I was never a tournament player, preferring action. Point is it may be different playing competitively in tournaments, I don’t have a personal reference point for it, but I found that once I was at a certain level and in action all the time, there was no real practicing anymore. For me, nothing hones your game like competing. It may be different for tournament players, again I have no reference point for that
The thing about what you say though is that being an action and gambling is not sudden death. I played a zillion times and I end up starting off kind of slow don't seem to have it and then eventually grind the guy to pieces. In tournaments its not like that. You got to be 100% from the first time you come to the table. No time to get into the groove.
In tournament play that often is the problem even with champions. I've have beaten top players many times in tournaments cuz I just happened to get out of the box quicker on them in that match. Would I have ever gambled with them? Im not nuts. For the same reason, gambling it makes no difference how the session starts I can tell you how it would end against a better player.
I was at a tournament with Big Bob one time, and he was a terrible tournament player. He's playing this local guy and Bob loses raised to 11. The guys all excited, him and his friends high-five and going on and on. I guess it just got on Bob's nerves because he walked over to the guy and says "Would you like to play some for real now"?
Of course the guy can't say yes and it was probably a little rude of Bob to have done that but I guess it just got on his nerves and he was a little embarrassed.
