Puzzle from Laszlo Polgar (Mate in two moves)

I hope you can solve in your mind before making a move. Also be host and comment how long it took you to solve.

First try. It took me about 4 seconds. Very unusual for me, but I saw it right away

About 5 seconds for me. Because Trysts claims to have done it in 4 seconds I  claim he cheated. :P

She, and I was being honest

It took me a while longer, I would say a minutes 10-12 minutes. It stumbled me a bit. @trysts

3.95 seconds

About 2 minutes

@CorrieG, no way these folks are doing it in 2-5 s

~30 sec.  I looked at Bc2 followed by Qb1 first.

No, really. I'm not lying. You're just going to have to accept that some puzzles you can see right away, while others not at all

2min. to sort out pieces,2min. for working protected squares.....and man i'm starved and it' movie time (the Snitch). Puzzle ? Promise to figure out Queen or rook sac. after--always 1 of them.

Because you say so right? :P

Mate in X puzzles are usually faster or easier to solve because you already have the target identified going into the puzzle (king) and how long it can take you (X moves). Usually mate in X puzzles have a forced sequence, so checks are usually the first move. This speeds up the solving process very quickly, especially this puzzle when there are a few pieces close together and for white only two pieces (exclude the pawn) can make the first move. It quickly becomes apparent which one that is, and there are only two forcing moves, or checks, so you simply do a quick calculation and bingo, got the puzzled solved.

well i stopped looking after 2 minutes. still for most its probably easy, but 2 seconds i hardly imagine that is true. 

~20 seconds

I like the other line better 1 ... Ka4 2. Bc2#

I Tried Rd3 before the Queen sac, I didn't realize it was pinned...

So I looked for another solution and realized that I could move it if I did Qc3 first.

It took me around one min.

ok then it just wasnt my day today

About 30 seconds.  Guess and check method (in my head, not on the board of course).

3 secs. It was the only way to get out of the pin quickly, but it took me longer to check it.
