There is a good line that I take vs. the wrong type of player often. Take this example. Villain is running 45/40 and has losing stats, and we are 100bb effective. We raise A8o from the button. Villain flats. The flop comes
864hh
We cbet, and villain raises. Against the most aggressive of opponents, a good line is often to flat the flop, fold to a turn bet on any 5, 7, or heart, and ship over his bet on any other card. However, against any opponent who is not hyper aggressive, this line is awful and the best play is to fold. I tend to give opponents at these stakes too much credit for being hyper aggro and too little credit for having a hand.
Another common spot I have trouble with is checkraising the flop for thin value vs. a player who is not very aggressive and getting 3bet, as shown below.
PokerStars No-Limit Hold'em, $0.50 BB (2 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com
SB ($39.80)
Hero (BB) ($58)
Preflop: Hero is BB with A, 10
SB bets $1.50, Hero calls $1
Flop: ($3) 4, 9, 10 (2 players)
Hero checks, SB bets $1.50, Hero raises to $5, SB raises to $13
I generally stack here, as I hate c/r fold for value, but I think against non-aggressive players it is correct to find a fold. I think there are quite a few other leaks I have playing ssnl/unl hu, and as I find them I will write about them here.
