Sometimes I'll make a bet on the river to get some more money in the pot, on occasions this will be the minium. Isn't there a play in one of Harrington books (I assume it must be in the chapter on bluffing) where he describes the "post-oak bluff" where you put in the minium amount on the river to represent a big hand when in fact you have bugger all?
Yep, also looks better if when short stacked you dont go ai preflop even if your hand is shite.
Post oak bluff? Harrington the mug. I call it the "value-lookalike bluff" and i'v copyrighted that puppy.
