You assume way too much I don't even know where to start:
1/ You assume the OP asked to raise the bet "out of frustration". Nowhere in his post did he say he was frustrated. He did say the kid was a poor mover, which means that the OP knew he got the upper hand in the game of chess. Remember that, from his own words, the OP has been "into pool halls from Michigan to Texas, from Tennessee to Wyoming and pretty much all the states in between" and has gambled with everyone. So one can reasonably deduct that the OP is an excellent player himself.
2/ You assume that the OP tried his best, and since the games were close, it's a close match. Fact is the OP dominated the kid to the tune of winning 86% of the games once the OP raised the bet. Even Jack Cooney would be proud of the OP.
3/ Unless you are the OP, or know the OP's speed well, it is totally baseless to assume that the OP was playing his best as you said.
Before we get off track, the topic is missing HEART. What I find ironic is that the OP got the cash -in a game where he clearly has the best of with all of his experience for being into every pool room in the country- yet the kid is called out???
I did assume a lot because when I read the OP's story it resonates with me. So unless the OP is a stone cold hustler in the vein of Jack Cooney and he is using this forum to ply his trade electronically I tend to empathize with him because as the story reads I have been there many times.
The reason the "kid" is getting called out is because the winner is being called a nit and a hustler because he wouldn't give up a lot of weight after winning a few games and making a tiny score.
Of course I don't KNOW all the facts so I am projecting my own experiences on top of the story.
Substitute my name with the OP and the story could have gone one of these two ways, as the story went with me eking out a small score OR with me going flat off after raising the bet with me thinking the whole time I should be winning. I can guarantee you that I would have lost far more than the kid did.
Had anyone walked into the pool after getting "called" to play me and asked me for ANY weight when they had no idea who I am then I would call them a heartless nit. That's just me. When I walk into a pool room and ask to play some then I am ready to play some with no weight just to see what I can do. I played the #1 player in China 2 years ago even 9 ball, 8 ball and one pocket. I walked right by the big ass poster with him holding a huge trophy and asked him to play some. I lost a couple hundred but I didn't whine and cry like scared puppy. Now if we play nine ball I get weight. If we play one pocket we play even even though I should get a couple balls because I like the challenge.
So to me there is NO WAY that the OP is a hustler. No way he hustled the kid. The kid tried to pull a move by asking for 10:7 AFTER his pool room buddies had already clocked the OP's speed. The OP didn't bite and asked to play cheap and the kid condescended to play for fifty a game even (probably thinking he was stealing). The OP lost several games thinking he should have won them and raised the bet to the kid's original $100. Now if the kid didn't think he was stealing at that point why would he agree to play $100 even when he originally wanted 10:7?
The point is that I THINK that the games were close, the bet was irrelevant, the kid could have quit even if he didn't like the game. In no way was he hustled and to tell the OP that he hustled the kid or was somehow being a nit for not giving up weight in a relatively even game was wrong and itself nitty.
Joe Salazar told me that in the old days you matched up with someone and if they pounded on you then you came back the next day and the day after than until you started beating them or you gave up and went looking for other opponents until you got strong enough to play them again. He said today's players wont stand still for a beating like the old timers. They won't get toughend up that way and consequently they are scared to jump up and play some against strangers.
When I grew up in the pool room me and several other guys would race other to the door to play any stranger who walked in. We were scared to death of being the one who didn't make a score. Sometimes the stranger would whip our asses and we would sit around all sad talking about it but the next stranger that walked in the door would get the same treatment. We didn't bet a lot because we didn't have a lot but we all had plenty of heart.
