I have also noticed this situation, it seems very often I will have a srtong hand and raise, just to have an agressive player push. Just today I was at a final table on a knockout tournament, there were 7 left and I was short stack at the table.
I hit pocket Queens, and I pushed, I got a caller with pocket 6 of course at the river I was 95% to win, when the river comes a 6. This seems to happen so often I sometines wonder if there isn't some funny business going on. But then occasionally I am the 5% that hits the river. It just seems to happen to some players much more often than others.
I often see guys pushing with virtually any 2 against strong hands and they seem to hit over and over again. You think well if they keep playing like that they will end up losing but they continue to hit lucky over and over again. I am sure that there is no logical explination for this, but do you have ANY insight on why some players seem to hit no matter what cards they play and no matter what they are up against?
