2B0301 1. ... Qd1+ and now if the king goes to a2, b2 or c4 then 2. ... Qe2+ forks the king and knight. If instead 2. Ka3 Qa1+ skewers the king and the rook.	_____	2B0302 1. ... d5 prompted resignation because not only does it threaten the knight on c4, but it threatens discovered check with moves like 2. .... Rxf2+ threatening the queen.
2B0303 The best way to trap the knight is to play 1. ... f4. White can't stop 2. ... g6 winning the knight, although he could sacrifice the knight for two pawns.	_____	2B0304 1. ... Qxd5!! is a great defensive combination. If 2. exd5 then Bxf5 and black hasn't won material but he has kept his king from getting mated and is in a won position.

2B0305 Playing as white I screwed up here. Fortunately black didn't see the correct move. The move is 1. .... d2! and how does white stop the pawn from queening on move 2.	_____	2B0306 1. ... Qxf3!!! if 2. Qxf3 Rxe1 mate. Else Black has the threat of Qg2 mate. This is a tough problem to see. Almost as effective (but not quite as good) is 1. ... Rxe1+
2B0307 1. ... Rd8+ mates next move. if Ke7 then 2. Qg5 mate. If insteand Kc7 2. Qb6 mate! Ed Boardman vs. John Coffey, analysis of a variation of a speed chess game from the summer of 1991.	_____	2B0308 1. ... Rc2 and white must give up his knight if he ever wants to move his rook again. 2. Rd8 Rxc7 wins. If the rook just sits there then the black b pawn pushes down for a Queen

2B0309 Although black can win with 1. ... Rxe1+ 2. Qxe1 Qxh2+ it will take a few moves. Much faster is 1. ... Qxh2+!! and now White either loses his queen or falls for 2. Qxh2 Rxe1 mate!	_____	2B0310 1. ... Bxf4 2. Kd2 (the only move that prevents loss of material.) 2. ... Bxh2. Black goes from being down 2 pawns for a bishop to having 4 pawns for a biship and a better endgame.
2B0311 1. ... Kxh3 2. Kc5 trying to win the b7 pawn or 2. Kd5 trying to win the f7 and g7 pawns. In either case it takes White at least 8 moves to queen a pawn and it takes black 7, possibly queening with check.	_____	2B0312 Black is going to get hurt on the king side if he does not take immediate action. The solution is to play 1. ... Nxe4 winning a pawn. Now if White takes then knight on e4 then 2. .... Rxd4 is better for black.
2B0313 [solution]	_____	2B0314 [solution]      [Next]
2B0322 [solution]	_____
2B0313 Although black is ahead a piece, he has to be careful because white is threatening Rxf7. (The white rooks are very well placed.) But 1. ... Bd4 threatens both 2. ... Bxa7 and Rxf2+ and forces one of the rooks off of the 7th rank	_____	2B0314 1. ... Rxf2! and now 2. Qxf2 and Qc3 or Qb4 wins because of the pin on the Queen. if 2. Rxf2 Qd1 mate. If the white rook moves anywhere on the back rand, i.e. 2. Re1 Rf3+ wins easilty. White can delay things 1 move with 2. Qc7+ but after that
2B0322 Although good is 1. Bxb2, even better is 1. ... Be3! which wins at least a piece on move 2.	_____
