With ...Rb8 twice to follow.
[White "Computer - Hard"]
1. ---- Bxb2+ 2. Kxb2 Qa3+ 3. Kb1 Rfb8+ 4. Nxb8 Rxb8+ 5. Qb7 Rxb7+ 6. Ka1 Qb2#
For those like me who thought 3. ... c3+ would close the deal: white's king sneaks out the other way.
I believe c3+ looks correct...
I thought c3 works it just takes longer
The c3+ line has the white king moving to e3, which seems to be impossible. Is this a mistake in the analysis?
This solution is an error. c3+ must be correct.
Hey, need help . I made the right moves. But I still think that is mate with c3+ in 2 moves . With the Queen Qa3+ you need to sacrifice a rook and need 3 moves. But with c3+ you don't sacrifice rook and need only 2 moves. 1.c3+ Kc1 2 . Qa3+ Kb1 3. Qb2# . or 1.c3+ Kb1 2.Qxa2+ Kc1 3 Qb2# . And the last 1.c1+ Ka1 2 Qxa2# . If I wrong please correct me cause I can't see anything else.
c3+ seems the better of the two lines to me...
Do you mean this:
1.Nc6 Bxb2+ 2.Kxb2 c3+.
Then black has:
Not saying 25...c3+ is correct, but there is definitely an error in the analysis for it. The white King somehow manages to eat his own pawn
.. 25...c3+ is not correct because it is met by Kb3
The correct move here is 25...Qa3
I quite like this puzzle because it punishes hand waving. c3 looks good at first glance but you need to really calculate it to work out it isn't very good.
Good problem with an excellent distractor.
Very interesting with C3+. Having not included it as a candidate move in the first place, I didn't need to rule it out. I would have liked this one to be played out, though.
