Question about test 50 in "Winning Chess Tact - 2008/05/19 06:24
Hi, I'm working through Yassir Seirawan's "Winning Chess Tactics" and I'm finding the tests frustrating. Not that they are hard... just that some of the tests are not good problems because they are not clear cut. I'm getting 75-80% of them correct, and I find that the other 20% I'm pretty close or had the idea.
Anyway, test 50 is troubling. I attached an image of the position.
When I looked at this, knowing this was the "blowing away the King's cover" section, it was pretty clear that the answer (at least the first move) was Rxf6. I mean, this draws the g-pawn away from the king and the position is clearly better for white.
Now, can you predict how white wins? I sure can't. It depends so much how Black plays. If the test ends on just the first move, then I got it right... but what about subsequent moves? Isn't that the point of these tests? To see the entire lines?
Apparently after gxf6, Qg4 is the best move. I did not get this... so perhaps I should mark this test as "wrong" for me. But here's the funny thing. Yassir's analysis at this point completely defies what fritz and rybka say are the best moves for black at this point. The lines aren't even close. What Yassir says is a mate in 8, is completely thrown off because Fritz or Rybka can make this go on for much longer, even though white is clearly winning.
Which leads to another point. My answer, even though not Qd4, would have eventually lead to checkmate. I calculated the entire lines, choosing what I thought were the best moves... and White eventually won in 9 or 10 moves. Am I right, or am I wrong? I also considered some moves that Fritz ended up considered for black as well, which yassir completely ignored (which of course makes his calculation easier).
So how can you feel confident about the test answers where the moves the opponent can make are so varied? It's impossible to discover the true "answer" beyond the first move... unless they are forced or severely limited. In this case, black has tons of moves. Thoughts?
