Nb5+
If the other members do not misunderstand me puzzles of this kind create monologues. Puzzles must have some difficulty levels where it results in some discussion/dialogue because of which we learn from others and a bond develops among members.
On the earlier server the replies weren’t immediately visible, so many members posted answers. Some answers would be wrong even for simple problems, and other members would point out the errors. This ensured a dialogue.
On current server the replies are visible immediately. Once members see that someone else has posted the correct reply, they don’t post their own answers.
Even when someone sees that nobody has replied as uet, they avoid answering so that other members will get a chance.
End result is that overall responses and interaction has gone down.
I know this problem was fairly easy, but if one doesn’t have a lot of time, like myself, these type of problems provide a very enjoyable interlude, and I am grateful to the compilers.
I expected full solution by somebody by this time. undoubtedly 1.Nb5+ is the first move.
After 1…. Kc8
(1… Ka8 2.Rxa7#) what is the best move. Frankly the move I thought of immediately was 2.Rc7+ QxR winning Q for R. Though this also wins it is not the best. Proper is
2.Nxa7+ Kd8 3.Nxc6+ followed by 4.Qc7#. Properly all but I thought of it at first.
Black may delay it by one move by 1…. Rf4.
Heck! absent mindedly I typed “properly” for “Probably all but I”
My efforts to draw people into discussion has gone in vain.I abandoned 2.Rc7+ due to 2…. Kd8 3.RxQc6 Bxc6 when white gets Q for R but is there no mate by 4.Qc7+ Ke8 5.Nd6# ? Only the spoiler is 3….Rf1+ 4.Ka2 Bxc6 and black gets a flight square f8 for the king.However white gets B also but no immediate mate.
