What would you do if you only had 5 seconds on the clock?
The first moves I look at, at any speed, are the checks.
Being human, under the pressure, I would play Qxf6+, as it also gains material (although it only leads to a draw). Qxc8+ also fits my criteria, but it moves the queen farther away, which just doesn't seem right.
The correct answer for the mate=in-two was aleady given but deleted by the post author.
