Puzzle of the week #103

Chess Diagram: 


Every move require careful analysis and a well thought decision. It does not matter what stage of the game we are at: opening, middle game, endgame, nor it matters if there's still a lot to play, or the game is almost over. This week's puzzle gives you a chance to practice your analysis skills and come up with couple of important decisions. Your tasks:
a) Analyse the position (10 points)
b) Decide what should Black do: defend "Bh3" under attack, or move it to a safer place. Show what can happen in both cases (20 points)

No line should be longer than 4-5 moves, but the resulting position must be clear enough to prove your decision. A complete answer will surprise you in a pleasant way, proving one more time that chess is beautiful and rich in possibilities at almost every move!
Total available points for this puzzle is 30. The answers will be published next week together with puzzle #104.

Puzzle #102 solution:
The game under scrutiny was Levenfish - Riumin from the Moscow International tournament 1936. I am very happy to see the majority not being side tracked by the original comments. Here are the most complete and interesting answers this time around:
Andy Q:
"White's positives:
-has a Queen and Rook battery
-controls the "d-" file
-Queen and Knight is attacking near the King
Black's positives:
-Queen is in White's territory
-Threatening White's Knight
-Has a good pawn formation
White's negatives:
-Knight is in danger
-Pawn formation is weak on the Queenside
Black's negatives:
-Has not finished developing his pieces
-King is near White's pieces
Even though both Kings are well protected, Black has only a Queen attacking White's King, which is not enough to checkmate. White, however,has a Queen, Knight and potentially a Rook attacking. Also, White can sac a piece to get to checkmate such as possibly Qxf8+ followed by Rd8+ when the "e7" square is protected or sacking with the Knight. White should have played something else."

"27.Nf6+  gxf6  28.exf6 ... and White has the mate with either:
29.Qxf8+ Kxf8 30.Rd8# or
29.Qg3+ Kh8 30.Qg7#
The only escape that Black has is to give up the Queen and save the King:
28... Qxf1 29.Kxf1 Ba6+ 30.Kg1 Kh8
White missed a glorious combination."
