# Puzzle of the week #272

Level:
3-Bishop
Chess Diagram:

This is an unbalanced position, meaning different kind of material on both sides: white Rook for a Bishop + 2 pawns; each player is looking for a decisive combination to win the game. Both Kings are exposed and in such cases the quicker attack wins or whoever moves first has the advantage. Black has just moved 1... Qa8 pinning the f3-Rook; this pin must be really uncomfortable, forcing white to think defence now. Your tasks:
a) What kind of pin is this?
b) Who stands better?
c) What should white do to get out of this situation?
Total available points for this puzzle is 20. The answers will be published next time together with puzzle #273.

Game NN - Gueshev, 1936. The vast majority answered properly to (a) and (c), while none could get the extra points for remembering a similar position. The answers are:

1.e4 e5 2.Nf3 Nc6 3.Bc4 d6 4.Nc3 Bg4 5.O-O Nd4 6.Nxe5 Bxd1 7.Bxf7+ Ke7 8.Nd5#

c) Black can do the same trick as in the game above. Here is Coco's answer:
1... Nxe4 2.Bxd8 ... [2.dxe4 Bxf2+ 3.Ke2 ... (3.Kxf2 Qxd1 and black wins) 3... Bg4 and black wins] 2... Bxf2+ 3.Ke2 Nd4#
