I know my least favorite part of winning is the moment of bluff! Especially when this bluff is on the final table and the stakes are very high. Sometimes I even get sweaty!
For me it comes in hands when I've outplayed my opponent. Just winning a hand is nice, but knowing you either got maximum value or pushed them off the better hand is what I like the most.
I usually play MTTs, so when I win a hand I'm more happy to increase my chips and have a bigger stack, to try to go further and survive for longer in the tournament! hhahahah
Stacking an opponents former chips onto my stack is a great feeling and I agree with others, getting maximum value and your opponent being completely stunned at the strength of my hand, adds to the rush big time.
You gain confidence, can avoid showing the cards and still be more comfortable. What you will do after that is what makes you great. Remember: With great powers come great responsibilities (Stan Lee)
