i think the key is to give your potential monsters a chance to run onto second best hands.
a hand at martin's $50 6-max:
i had e35 (set got river by a 4-flush board and i didn't have time to reload). villain has e65 or so.
I got ATo and limp from MP, Villain calls from LP and BB checks (pot e1.75). board comes 3-flush to my ace. BB checks, I check, and Villain bets e1.50. BB folds. i do NOT have proper pot odds to peel one off, but i call. pot e4.75. turn is a blank, i check, Villain bets e2, and I call again without proper pot odds. pot e8.75 4th flush card hits on the river. i bet e5 as a value bet. he pushes and it amounts to about an e26 raise (the rest of my stack).
i call and take it down. he had a made J-high flush on the flop and screwed the pooch in a major way.
even if he had just called my river bet, i would have had decent implied odds (call e2 to win existing e6 pot plus e5 on the river). in retrospect, i probably should have bet e6 or e7 on the river to get better odds... but still. the fact that these guys get married to their hand and want to double up makes them vulnerable to plays like this.
another example...
I had AJ and checked or called (can't recall) in the BB. Flop gives me a gutter for the broadway str8 and middle pair. with pot about e2, i check and LP bets a euro. i call, and everyone else dumps. again, poor pot odds for me. blank on the turn, I check and Villain bets e1. i'm about 11-1 to hit the str8 (not counting hitting 2nd pr or trips as those may put me behind), but a call is 5-1 (or so). I call. River comes a K to complete the str8. I check, Villain wakes up and bets e10. I min-raise, fully expecting to split the pot or have Villain fold. He calls with QQ down and a flopped set. I win and take down an e45 pot.
in retrospect, chasing the gutter was probably not the best idea, as my trips would have made a boat possible and a second pair would have made the str8 possible for villain. anyway, the point is that these clowns will pay off big with a strong non-nut hand -- and they give you proper
implied odds to chase. my oesds and flush draws have rewarded me nicely.
