That was quick! Good points. I suppose the situation only arises occasionally in any case. And I have folded occasionally preflop to a reraise, but that is when I've raised with a truly shaky hand. I'd agree with the exploitation point, although hopefully one should try to fall into the exploiter not exploited side of the deal - and that calling raises on the flop/turn is a far more serious error, which should be avoided except when you have a very clear edge.

Thanks.
