Of course g5 is better than g6! 1...g6 will result in 2 Qxg6# (f7 is pinned by Bb3)! With 1...g5 Black's king has the square h7 for a short escape! (If you need to see it on a diagram see post #160!)

g6 result's in, 2.Qxg6# result's in mate in two,not three like puzzle say's.f7 is pinned leaving g6 defensless,so Qg6#

Everyone talking about which is better between g5 and g6 and saying g5 is better, but it really isn't true. g6 is definitely the "better" move. Both moves are totally losing, but g6 forces the opponent so see one last tactic. It's the only practical try. You never know, your opponent might have a brainlapse :) g5 is as good as resignation.

Instead of 1...g6?! 2 Qxg6# you can resign as well!

Playing 1 Qg3 shows that White knows how to mate. By the way it's a problem and in a problem you should use Black's best defence - that's defenitely 1...g5 because it forces a mate in 3!

For a game probably it's the last chance ... (but don't put too much hope in it)!

Of course, against a player you respect you can resign after Qg3 :) But if it's blitz or you're against a weaker player then I think always try tricks until the bitter end. You'd be suprised how many games you can swindle that way!

"Playing 1 Qg3 shows that White knows how to mate. By the way it's a problem and in a problem you should use Black's best defence - that's defenitely 1...g5 because it forces a mate in 3!"

Best defense isn't always longest defense. Since a computer would evaluate both positions as simply "winning" for white, without a precise score, you should go for whichever is the most practical defense. g5 is just a pointless move, it achieves nothing. g6 has a small, incy wincy glimmer of hope :) Also, some people may just play Qg3 because it looks aggressive, without necessarily seeing the follow up. Just because you can see the mate doesn't mean your opponent can!

Best defence at a problem always means longest. Therefore mate in 3 can only be reached with best defence 1...g5! (As shown before 1...g6? is a mistake in a problem! 2 Qxg6# proves it!)

That's the difference between a game and a problem (called "Mate in n {moves}" - here n = 3)!

I can't believe you just gave g5 a ! :D

I would be willing to bet money that If you took a sample group of players of different strengths, and gave half the position after g6 and half the position after g5, some people (total beginners) will miss the g6 tactic, whereas anybody who sees the position after g5 will mate immediately. g6 is simply a better practical try. It isn't a mistake within a problem, it is a (very small) extra problem within a problem! And there are plenty of examples of puzzles in which one side plays an objectively worse move (for example, taking a decoy) in order to highlight the idea within a puzzle. There is no rule that all puzzles should be "best play"!
