Puzzle of the week #158

Chess Diagram: 


This past Saturday I watched on TV the soccer game Vancouver - Kansas City 3-3 from MLS. The game was very entertaining and with lots of drama: 3 of the goals (2 for Vancouver and 1 for KC) were scored in injury time and Vancouver came back from 0-3 to tie the game. One of the important lessons from this game is also aplicable to chess and goes like this: opportunities appear if you play well; all it takes is to make sure you use them in your favour.
In this game White has attacked early and went up a pawn; however Black needs only one opportunity to get his deadly Bishops out in the open and regain the initiative. Your taks:
a) Formulate a plan for White who moves now;
b) Use the plan to come up with the best line for White.

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #159.

Puzzle #157 solution:
Game between unknown players, Yugoslavia 1949. This was a quick and simple puzzle, asking for a quick and simple answer. Alex did it the best:
"a) It is obvious White has the advantage. I did some analysing and here are the results:
white has pinned the Black Queen; if it moves, then it's checkmate [1... Q anywhere 2.Rxg7+ Kh8 3.Rh7+ Kg8 4.Qg7#]
white has a material advantage: two pawns
white's King looks safer because:
- White pieces are aiming strait towards the Black King
- Nothing really is attacking the White King directly
white's pawn chain is very strong (if there wasn't for the d4-pawn, Black had a chance to do smothered mate)
b) Here is the most probable result: 0-1
I'll show you why. Black really doesn't have much to do.
1... Rc5!?! (it won't give up the smothered mate chance)
2.dxc5 ... (if 2.Rxc5 Qxb7 ...)
2... Qd1#"
