How bad do I suck at poker? Q7o in the BB flops a gutter...

[BigBaitsim (milo)]

Live 4/8 at Canterbury. Loose-passive game with 5-7 seeing the flop.

Milo is BB with Q7o. 5 limp, SB calls, Milo checks.

Flop is 458r. Milo bets...

I think this is about the worst bet ever. A friend and well-respected poster, thinks it was bad, but only marginally so.

Turn is a 6. Now I check, and it checks to the button, who bets. The plan was to CR, but now, still irritated with myself for betting a gutshot into a field of 6, I discover that I've just called. Lucky for me, these donkeys never fold... Except that this time they all fold except the button. Crap.

River is an A. Nice. I decide to CR the river, and instead I bet (clearly aliens have control of my brain and hand). Button raises, I three bet, he makes it 4 and I call.

Having played correctly preflop (not difficult, mind you), and horribly postflop, I gotta ask, which was worse, the flop bet or the turn call?
