd5 10. Qxb8 Qxa2
F. 1. Rxh7 Kxh7 2. Ng4 Qa1+ 3. Kh2 - the Queen is not attacked in this line, Black is winning. Crafty gives 2. Nd5 but agrees with the basic idea for Black.
E. 1. Nf5 (or other, ie. 1. Nc2 would have the idea of preventing Qa1+, which we've already demonstratred is unnecessary) 1. ... Rxe2 2. Nh6+ gxh6 3. Rxh6 Qa1+ etc, Black is winning.
So to the crucial variation - I didn't analyse 1. Ng4 due to time constraints and because at sight it's a 'lesser version' of 1. Nd5, that is, if Nd5 doesn't work 1.Ng4 probably won't either and White will be playing the best move so far 1.Qh5.
Black has two replies to 1.Nd5, 1. ... Qc6 and 1. ... Qd8.
C1. 1. Nd5 Qc6 2. Nxc7 the Knight should escape after Nxa8 netting a whole Rook and if something like 2. ... Na6 3. Qxc6 wins lots of material. Crafty is at about +4 after 2. ... Rxe2 3. Qxe2 g5 4. Be5 Nd7 5. Nxa8 Qe6 6. f4 Nxe5 7. fxe5 Qg4 8. Qd3 Qf5 9. Qd8+ Kg7 10. Kh2 Be6.
C2. 1. Nd5 Qd8 2. Bxc7 Qd7 3. Qf5 White is trying to deflect the Black Queen from defending the Rook 3. ... h6 4. Rxe8+ Qxe8 5. Ne7+ Qxe7 6. Qxc8+ Kh7 7. Qxb7 and White is better - although there's still some work to be done for the full point.
Fred's single variation solution is:
1. Nd5 Qd8 2. Bxc7 Qd7 3. Qg4 Re6 this is the plausible but unforced move which leads to a pretty finale illustrating some tactical motifs. Crafty plays 3. ... f5 with +5.5 4. Rxe6 Qxe6 5. Nf6+ Kf8 (Qxf6, Qxc8 mates) 6. Bd6+ Qxd6 7. Qxc8+ ke7 8. Ng8#.
In the end, it was nice to find that Crafty agrees with my C2 variation with 3. Qf5 h6 instead of 3. Qg4, but the reason is that the iron monster forces a mate I didn't see.
Crafty: 4. Rxh6 gxh6 5. Nf6+ Kf8 6. Bd6+ Kg7 7. Nh5+ Kg8 8. Qf6 Qg4 9. Rxe8+ Kh7 10. Rh8#
Reinfeld position #422Crafty's final word (after 6. Bd6+)

hi simian.. since no one is commenting on your hard works for the blog. I'd like to do some. I find your analysis great. But sometimes I think you are doing more line analysis than time analysis. Especially in a real time game. I like the idea of solitaire chess (I think you already know what it means, when I was a kid I used to read Freds book to and I think he was the first person who coined the term). But I'd like you to keep in mind of time analysis (especially in standard). Time analysis means, you figure out the amount of time left in your clock to do the best possible analysis a human may possibly be able to do given that time (it won't turn out to be the best line, but it will be the best line given your available time.. this is something hardly practiced). Your blitz is good, its way better than mine and you can use that to your advantage in endgame of standard. As for middlegame and opening I think if you add a little degree of freedom in your play. Try for instance things that are not orthodox or not common in chess but yet may be practical e.g. try opening where you develop major pieces before minor ones.. try opening pawns protecting the castled king.. etc., see if this will open new dimension in your gameplay. I'd like to see a little of that in you.
I'd like to comment more of your blogs, because I think you deserve comments for all the hard work you put in making the blog and doing your analysis.

PS: Another thing you can also try is doing a small memory practice every now and then.. I will write about that in my next comment.
By the way.. maybe wordpress is now a better blogsite than blogger.com.. I've been doing some experiment there.. if I really have the time to make a good chess blog like you I'd like to do it there.. though Im not sure what its exactly capable of, but I see its simple and doesnt load slow as most blog site do.
