Yes a good play by the other player, departed is raising utg so hes possibly giving him some respect and has position post flop. Also if departed has a hand he has dominated hes giving himself a chance to take his whole stack. ...
hmmm, possibly but I would think it"s more likely excessive passivity.
a) it has been mentioned that the table was tight
b) AK is a drawing hand
c) the opponent didn"t raise (in this instance shove all in) on the very coordinated flop.
d) the opponent didn"t fold on the very coordinated flop
He"s a long way behind any made hand on that flop, and he"s a long way behind a pocket pair. If he doesn"t fill his flush or catch a King or an Ace he"s just donked off a vast proportion of his chips.
Compare that to reraising/shoving preflop - fairly safe likelihood of winning the pot there and then - at worst a race.
Raising/shoving postflop, you"re a long way behind AA, KK, any Q and a made flush.
But - what are the chances they"ve made the flush?
A pocket pair below a Q you will almost certainly get to fold.
A very tight player might even fold a low flush (they can"t have the nut flush after all) or a high pair.
And if they are beating you, and they do call, you still have a draw to the nuts.
Obviously folding post flop isn"t a bad idea either as it preserves his chips.
Because of these reasons I would surmise the opponent was just being too passive (rather than clever) and allowing himself to get outdrawn (although sadly that didn"t occur this time).
