I had this crazy player at my table.
He went all-in from middle position before the flop and before any had raised and he just doubled up with K4s against a JJ caller.
I was playing a last round before leaving the table as I had stacked up to 3.85 $ and accidentily stayed a round too long (posted blind already)
Now, he went all-in again without any caller and I was on the Big Blind with ATo and decided to call his 3.60 $ all-in. I won the hand with a pair of tens against his 87s (pair of 8's)
It made me think though. If you see a player going all-in preflop like a maniac and you're last to act, is it correct to call with hands like ATo or medium pockets ? It seemed more than probable that I had the better starting hand ...
