I'm really not sure that, on the EXTREMELY RARE occasions when I flop quads with a pair in the hole, I am playing the optimum strategy.
I have always believed that all you can do is check and call as you have the deck crippled and hope that an opponent or opponents catch something on the turn or the river.
But it never seems to happen. Usually it is checked all the way and I try a small bet on the river which never gets called. No one seems willing to have a go if flush or river cards come down.
I'm also wondering about when someone hits a full house against quads. I take the view that if that happens to me and my opponent is lucky enough to flop quads then I just have to pay him off. I don't know, maybe my opponents never hit boats against quads!
