Solving time approx. 20 mins. Another excellent offering from Orlando, with some very subtle definitions that had me struggling in places. I particularly liked 6A (a subject close to my heart) and 7D. There were two presidential candidates in there too - one from over 200 years ago and one right up to date.

Across
1 BURR,OWING - ref. Aaron Burr, 3rd vice-president of the US.
6 CIDER - hidden rev. in pREDICtions. Nice definition, “press release”.
10 H(1,B)ERNI,AN (Henri*)
11 EDITORSHIP (this period)* - took me a while to realise this was an anagram.
14 LETT,U(tter)C(haos)E(ventually).
15 LEO,POLD(er) - there have been three King Leopolds of Belgium.
17 RE(DUCE)D - the German retreat = DER rev.
22 KID,NAPPING - took far too long to get this.
25 UNF(fun*),AILING
26 OBAMA - well hidden in “jOB, AMAzingly”. Ref. Barack Obama. Will he be the first black president of the US?
27 S(t)E(e)L,BY - didn’t think I’d heard of it, but I remember the Selby rail crash.
28 SHEFFIELD - steel has been made there since 1740, whereas the football team was formed in 1867.

Down
1 BRIDE - double def.
3 OUT TO LUNCH - nice cryptic definition.
5 GA(BRIE)L
7 DR,ILL - took a while to get this. I was playing around with different combinations of DR, MO, MB and GP, convinced it was going to be A,(abbreviation) inside (abbreviation). In the end quite straightforward when you parse it correctly.
14 LARK,SPURS
18 DAIL,I.E.,S(ell) - the Dáil is the lower house of the Irish parliament.
19 FINA(G)LE - don’t know why, but I like this word!
21 OFFA,L - he of the Dyke.
24 LI(fe),L,Y

A really good puzzle from Dac today with skilful misdirection, great variety and invention, and all clear in the end.

5 B(AY R)UM

10 BUSH I DO Samurai Code (Japan)

11 ORGANON Hidden - system of logic

12 YALE “Starts here” i.e. first letters of the first four words in the clue. Though Yale entrants would usually have had some previous schooling…

13 BIG B(R)OTHER Think I’ve seen this idea used before. Even those of us who carefully avoid it all will know what the surface reading refers to, I think. Very good.

15 JO (E BLOG) GS Jogging the memory.

20 P EARL GREY A colour and a tea.

22 SKI(p)-JUMPERS

27 REALTOR (rare lot)* Equivalent of estate agent in some areas where property is known as real estate.

29 WEE-WEE Clear to the youngest solvers.

30 (TEA CHES)T trains = teaches Nicely misleading. T = originally transported (first letter)

DOWN

3 B AIL “ale” A bar e.g. holding paper on a typewriter.

4 CO (O KING) UP

6 ANGLOPHILE (help in goal)* fan chosen, I expect, as goal in is the anagram fodder. Had to think a while to see if definition “England fan” is fair. I think it is - though an Anglophile will, I think, generally not be English he or she is, among other things, an admirer of things English and admirer = fan most certainly.

8 MAN FRIDAY (in farmyard)* less r Great misleading context by linking it with the previous clue to RANCHER.

9 MO(A)B From the Bible.

14 B(L)ANQUETTE L = large (clothes size) (in Concise OED)

15 (JACK S) Tumble RAW war< Superb double use of ratings = sailors and the surface reading comments on real events, of course, I guess.

16 SEA BREEZE “See Bries” Amusing surface.

25 Anwar SAD AT TA< Egyptian president, assassinated in 1981.

26 E (PI) C Definition “very good” Pi, a 1998 film - EC London postal district. (Answer right: explanation wrong - see Eimi’s note below)
