In Free-rolls especially, you do get a few "Bingo Player's" that just don't give a damn because it is free and they are losing nothing, but you can get them in Live games as well.
Playing in a Cash Game at a local Pub, they had Blinds of 25 Pence and 50 Pence every hand just to try and keep the game Friendly and not get too far out of hand.
When a stranger who had never been before, started to raise pre-flop by 10X and 20X the BB, he basically was running the table and stealing every blind, until I was dealt a monster pair and I shoved all-in against one of his £10 Pound raises, he folded immediately and I showed Pocket Kings, a couple of
hands later he started doing his old trick of raising to big for the size of the blinds and I shoved over him again, this time I showed a 7/2 suited when he folded, and I said don't try conning money out of us, because next time I will have a hand.
He immediately left and never came back.
At the end of the day I didn't give a damn about how much I could lose, because I only bought in for £30 and it was money I was willing to lose, but I didn't like him being so aggressive in a Friendly game we played every week.
Money becomes Immaterial when you buy-in for what you are willing to lose, and I consider the buy-in "Dead Money" it is not mine anymore, it only belongs to the Prize pool or the Cash on the table, It is my job to win it back, if I play correctly and can win it back.
Sometimes I win, Sometimes I lose, but the important part is, that it is money I am willing to Pay, to Play a game I Love and Enjoy.
When the fun Stops, STOP!
