A mate in 2 that took a GM 15 minutes to solve

Rook takes E4
King takes E4
Queen E2#

Took less than a minute

except that Kxe4 is a check.

Wow, that's an epic checkmate. I never would have seen Qf1 in a real game. Beautiful use of pins.

Qf1 -> Qf5#

There are really tough ones, sometimes 15 minutes is nothing.

Look at those ones:

@tanzids Are you a GM now, or how does that work?

OMG. Never cconsidered all those pins.

Love the pins in this one. Thanks for sharing @chaimzaromb

Some hints for solving composition puzzles. They will almost never start with a check or capture. Try to notice the theme that the puzzle is using as an aid to finding the key.
