Another Lethal Misclick

At the main event in Reno in March I bet something like 5500 when I meant to bet 1500, ran into a set, and made an early exit. Today's disaster went down like this:

I have around 29k chips (we started with 30k) a few hours in. I wasn't playing my best and left a 5k pot lying on the table once but I had made a couple excellent plays as well. 200-400 blinds, 50 ante. Everyone folded to me in the small blind and I completed with As3d. The BB checked. I bet 500 on the QsTs7s flop and he quickly called. I really didn't think he had a flush since he called so fast. The turn was the 6c, I checked, he bet 1000 pretty fast, and I made it 3000 to go. He quickly flung in a grey/red 1000 chip and a purple/pink 5000 chip from a "dirty stack" of chips and said something like "oh shit" or "oh no." It was pretty clear he had screwed up and meant to call unless it was an extremely well-acted angle shoot. The Bellagio is using these new tournament chips that are a bit confusing in terms of color-coordination and mistakes like this were happening all day. I thought for about a minute and a half and then went all-in for about 21,000 more. He called after about 15 seconds with 9s8c, the river was the Qh, and I was gone. It probably would have gone check-check or check-fold on that river.

That's likely the last hand of poker I'll play in a casino in 2006, and possibly the last hand of any kind of poker. I go home on Monday.
