6W0021 White won easily by playing 1. Qf4 which forces a queen trade which gives white an overwhelming endgame. Play might proceed 1. ... Qxf4 2. exf4 Rd4 3. e3! and now not Rxa4 because of 4. b6 attacking the rook and queening on move 6.	_____	6W0022 Just pushing the pawn will win, but slightly more to the point is 1. Kc3 (and faster) threatening 2. Kc2 which stops black fron queening and allows white to queen around move 6. If 1. ... Kb1? then 2. Kb4 wins the pawn.
6W0023 1. Nxd5! and the pin is fatal. Now if 1. ... Kd6 then 2. Nxc7 and the issue is if Black can draw by perpetual check. So now. 2. ... Qf4+ 3. g3! Qf2+ 4. Qg2 Qxg2+ 5. Kxg2 Kxc7 and 6. c3 gives White an easily won endgame.	_____	6W0024 1. Re7+ Kg8 (Worse is Kh8 after the following.....) 2. Qg5 and now the the threat of Qh6 is strong. if 2. .... Rxd3 3. Qh6 Qf6 4. Re8+! Rxe8 5. Rxe8+ Kf7 6. Qf8 mate. If 2. ... Nc8 3. Re6 Qf8 4.Qxg6+ and 5. Re8!! wins

6W0025 Interesting is 1. Qh3 (maybe also good is Rxb7) and now if 1. ... Ke7 2. Qh4+ Kf8 3. Qh8+ forking the king and rook. If then 3. ... Rg8 4. Qh6+ and now if 4. ... Rg7 5. Rg1 is crushing. If instead 4. ... Ke7?? 5. Qf6+ Kf8 6. Qxf7 mate.	_____	6W0026 1. Nxe6 fxe6 2. R1c7 and now the bishop of e7 is threatened. 2. ... Kf7 loses quickly to 3. Bg5 winning the bishop. If instead 2. ... Kf8 3. Bh6+ Kf7 4. Bg5 is the same. So if 2. ... Bd8 3. Rg7+ Kh8 4. Rxh7+ Kg8 5. Rcg7+ Kf8 6. Bh6!
6W0027 Tell me why the following wouldn't work: 1. Bxg6 and black gets mated if he doesn't take the bishop. So 1. ... fxg6 2. Rxg6+ and he gets mated if he doesn't take the rook. So 2. ... hxg6 3. Qxg6+ Kh8 and now 4. Re1 5. Re3 and 6. Rh3+ wins	_____	6W0028 1. Nxg6 (threat Ne7+ and then Qxh7 mate) fxg6 (if hxg6 then Rxg6+ mates easily) 2. Rxg6+ Kf7 (hxg6 then Qxg6+ mates next move) 3. Qxh7+ wins easily (Ke8 Re1+.) If 1. ... Kg7 2. Bh6+ kg8 (Kxf6 Qe5 mate) 3. Ne7+ Kh8 4. Bg7+ kxg7 5. Qh6+ wins with 6. Qxh7 mate

6W0031 [solution]	_____
6W0029 1. Rxh6 gxh6 2. Qxh6 f5 (the best defense) 3. Qg6+ Kh8 4. Bh6 with the threat of Qg7 mate. Now not 4. ... Rg8 5. Nf7 mate. So instead 4. ... Qe7 5. Bxf8 Qxf8 6. Nf7+ and black must give up his queen. I haven't verified this with a computer, but it looks correct to me. What do you think?	_____	6W0030 1. Ng5+ Kg8 2. Qe8+ Kg7 (if 2. ... Rf8 3. Qxg6+ forces mate.) 3. Ne6+ and now black might as well give up his Queen with Qxf6. But if 3. ... Kh7 4. Qxf7+ forces mate. if 3. ... Kh6 4. Qh8+ Rg7 5. Qf8+ forces mate on move 6. If 3. ... Kf6 4. Qh8+ forces mate on move 5. If 4. ... Rg7 then 5. Qxg7 mate. If 4. ... Ke7 5. Qd8 mate.
6W0031 Not 1. g6 stalemate. Also no good is to chase after the a4 pawn. Black has just enough time to win g5 and stop the a3 pawn. Also no good is 1. Kf6 Kh7 and now 2. g6 leads to stalemate and 2. Kf7 Kh8 gets nowhere fast. Instead the only thing that works is 1. Kg5 Kg8 2. Kh6 Kh8 3. g6 (White's last tempo move.) Kg8 4. g7 Kf7 5. Kh7 and then 6. g8=Q.	_____
