Funny thing is I have recently been reading HOC (for the umpteenth time) because his basic strategy fits the live games in my area very well. His section on turn play sums up one pair saying if you have shown consistent strength in the hand and your opponent bets or raises - your top pair is "very unlikely" to be good.
You can't blame the attempt at logic by many in the general player pool. They understand through playing that when the bets get bigger on the turn the hand values need to be stronger. They think in a absolute sense. Leverage does not come into play often on the turn because of stack sizes. A decent percentage of these players will "spazz" from time to time. Learning to spot when that is about to happen is player dependent.
Here are two good examples from a 2/5 game I played in last night...
Regular raises pre to $15, two callers in position. Reg has $1,800. Relative unknown(who has LRR'd twice in last hour) has $575.
Flop($45): Q
5
3
Reg bets $25, guy calls.
Turn($95): 4
Reg bets $90, guy raises to $200 (with about $325 behind)...
What is his range? If you said 55, 33, A2 and 76 you are almost correct. You need to include A2o which is what he had. He showed after the reg 3-bet the turn all-in with AQ no .
Yours truly was UTG+1 with KK. UTG limps, Hero raises to $25, folds to UTG call.
Flop($50): J85r.
Check, Hero bets $40, call.
Turn($130): 7.
Check, check.
River($130): K no flush.
UTG bets $125, Hero raises all-in, UTG tosses in $100 more with 87s.
Why does this hand fit here? What does hero do if UTG bets the turn? Of course this would be a much more difficult question with deeper stacks.
